Using Site Manager
Configuring a Stub Area
A stub area does not import ASEs and may or may not import internal route
summaries. In place of routes to destinations outside the stub, a border router
connected to a stub injects a default route advertisement. When an internal router
encounters a datagram addressed to a destination outside the stub, the router
forwards it to the border router specified in the default route advertisement.
Assume, for example, that the stub area in Figure 7-1
on page 7-5 has been
configured to import no internal or external routing information. border router 8
receives ASEs and internal summaries from its interface to the backbone.
However, border router 8 does not forward the ASEs or summaries to the stub.
Instead, it injects a default route that internal routers use to forward datagrams to
destinations beyond the stub.
