Example
The following example shows the assignment of descriptive text to a VRF.
console(config)#ip vrf Red
console(config-vrf-Red)#description “Backbone to Gateway”
console(config-vrf-Red)#exit
ip vrf
This command creates a virtual router with a specified name and enters
Virtual Router Configuration mode. If the virtual router instance already
exists, it simply enter virtual router configuration mode. This command
optionally reserves the number of routes allowed as well as sets the maximum
limit on the number of routes for a virtual router instance, in the total routing
table space for the router, provided there is enough free space in the router’s
total routing table.
Syntax
