8.3.4 (Optional) Configuring the Local Interfaces Used for BGP4+
Connections
When establishing BGP4+ peer relationship between two devices through various links, you
need to specify the local interface during the setup of a BGP4+ session on the devices.
Context
Do as follows on the BGP4+ router:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
peer { ipv6-address | group-name } connect-interface interface-type interface-
number [ ipv6-source-address ]
The source interface and source address used to set up a TCP connection are specified.
Usually, BGP4+ uses the physical interface that is directly connected with the peer as the session
interface used for the TCP connection.
To increase the reliability and stability of the BGP4+ connections, configure the local interface
used for the BGP4+ connection as the loopback interface. In this way, when there are redundant
Issue 01 (2012-03-15)
The peer or peer group is configured only to listen to connection requests, but not to
send any connection request.
After this command is used, the existing peer relationship is removed. The peer on
which this command is used reestablishes the peer relationship after receiving the
connection request from its peer. After this configuration is done, the conflict of
connection requests is avoided.
NOTE
This command can be used on only one of two peers. If this command is used on the two peers,
the connection between the two peers cannot be established.
6. Run:
ipv6-family [ unicast ]
The BGP IPv6 unicast address family view is displayed.
7. Run:
peer { ipv6-address | group-name } enable
An IPv6 peer is enabled.
After configuring a BGP4+ peer in the BGP view, enable the peer in the BGP IPv6
unicast address family view.
