ebgp-multihop

E Commands

This chapter describes the Cisco NX-OS Border Gateway Protocol (BGP) commands that begin with E.

ebgp-multihop

To configure the exterior Border Gateway Protocol (eBGP) time-to-live (TTL) value to support eBGP multihop, use the ebgp-multihop command. To return to the default setting, use the no form of this command.

ebgp-multihop ttl-value

no ebgp-multihop ttl-value

Syntax Description

ttl-value

TTL value for eBGP multihop. The range is from 2 to 255. You must manually reset the BGP sessions after using this command.

Command Default

None

Command Modes

BGP neighbor configuration mode

Command History

Release	Modification
5.2(1)N1(1)	This command was introduced.

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
