Enabling BGP
To enable BGP, a local AS number must be specified. After BGP is enabled, the
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 peer command. When BGP is disabled, all established BGP
connections will be disconnected.
Perform the following configurations in system view.
