peer connect-interface (BGP/BGP-VPN instance view)
Syntax peer { group-name | ip-address } connect-interface interface-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-type interface-number: Specifies the type and number of the interface.
Description Use the
peer connect-interface command to specify the source interface for
establishing TCP connections to a peer/peer group.
Use the
undo peer connect-interface command 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] 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).
