Operation Command
Configure to send the community
attributes to a peer group

VII. Configuring the repeating time of local AS BGP records the passed AS numbers in the routing informatio n, and checks route loop
depending on whether the AS number are repeated. In some special applications, it is
allowed to receive the routing information with the repeated AS number.
Perform the following configuration in BGP view.
Table 21-15 Configure the repeating time of local AS
Operation Command
Configure the repeating time of local AS peer { group-name | peer-address }
allow-as-loop [ number ]
Remove the repeating time of local AS undo peer { group-name |
peer-address } allow-as-loop
By default, the allowed repeating time of local AS is set to 1.
VIII. Specifying the source interface of a route update packet Generally, the system specified the source interface of a route update packet. When
the interface fails to work, in order to keep the TCP connection valid, the interior BGP
session can be configured to specify the source interface. This command is usually
used on the Loopback interface.
Table 21-16 Specify the source interface of a route update packet
Operation Command
Specify the source interface of
a route update packet peer { peer-address | group-name }
connect-interface interface-type interface-name
Use the best source interface undo peer { peer-address | group-name }
connect-interface interface-type interface-name
By default, BGP uses the interface to establish BGP links for the source interface of a
route update packet.
