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

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

  1. Enter BGP Router Configuration mode:

    enable

    configure terminal

    router bgp

  2. Create a redistribution instance:

    redistribute <ipv6-direct|ipv6-isis|ipv6-static|ospfv3|ripng>

  3. Optional: If required, specify a route policy to govern redistribution:

    redistribute <ipv6-direct|ipv6-isis|ipv6-static|ospfv3|ripng> route-map WORD <0–64>

  4. Optional: If required, configure a route metric:

    redistribute <ipv6-direct|ipv6-isis|ipv6-static|ospfv3|ripng> metric <0–65535>

  5. Enable the instance:

    redistribute <ipv6-direct|ipv6-isis|ipv6-static|ospfv3|ripng> enable

    Unlike IPv4 redistribution, you do not need to manually apply the IPv6 redistribution instance. After you enable the IPv6 redistribution instance, it is automatically applied.

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

Variable Definitions

The following table defines parameters for the redistribute <ipv6-direct|ipv6-isis|ipv6-static|ospfv3|ripng> command.

Variable

Value

enable

Enables the BGP route redistribution instance. The default value is none.

metric <0–65535>

Configures the metric to apply to redistributed routes. The default value is 0.

route-map <WORD 0-64>

Configures the route policy to apply to redistributed routes. The default value is none.
