Configure Redistribution to BGP+ for VRF 0 (GRT)
Configure an IPv6 redistribute entry to announce IPv6 routes of a certain source protocol type into the BGP domain, for example, static, OSPF, IS-IS, RIPng, or direct routes. Use a route policy to control the redistribution of routes.
Note
When a route map with attributes set to origin and local-pref is applied to the BGP redistribute command, the attributes are not applied to the redistributed routes.
Before you begin
-
If required, a route policy exists.
Procedure
Example
Specify a route policy to govern redistribution by using the following command:
Switch:1>enable Switch:1#config terminal Enter configuration commands, one per line. End with CNTL/Z. Switch:1(config)#router bgp Switch:1(router-bgp)#redistribute ipv6–direct route-map policy2
