Is there a possibility to apply predefined QOS on the tunnel interfaces between the hub and the spokes. Ali Hawar February 12, at a. Up to this point the tunnels have been configured as cleartext for the sake of simplicity, but in the real world we probably want to include IPsec encryption to protect tunnels traversing an untrusted path. Efren October 31, at p. Jana December 7, at a. Thus, the end to end semantics of this extension are preserved without causing changes to existing implementations. Any help would be much appreciated.

The Next Hop Resolution Protocol (NHRP) is an extension of the ATM ARP routing mechanism that is sometimes used to improve the efficiency of routing computer network traffic over Non-Broadcast, Multiple Access (NBMA) Networks.

    It is defined in IETF RFCand further described in RFC The NHRP forms a part of the Multiprotocol Encapsulation over ATM (MPOA).

    The first thing you're likely to notice is that the tunnel does not have an explicit destination specified. Could this have been an IOS issue? In case of manual keying, this duration can be infinite.

    It is interesting to note that, in our scenario, designation as the NHS is the only attribute which distinguishes R1 as the hub router.

    Hi, I would just like to start of by saying this article is great, it keeps things really simple and is a thousand times betetr than the way Cisco tries to explain it. This extension is defined in contrast to the NHRP Authentication Extension defined in [1] which has hop by hop semantics. Split horizon was preventing the routes from being distributed.

    This way dynamically the addition or removal of spokes could be learnt by other active spokes. As always the best understandable explanation on Cisco topics. All backup works fine. I configure track as well.

    The length of the authentication data field is dependent on the hash algorithm used. This is great!
