This document details a complete implementation of the SBC's RBA Feature.

Prerequisites

The RBA feature requires the latest ASM image. Be sure that the HQ ASM is upgraded to the latest image version.

Install the Lync Server Resource Kit on the Lync Server. You will want the Bandwidth Policy Server Monitor Application to verify the dynamic CAC Profile changes. See the Microsoft Lync Server site to obtain the Resource Kit and installation instructions.

Additional Notes
  • The RBA Feature is only supported between two Ribbon SBC nodes.
  • The RBA Feature requires an ASM installed on the HQ SBC.

SBC Configuration

This quick start document shows the steps and interlational parameters required to configure a UX to successfully route calls. The configuration process of a UX should always begin with running a wizard; however, the wizard only needs to be run for the very first configuration.

There are many different architectures which might be used for connecting remote sites to a main site. The manual pages for this 3G4G feature specify a VLAN switch with the 3G4G and WAN networks sharing a single port of the UX.

The implementation below uses a 3G4G router connected to the remote LAN segment, thus dedicating the WAN connection to a SBC port. This configuration elminates then need for a VLAN-capable switch.

Prerequisites

As a prerequisite to installing the RBA feature, check the following items:

  • STUN Setting on the SBC
  • Installed ASM Image
  • RBA License
  • DNS Configuration

STUN Setting

Configure Send STUN Packets to Enabled in the Media | Media System Configuration. Refer to Configuring the Media System.

RBA Image

Ensure the SBC software and ASM image are updated to the latest. Refer to Upgrading or Downgrading the SBC 1000/2000.

These instructions detail the use of an SBA image rather than the RBA image. Both images perform equivalent functions for the RBA implementations. In fact, a future SBC version will use a single image for both SBA and RBA. For now, you may use either the RBA or SBA image when installing the 3G4G Backnet feature.

Ensure the ASM is running an SBA image compatible with the Lync Server.  For example, running Lync 2013 requires the Lync 2013 SBA image. To reinitialize the ASM, refer to Re-initializing the ASM.

Check the RBA License

Verify that your SBC is licensed for the RBA feature.

Check RBA License

 

 

DNS Configuration

Add both SBCs to the DNS server. In the example, SBC2000 is the HQ SBC and SBC1000 is the remote network SBC. The DNS server is configured only with the LAN-side IP addresses of these nodes, 10.1.1.74 and 10.1.2.71, respectively.

Add the FQDNs and IP addresses for nodes that are part of the RBA feature:

  • Remote-network SBC
  • HQ SBC
  • HQ ASM
  • Lync Server

IP Routing

Ensuring the WAN and IPsec traffic use the appropriate routes is crucial to successful RBA failover.

SBC 1000 Static Routes

  1. Click the Settings Tab and select Static Routes.

  2. On the remote-network SBC, add a Static IP Route

  3. Create a default route that points to the WAN interface on the HQ SBC. Set the Metric to 1.

  4. Create another default route that points to the IPsec interface on the HQ SBC. Set the Metric to 2.

    Default routes are required for the automated routing failover to function. Only use default routes.

  5. Verify the newly added static routes via Static IP Route Table.

SBC 2000 Static Routes

On the HQ SBC, add specific subnet routes that point to the remote-network. One route should use the remote-network SBC's WAN connection (metric 1), the other should point to the Internet gateway (metric 2).

  • When the WAN is up, the WAN-specific route to the remote-network will be used.
  • When the WAN is down, the default Internet router will be used to send the traffic via the 3G4G carrier network.

 

SIP Server Tables and Signaling Groups

Configure the SIP Servers and Signaling Groups for both HQ and remote-network SBCs.

SBC 1000 SIP Server Table

  1. Select SIP Server Tables.

  1. On the HQ SBC, add a Signaling Group that points to the remote-network SBC

  2. On both SBCs, ensure that the Signaling Groups is Up.

Verification

Verifying Routing

On the HQ SBC, verify that the Routing Table shows the route to the remote network using the WAN IP address of the remote SBC. For example, the route to 10.1.2.0 (remote network) uses the remote SBC's 134.56.242.16 as the gateway.

Using a Command Prompt window from a PC on the remote network.

  • Ping the FQDN of the remote SBC. It should return remote-side private IP address (10.1.2.71 in this example).

    C:\Users\Administrator.SBC>ping sbc1000.sbc.net

Pinging sbc1000.sbc.net [10.1.2.71] with 32 bytes of data:
Reply from 10.1.2.71: bytes=32 time<1ms TTL=64
Reply from 10.1.2.71: bytes=32 time<1ms TTL=64

Ping statistics for 10.1.2.71:
    Packets: Sent = 2, Received = 2, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

  • Then ping the FQDN of the HQ SBC. It should return the IP address on the private side of the HQ network (10.1.1.74 in the example, not134.56.242.15)

    C:\Users\Administrator.SBC>ping sbc2000.sbc.net

Pinging sbc2000.sbc.net [10.1.1.74] with 32 bytes of data:

  • Ping the FQDN of the Lync Server
  • Ping the FQDN of the Domain Controller
  • Ping the FQDN of the DNS Server
  • Ping the FDQN of the RBA

All the returned IP addresses must be on the private-side of the HQ network (e.g. 10.1.1.x)

From a PC on the HQ side of the network

  • Ping the FQDN of the Remote SBC. It should return a remote LAN IP address.

    C:\Users\Administrator>ping sbc1000.sbc.net

Pinging sbc1000.sbc.net [10.1.2.71] with 32 bytes of data:
Reply from 10.1.2.71: bytes=32 time=5ms TTL=63

Ping statistics for 10.1.2.71:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 5ms, Average = 3ms
  • Ping a PC on the remote LAN. Check that the default router on the remote LAN PC is set to the (remote) SBC's LAN interface address (10.1.2.71 in the example).

Test a Lync to Lync Call

At this point you should be able to call Lync-to-Lync over the WAN.

Creating the IPsec Tunnel

Use the following steps to configure an IPsec tunnel between the remote and HQ SBCs.

SBC1000 IPsec Configuration

The following steps configure the remote SBC to generate an IPsec tunnel to the HQ SBC when the WAN is down.

  1. Click IPsec > Tunnel Table in the left-hand navigation.

  2. Add a Tunnel Table

  3. Enter the configuraton information for your IPsec tunnel.
    • The Local Subnet Address must be programmed with IP information for the remote network.

    • The Remote Subnet Addressmust be programmed with IP information for the HQ network.

SBC2000 IPsec Tunnel Configuration

The following step configure the HQ SBC to receive an IPsec tunnel from the remote SBC when the WAN is down.

  1. Configure an IPsec tunnel on the HQ SBC with information appropriate to your network. On the HQ SBC, the Local Subnet Address is the HQ network, the Remote Subnet Addressis the remote network subnet(s).

Verification

In this section you will test the IPsec tunnel to ensure connectivity exists when the WAN link is down.

Preparing for Verification

  1. Pull the cable from the WAN port on the Remote SBC. You must pull the cable from the WAN port on the Remote SBC for this verification step. Downing the WAN port results in automatically disabling the WAN IP route.

  2. Manually remove the WAN Route from the HQ SBC

  3. On the Remote SBC, use the refresh button to verify the Service Status is Link Up.

  4. The Signaling Groups should come back up after the IPsec tunnel is esablished.

Verifying PC Connectivity

  1. From a remote LAN PC, ping the FQDN of the HQ SBC. Note that the Round Trip Time (time) is much longer than that for the ping over the WAN link.

    root@sbc1000:~# ping sbc2000.sbc.net
PING sbc2000.sbc.net (10.1.1.74) 56(84) bytes of data.
64 bytes from 10.1.1.74: icmp_req=1 ttl=64 time=76.2 ms

^C
--- sbc2000.sbc.net ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1000ms
  1. Make a Lync call from between remote and HQ lync clients. The clients should ring and answer.

Re-add the HQ SBC WAN Route

Before proceeding, replace the HQ SBC WAN route to the remote SBC.

 

Configuring for Automated Switchover

With the successful testing of the static IPsec tunnel, it is time to make the tunnel dynamic so that the 3G4G link is only used activated when the WAN is down.

  1. Modify the Remote SBC IPsec Tunnel Activation to Link Monitor Action and click OK.

SBC 1000 CAC Profiles

The CAC profiles are transmitted to the Lync Server via the HQ SBC when the WAN transitions link states.

Create the CAC Profiles on the Remote SBC

  1. Click WAN in the left-hand navigation and select CAC Profiles.

  2. Create a profile for the WAN up situation. Set the bandwidths according to your desired WAN link configuration and capacity. Click Apply.

  3. Now, create a CAC profile for WAN down. Setting the Bandwidth State to Disabledresults in any HQ<>remote-network calls being routed over the PSTN.

SBC 1000 Link Monitor Configuration

The Link Monitors provide the ability for the remote SBC to know whether the WAN is up and available.'

  1. Click Link Monitor Configuration.

  2. Add a monitor to monitor the public IP interface of the HQ SBC and click Apply.

  3. Add a monitor to monitor the 3G4G router port. Associate this Link Monitor with the IPsec Tunnel you recently created. With this link activated (due to WAN down), the IPsec tunnel will be automatically started.

Verification

Verify the following tables on the remote SBC.

SBC 2000 Link Monitor Configuration

Configure a Link Monitor on the HQ SBC in order that it may dynamically adjust its internal routing table when the WAN link switches. The Link Monitor is configured to monitor the WAN side only.

  1. Create a fake CAC entry. This entry will be ignored for purposes of bandwidth adjustment.

  2. Create a Link Monitor that monitors the WAN interface of the remote SBC.

Verification

Verify the condition of the routes and IPsec links.

WAN Link Up

HQ SBC

With the WAN link up, the HQ SBC routing table and Link Monitor should appear.

Remote SBC

  1. With the WAN link up, the remote SBC's routing table should point to the WAN interface on the HQ SBC.

  2. The Link Monitor Table should be Ready on the WAN link.

  3. The IPsec tunnel should be Link Down.

Lync Server

Verify the Lync Bandwidth Profile using the Bandwidth Policy Service Monitor, which is installed as a component of the optional Lync Server Resource Kit (available from the Microsoft Lync Server website).

  1. Open Windows Explorer to C:\Program Files\Microsoft Lync Server 2013\ResKit\BandwidthPolicyServiceMonitor and select PDPMonUI.exe.

    Select PDPMonUI.exe

     

     

  2. Expand the server name in the left-hand navigation and select the expanded server.

    Expanded Server Name

     

     

  3. Click the Topology Infotab

    Topology Info tab

     

     

  4. Verify the bandwidth settings are for the WAN up values.

    Verify Bandwidth Settings

     

     

Lync Clients

Test a call between a HQ and Remote Lync client. Calls between HQ and Lync clients should connect directly over the WAN without need for a PSTN connection.

 

WAN Link Down

Downing the WAN Link should result in the following status. With the WAN link down, verify your implementation to the following:

HQ SBC Status

  1. On the HQ SBC, the WAN Link Monitor should show down and the IPsec tunnel up.

Remote SBC Status

On the Remote SBC, the Link Monitor should show the 3G4G link up, the WAN link down, and the IPsec tunnel up.

 

Lync Server

Within two or three minutes, the Bandwidth Policy should automatically update to the WAN down bandwidth values.

Bandwidth Policy Update

 

Lync Clients

Test a call between a HQ and Remote Lync client. In the WAN down condition, you should be able to call between HQ and Remote Lync clients. The calls should utilize the PSTN connection between the SBCs.

Remember, for Lync implementations, the SBC is a PSTN gateway for the Lync Server. When in the WAN down condition, the Lync server will send calls to the remote PSTN (SBC) gateway. You must configure the customary SBC routes and transformation tables that would be used for calls to/from Lync.

 

Setting the Remote SBC to TLS

The remote SBC must beconfigured to TLS/SRTP in order for the remote Lync clients to send calls over the PSTN during a 3G4G failover. The following steps will assist you in configuring the Lync Server and remote SBC for TLS/SRTP.

  1. On the Lync Server, start the Topology Builder and Edit Properties for the remote site Trunk.

    Edit Properties

     

     

  2. Change the port and configuration to support TLS as shown.

  1. As an IP router, the SBC forwards the SIP request from the remote Lync to the Lync Server
  2. Lync server sends a SIP request to the remote SBC (as a SIP --> PSTN gateway)
  3. Remote SBC dials the HQ SBC via PSTN
  4. HQ SBC (as a SIP Gateway) sends a SIP request to the Lync server
  5. Lync Server sends SIP Request to the HQ Lync client
  6. Remote Lync client audio bypasses directly to the remote SBC.

Troubleshooting

This section contains troubleshooting tips and suggests for various issues that may arise during RBA implementation.

Prepare SBA not run

A wireshark trace which shows an exception due to an unrecognized cmdlet is likely due to the Prep SBA function not being executed. Review the Configuring the RBA section of this document.

Prep SBA Function Not Executed

 

RBA computer not a member of RTCUniversalServerAdmins group

Should the CAC bandwidths fail to change when the active link is switched between the WAN and the 3G4G link and this message appears in the RBA system Event Log, then the RBA computer (ASM) is not a member of the RTCUniversalServerAdmins group. See the Domain Controller Configuration section of this document.
