Filtering of a Peer

interior BGP session can be configured to specify the source interface. This
command is usually used on the Loopback interface.
Table 363 Specify 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 uses the interface to establish BGP links for the source interface of
a route update packet.
Configuring BGP MD5 authentication password
BGP uses TCP as its transport layer. For the sake of high security, you can configure
MD5 authentication password when setting up a TCP connection. In other words,
BGP MD5 authentication just sets password for TCP connection, but not for
authenticating BGP packets. The authentication is implemented by TCP.
Perform the following configuration in BGP view.
Table 364 Configure BGP MD5 authentication
Operation
Configure MD5 authentication
password
Cancel MD5 authentication
In BGP, no MD5 authentication is performed in setting up TCP connections by
default.
The multicast extension configured in BGP view is also available in MBGP, since
they use the same TCP link.
Switch 8800 Family series support filtering imported and advertised routes for
peers (groups) through Route-policy, AS path list, ACL and ip prefix list.
The route filtering policy of advertised routes configured for each member of a
peer group must be same with that of the peer group but their route filtering
policies of ingress routes may be different.
Perform the following configuration in BGP view.
