Specifying the Source Interface of a Route Update Packet
Generally, the system specifies the source interface of a route update packet.
When the interface fails to work, in order to keep the TCP connection alive, the
interior BGP session can be configured to specify the source interface. This
command is usually used when using the loopback interface.
Table 105 Specifying the Source Interface of a Route Update Packet
Operation
Specify the source interface of a route update
packet
Use the best source interface
By default, BGP carries out TCP connection with the optimal source interface.
Configuring the BGP MD5 Authentication Password
BGP uses TCP as its transport layer. For security, you can configure a MD5
authentication password when setting up TCP connection. BGP MD5
authentication only sets a password for the TCP connection, but not for
authenticating BGP packets. The authentication is implemented by TCP.
Perform the following configurations in BGP view.
