SROS Command Line Interface Reference Guide BGP Neighbor Configuration Command Set

ebgp-multihop <hop count>

Use the ebgp-multihopcommand to configure the maximum hop count of BGP messages to a neighbor. Use the no form of this command to return to the default setting.

Syntax Description

<hop count>	Specifies the maximum hop count of BGP messages to a neighbor. Range: 1 to
	254.

Default Values

By default, ebgp-multihop is set to 1.

Command Modes

(config-bgp-neighbor)# BGP Neighbor Configuration Mode

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>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 exampleallows a BGP message to travel 10 hops to a neighbor:

(config-bgp-neighbor)#ebgp-multihop 10
