Static Routing
The system supports static network route configuration on a per context basis. Define network routes by specifying the:
IP address and mask for the route
Name of the interface in the current context that the route must use
Next hop IP address
Important:
On the ASR 5000, static routes with IPv6 prefix lengths less than /12 and between the range of /64
and /128 are not supported.
Adding Static Routes to a Context
To add static routes to a context configuration, you must know the names of the interfaces that are configured in the
current context. Use the show ip interface command to list the interfaces in the current context (Exec mode).
current context. Use the show ip interface command to list the interfaces in the current context (Exec mode).
Information for all interfaces configured in the current context is displayed as shown in the following example.
[local]host_name# show ip interface
Intf Name: Egress 1
Description:
IP State: Up (Bound to slot/port untagged ifIndex 402718721)
IP Address: 192.168.231.5
Subnet Mask: 255.255.255.0
Bcast Address: 192.168.231.255
MTU: 1500
Resoln Type: ARP ARP timeout: 3600 secs
L3 monitor LC-port switchover: Disabled
Number of Secondary Addresses: 0
Total interface count: 1
Intf Name: Egress 1

IP State: Up (Bound to slot/port untagged ifIndex 402718721)
IP Address: 192.168.231.5
Subnet Mask: 255.255.255.0
Bcast Address: 192.168.231.255

L3 monitor LC-port switchover: Disabled
Number of Secondary Addresses: 0
Total interface count: 1
The first line of information for each interface lists the interface name for the current context as shown in the example
output. In this example, there is one interface with the name Egress 1.

Notes:
You can configure a maximum of 1,200 static routes per context. Save your configuration as described in the
Verifying and Saving Your Configuration chapter.
