neighbor statement can take either an IP address to setup a single
neighbor, as the example shows for
203.0.113.14, or it can take a name which
configures a peer group. The command changes to BGP neighbor mode, indicated by
config-bgp-neighbor prefix in the prompt.
Peer groups work nearly identical to neighbors, and they define options that are
common to multiple neighbors. To configure a neighbor as a member of a peer
peer-group <group name> to the
Within BGP neighbor mode, the most important directive is
remote-as to set
the AS number of the neighbor. In this case, the AS number of the neighbor is
65005. The majority of other neighbor configuration is handled by the
neighbor definition for a specific address family.
The default state of a neighbor is disabled down.
To enable the neighbor, enter the
enable command in BGP neighbor mode.
