Hi Donald and Benson,
Thank you very much for your responses.
The link you shared is the only useful document I was able to find. I followed the instructions and omitted the “tunnel protection” part as I don’t need encryption. Unfortunately, the GRE tunnels do not work and debug logs error messages regarding missing VICI profile.
Having read the last paragraph of the document about tight integration with IKE, as well as the post below, I assumed that it might not be possible to configure NHRP without IPSec, hence I posted the question here to make sure.
The post I referred to earlier:
One thing to note is that I am trying to set up NHRP between FRR and A cisco ASR router.
Thank you very much again!
John
Hi, John.
The documentation that Donald shared will probably be helpful. Note that NHRP needs some kind of underlying encapsulation (i.e. a tunnel) in order to be applicable. But it doesn't necessarily have to use IPsec. For example, GRE is a common choice (with or without IPsec).
Cheers,
-Benson
