Enables overriding the BGP specification behavior with respect to the next-hop of routes advertised to EBGP peers.
| 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 is that next-hop-unchanged is disabled.
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.
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
This command was first available in ExtremeXOS 30.2.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature, see the Switch Engine v33.1.1 Licensing Guide document.
