Applicable Platforms
This command applies to the NetVanta 300, 1000R, 2000, 3000, 4000, and 5000 and Total Access 900
Series units.
Command History
Release 8.1 Command was introduced.
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
