peer connect-interface (BGP/BGP-VPN instance view)

Syntax peer { group-name ip-address } connect-interfaceinterface-type interface-number

undo peer { group-name ip-address} connect-interface

View BGP view/BGP-VPN instance view

Parameters group-name: Name of a peer group, a string 1 to 47 characters.

ip-address: IP address of a peer.

interface-typeinterface-number: Specifies the type and number of the interface.

Description Use the peer connect-interfacecommand to specify the source interface for establishing TCP connections to a peer/peer group.

Use the undo peer connect-interfacecommand to restore the default.

By default, BGP uses the outbound interface of the best route to the BGP peer/peer group as the source interface for establishing a TCP connection to the peer/peer group.

Note that:

To establish multiple BGP connections to another BGP router, you need to specify on the local router the respective source interfaces for establishing TCP connections to the peers on the peering BGP router because the local BGP router may fail to establish TCP connections to the peers when using the outbound interfaces of the best routes as the source interfaces.

Examples # In BGP view, specify loopback 0 as the source interface for routing updates to the peer group test.

<Sysname> system-view [Sysname] bgp 100

[Sysname-bgp] peer test connect-interface loopback 0

#In BGP-VPN instance view, specify loopback 0 as the source interface for routing updates to the peer group test (the VPN has been created).

<Sysname> system-view [Sysname] bgp 100
