A network that resides within an Autonomous System (AS) is said to originate from that network. To inform other ASs about its networks, the AS advertises them. Border Gateway Protocol (BGP) provides three ways for an AS to advertise the networks that it originates:

■ Redistributing static routes

■ Redistributing dynamic routes

■ Using the network command

It is important to remember that routes advertised by the techniques described in this section are advertised in addition to other BGP routes that a BGP-configured router learns from its internal and external neighbors. BGP always passes on information that it learns from one peer to other peers. The difference is that routes generated by the network and redistribute router configuration commands specify the AS of the router as the originating AS for the network.
