Advertising Networks in an AS
Follow these steps to advertise networks in an AS:
1. Use the network command in Router Configuration mode to advertise BGP peers
in other ASs about the networks in which your AS originates:
MOT(config-bgp)#
network <
1-65535
> [ mask <
A.B.C.D
>]
where:
1-65535
is the network that BGP advertises.
mask is the keyword for specifying network or subnetwork mask.
A.B.C.D
is the network mask.
