Parameter
Parameter | Description |
vrf <vrf-name> | Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>]. |
| neighbor <protocol bgppeer>neighbor <ip> | Specifies an IP address of neighborthe IP address of a peer. |
| peer-group <peer-group> | Specifies a peer group. |
| interface <interface> | Specifies an interface for BGP connection. |
Usage Guidelines
Allow BGP to negotiate the extended-nexthop capability with it’s peer. If you are peering over a IPv6 link-local address then this capability is turned on automatically. If you are peering over a IPv6 Global Address then turning on this command will allow BGP to install IPv4 routes with IPv6 nexthops if you do not have IPv4 configured on interfaces.
Example
• This example enables advertisement of IPv4 prefixes with IPv6 next hops over global IPv6 peerings.
