RE: RFC 2461 : Neighbor Discovery



Hi JINMEI and Hesham,

I am looking for “Router to Router” connected by PPP links (POS) running
IPV6CP.  

Since ND is a union of (ARP, ICMP Rotuer Discovery, ICMP Redirect and
others), which part of ND is needed (or has to be implemented) in both
Routers. 

Thanks in advance,
Subu

I think the original question is rather vague:

about which part of ND the question is asking (RFC2461 or RFC2462,
which part of each spec, etc).

Additionally, from the latter part of this thread, there seems to be
another confusion on whether we are only concentrating on routers,
only on hosts, or on both.

For further constructive discussion, these points should be clarified
in the first place, IMO.
