Functional Notes
This command allows an eBGP neighbor to be on a network that is not directly connected. Normally, eBGP
peers are directly connected. In certain applications, a non-BGP device such as a firewall or router may
reside between eBGP peers. In this case, the eBGP multihop command is required to allow updates to
have a TTL greater than 1 and to allow received BGP updates to be added to the BGP table when the next
hop address is not directly connected.
Usage Examples
The following example allows a BGP message to travel 10 hops to a neighbor:
(config)#router bgp-neighbor 192.22.73.101
(config-bgp-neighbor)#ebgp-multihop 10
61200990L1-35E
Specifies the maximum hop count of BGP messages to a neighbor.
Range: 1 to 254.
