Configure redistribution to BGP+ for VRF 0
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.

If required, a route policy exists.
Procedure
