NHRP to an Egress Router
The source and/or destination stations of protocol traffic do not have to belong to
subnets served by NHRP participants. They may access the ATM network via
routers that communicate with the NHRP devices. In this case, the 2210 provides
shortcuts through the ATM network to eliminate as many hops as possible.
