enable bgp neighbor address-family l2vpn-evpn

enable bgp {neighbor [remoteaddr | all]} {{address-family} l2vpn-evpn} next-hop-unchanged

Description

Enables overriding the BGP specification behavior with respect to the next-hop of routes advertised to EBGP peers.

Syntax Description

bgp Specifies BGP.
neighbor Specifies BGP neighbor.
remoteaddr Specifies BGP neighbor IP address.
all Specifies all BGP neighbors.
address-family Specifies address family.
l2vpn-evpn Specifies L2VPN EVPN address-family type.
next-hop-unchanged Enables preserving the BGP next-hop when routes are advertised to EBGP peers (default is disabled).

Default

Default is that next-hop-unchanged is disabled.

Usage Guidelines

This command enables overriding the specification behavior with respect to the next-hop of routes advertised to EBGP peers. Specifically, it maintains the BGP next-hop for routes advertised to EBGP peers instead of replacing the next-hop with either the outgoing interface IP address or the local loopback address.

When enabling the address family l2vpn-evpn in an EBGP configuration, the option next-hop-unchanged must also be enabled.

Example

The following example enables next-hop unchanged for BGP neighbor at 192.168.66.2:

# enable bgp neighbor 192.168.66.2 l2vpn-evpn next-hop-unchanged

History

This command was first available in ExtremeXOS 30.2.
