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
Default Level
2: System level
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; otherwise, 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).
