Re: Latest NHRP draft

[[e-mail]]

Bruce,

Can you elaborate on how rate limiting would prevent
multiple VCs from occuring when the NHRP request goes through multiple
NHSs towards its destination. Does this method guarantee that multiple
VCs will not occur? Can you provide more explicit justification for this?
If the source has multiple NHRP requests within a short period of time,
would rate limiting affect the subsequent requests?

Thanks,

Derya

I was answering that yes this could happen, but rate limiting of NHRP
traffic could still cause router D to only receive 1 request.
