NHRP in a Classic IP Environment with non-NHRP Device
This example shows how NHRP can be used between two 1577 devices. when one
of them does not support NHRP. Here, Device2 provides the NHRP client with the
ATM address of the non-NHRP device and the client can establish a shortcut for
traffic to the non-NHRP host. However, when traffic flows from the non-NHRP
device, it flows on the routed path to Device2; then Device2 acts as an NHRP client
and establishes a shortcut to the destination.
