With the branch extender in place the backbone network’s view of the branch extender is as a giant end node with all the downstream LUs being owned by this giant end node.

So, for “one-hop” routing this operation happens once during transfer of a packet from its source to its destination. v The IBM implementation can operate in networks where some routers do not support NHRP .

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 .

NHRP in a Pure LAN Emulation Environment In the LAN emulation case, routers use the IBM extensions to provide NBMA information for devices on their ELANs.
