Purpose
Specifies the autonomous system number and enters the BGP
configuration mode, allowing you to configure the BGP
routing process.
Specifies the IPv4 address family unicast and enters address
family configuration mode.
Exits router address family configuration mode, and returns
to BGP configuration mode.
Enters neighbor group configuration mode.
Configures TCP maximum segment size. The range is from
68 to 10000.
Specifies the IPv4 address family unicast and enters address
family configuration mode.
Exits router address family configuration mode.
Exits the neighbor group configuration mode.
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.
