In this section:

Scenario

Establish configuration to support a new carrier peer "Carrier-C" given the existence of the carrier peers configured in the preceding deployment scenario. This carrier's IP addresses overlap with another carrier's IP addresses.

Background Information

Ports and IP Interface Groups have been configured as described in NNI: Complex route selection.

Workflow

  1. Create a new Address Context "AC2".

  2. Set "CLI context" to Address Context AC2

  3. Create IP Interface Group "LIFGroup2" with qualified name "AC2.LIFGroup2".

  4. Create and configure IP Interface AC2.LIFGroup1.LIF1 in IP Interface Group AC2.LIFGroup1.
    Set LIF1 name/IP address/netmask/VLAN tag

  5. Associate IP Interface "LIF2" with Port "Port2"

  6. Create a Zone with name "Carrier-C". Explicitly associate this Zone with LIFGroup2. This assignment restricts all traffic within this Zone to pass through LIFGroup2.

  7. Create a SipSignalingPort "SignalingPort2" for this Zone. Set "SipSignalingPort2" IP  address. UDP, port 5060 is set as default; no TLS by default.
    1. Qualified name is "AC2.Carrier-C.SipSignalingPort2".
    2. Carrier-C will direct traffic to this SipSignalingPort IP address.

  8. Create a SipTrunkGroup with name "MNServiceGroup1" within Zone "Carrier-C".

    No specific Profile references are set, so all are set to the Default Profiles.



  9. Create one (e.g.) Ingress Peer Prefix; 1: 2.2.2.0/24; within "MNServiceGroup1" representing the range of IP addresses expected as source addresses from Carrier-C.

  10. Set up routing to route calls starting with "978" and "617" to Carrier-A Create RoutingLabel "ToCarrier-A" and set RoutingLabelRoute within it Specify IP Peer Group as the SipTrunkGroup "GCServiceGroup1" Specify SIP Peer (SIP Server) "GCPeer" IP address: 1.1.1.2

  11. Create Routes to route calls starting with "978" and "617":
    1. Route 1:
      Set "Destination National" field to "978"
      Set Routing Label field to "ToCarrier-A"
    2. Route 2:
      Set "Destination National" field to "617
      Set Routing Label field to "ToCarrier-A"
  12. Set up routing to route calls starting with "303" to Carrier-C Create RoutingLabel "ToCarrier-C" and set RoutingLabelRoute within "ToCarrier-C" RoutingLabel:
    1. Specify IP Peer Group as the SipTrunkGroup "Carrier-CServiceGroup1"
    2. Specify SIP Peer (SIP Server) "Carrier-CPeer" IP address as 3.3.3.2
    3. Create Route to route calls starting with "303":
      Set "Destination National" field to "303
      Set Routing Label field to "ToCarrier-C"
  13. The system should now be able to take traffic from Carrier-A and Carrier-B and route calls to area codes 978, 617, and 303 accordingly.
