`neighbor ebgp-multihop`

Syntax

neighbor {<IP-ADDRESS>|<PEER-GROUP-NAME>} ebgp-multihop <HOP-COUNT>

no neighbor {<IP-ADDRESS>|<PEER-GROUP-NAME>} ebgp-multihop <HOP-COUNT>

Description

This command enables BGP to establish connection with external peers residing on networks that are not directly connected.

By default, external BGP peers must be directly connected. If external BGP peers are not connected directly, then this command is enabled to initiate the connection with that external peer. If the command is disabled and external BGP peers are indirectly connected, then BGP peer session will not be established.

The neighbor connection must be reset using clear bgp <NEIGHBOR-IP-ADDRESS> to allow this configuration to take effect.

The no form of this command disables the peer ebgp-multihop feature.

Command context

<IP-ADDRESS>: Specifies an IP address.

Enabling BGP to establish connection with external peers residing on networks that are not directly connected:

switch(config-bgp)# neighbor 1.1.1.1 ebgp-multihop 5
switch(config-bgp)# no neighbor 1.1.1.1 ebgp-multihop

Disabling BGP to establish connection with external peers residing on networks that are not directly connected:

switch(config-bgp)# neighbor pg ebgp-multihop 5
switch(config-bgp)# no neighbor pg ebgp-multihop
