set protocols bgp neighbor capability extended-nexthop

The set protocols bgp neighbor capability extended-nexthop command enables advertisement of IPv4 prefixes with IPv6 next hops over global IPv6 peerings, adding the extended-nexthop capability to the global IPv6 neighbor statements on each end of the BGP sessions.
The delete protocols bgp neighbor capability extended-nexthop command disables advertisement of IPv4 prefixes with IPv6 next hops over global IPv6 peerings.

Command Syntax

set protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> | interface <interface>} capability extended-nexthop

delete protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> | interface <interface>} capability extended-nexthop

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 <ip>	Specifies the IPv4/IPv6 address of a peer.
peer-group <peer-group>	Specifies a peer group.
interface <interface>	Specifies an L3 interface for BGP connection. The value could be a VLAN interface name, loopback interface name, routed interface or sub-interface name.

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.
