Static IP Routes for IP Interfaces

The staticRoute object is used to configure static IP routes for the IP interfaces. A static route indicates the nextHop gateway and IP interface that is used for a particular peer network IP prefix.

A route preference may be configured for static routes as shown in the command syntax. The lower the preference value, the more likely the route is to be used.

Notes

  1. Static routes using a specific ceName can only be added for packet interfaces.
  2. The SBC does not allow to delete the ceName separately.
  3. A static route is deleted only from the instance in which it is configured, and not from both active and standby instances of a SBC HA pair configuration.
  4. The configuration of a staticRoute with respect to a ceName cannot be edited. If any change is desired in the configuration, delete the staticRoute and reconfigure it.

 

Note

The SBC 52x0 and SBC 7000 systems support creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.

(This ability does not apply to the SBC 51x0 and SBC 5400 systems which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restriction.)

For complete details, refer to Configuring IP Interface Groups and Interfaces.

Command Syntax

% set addressContext <addressContext_name> staticRoute <destinationIpAddress> <ip_prefix_length> <nextHopIPaddress> <ipInterfaceGroupName> <ipInterfaceName> 
	condition ceName (node name)
	preference <100-2147483647>
 
% show addressContext <addressContext_name> staticRoute
 
% delete addressContext <addressContext> staticRoute <IpAddress>

Command Parameters

Static Route Parameters

Parameter

Length/Range

Description

addressContext

1-23

<addressContext_name> – The name of the address context. The address context is a container of objects that correspond to a specific IP Addressing domain.

staticRoute

N/A

<destinationIpAddress> – The destination IP address. The following IP address types are supported:

  • IPv4 – This is V4 IP address in dotted decimal form (for example 128.127.50.224).
  • IPv6 – This is V6 IP address in hexadecimal/colon   form (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880).

<ip_prefix_length>

0-128

The IP prefix length of this static route entry.

<nextHopIPaddress>

N/A

The IPv4 or IPv6 address of the next system en route to the destination.

<ipInterfaceGroupName>

N/A

The name of the IP interface group.

<ipInterfaceName>

N/A

The name of the IP interface for this entry.

conditionN/A

For an SBC HA pair configuration (only), use this object to define the routes added to this SBC HA pair.

  • ceName – The name of the computing element that hosts the port used by the IP interface (length: 1-255 characters).

NOTE: The SBC supports only the ceName condition in this release.

NOTE: Before configuring the condition with a specific ceName, the ipInterfaceGroupName and ipInterfaceName parameters must first be configured for this Static Route. These three parameters cannot be configured using the same commit. For further details, refer to IP Interface Group - CLI.

NOTE: The condition option is only applicable to non-management interfaces.

preference

100-2147483647

<preferenceNumber> (default = 100) – The route preference value. The management route preference range is 1-99 and the packet route preference range is greater than or equal to 100.

 

Command Example

To display static routes:

% show addressContext default staticRoute
staticRoute 10.6.30.105 32 10.34.26.1 LIF2 lif_eth3 {
    preference 10;
}
staticRoute 10.34.9.70 32 10.34.25.1 LIF1 lif_eth2 {
    preference 10;
}
staticRoute 10.34.9.95 32 10.34.26.1 LIF2 lif_eth3 {
    preference 10;
}
staticRoute 10.34.13.194 32 10.34.25.1 LIF1 lif_eth2 {
    preference 1;
}
staticRoute 10.34.13.195 32 10.34.26.1 LIF2 lif_eth3 {
    preference 10;

Static Route for Management Interfaces

The staticRoute object is used to configure static IP routes for the management interfaces. A static route indicates the nextHop gateway and management interface that is used for a particular peer network IP prefix.
