NHRP

With the CLIP, (as mentioned before), inter-LIS communications have to go through routers. This is not an optimal solution when both nodes communicate with each other are attached to the same ATM network. A mechanism is needed for an end system to resolve the IP address of another end system in a foreign LIS into the corresponding ATM address. The NBMA (Non Broadcast, Multi Access) NHRP protocol, developed by the IETF, overcomes this limitation and provides this mechanism.

Possible bugs/limitations encountered in Cisco’s RIP implementation

  1. Default route origination not working reliably.
  2. Automatic summarization turned on causes major networks to be propagated throughout the RIP domain with a metric of 1.
  3. Using RIPv2 on NBMA hub-and-spoke topology causes the hub router to rewrite the next hop field in the RIPv2 update to the IP address of the spoke router advertising the originalupdate, thereby creating reachability issues
