Usage Guidelines

Use the ebgp-multihop command to configure the eBGP time-to-live (TTL) value to support eBGP multihop. In some situations, an eBGP peer is not directly connected to another eBGP peer and requires multiple hops to reach the remote eBGP peer. You can configure the eBGP TTL value for a neighbor session to allow these multihop sessions.

This command requires the LAN Enterprise Services license.

Examples

This example shows how to configure the eBGP multihop value:

switch(config)# router bgp 1.1
switch(config-router)# neighbor 192.0.2.1 remote-as 1.2
switch(config-route-neighbor)# ebgp-multihop 2
