By default, BGP route dampening is not configured.

It must be noted that the parameters in the command are interdependent. If one 
parameter is configured, other parameters must be specified.

BGP can transmit the internal network information of local AS to other AS. To 
achieve the purpose, the network information about the internal system 
discovered by the local router via IGP routing protocol can be transmitted.

Perform the following configurations in BGP view.

By default, BGP does not import the route information of other protocol.

The specified and imported source route protocols can be direct, static, rip, isis, 
ospf, ospf-ase, and ospf-nssa.

For detailed description of routing information, refer to “Importing Routing 
Information Discovered by Other Routing Protocols” in Chapter 43 “IP Routing 
Policy Configuration”.

This command can be used to configure the repeating times of local AS number.

Perform the following configurations in BGP view, VPNv4 view and VPN instance 
view.
