You can use Site Manager to perform these operations on an OSPF virtual link.
Defining a Range for a Summary Route
Border routers generate summary advertisements for their attached areas. Each
summary advertisement specifies a range of destinations in an area. An area range
specification consists of a network address and a variable-length mask. For
example, a summary advertisement for the destination 140.191.0.0 with a mask of
255.255.0.0 describes a single route to the collection of destinations 140.191.0.0
to 140.191.255.255. When a packet is forwarded, it is always forwarded to the
network that is the best (longest or most specific) match for the packet’s
destination.
An address range is associated with an interface to an area. You can use Site
Manager to define a range for an area.
Configuring Border Services for a Stub
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.
