Reset BGP connection

To enable BGP, local AS number should be specified. After the enabling of BGP, 
local router listens to BGP connection requests sent by adjacent routers. To make 
the local router send BGP connection requests to adjacent routers, refer to the 
configuration of the 

 command. When BGP is disabled, all established BGP 

connections will be disconnected.

Perform the following in the System View.

By default, BGP is not enabled.

Perform the following configurations in BGP view.

By default, no network route is advertised by the local BGP network.

The BGP speakers who exchange BGP packets form a peer. A BGP peer cannot 
separate from its peer group and exists independently. In other words, a peer must 
belong to a specific peer group. To configure a BGP peer, you must first configure 
the peer group and then add the peer into the peer group.

In the case of any change in the configuration of the group, configuration of each 
group member changes accordingly. Users may, however, configure certain 
attributes for certain member by designating its IP address so that the member is 
not affected by the group’s configuration in terms of these attributes.

 Perform the following in the BGP view.

Before configuring a BGP peer, you must configure the peer group that the peer 
belongs to first.
