Hi, Discussing one implementation, a possible source of ambiguity in RFC2461 came up.
RFC2461 discusses that next-hops must be on-link. However, section 8 on redirect basically requires: - routers know each others' link-local addresses (not an issue from hosts' perspective, just use routing protocols or other mechanisms) - hosts are able to verify that the redirect comes from the link-local address the host is currently using as its next-hop The latter is a bit problematic. How could the host know this in the case where the next-hop has been configured using e.g. a _global_ (but on-link) address? What's the deal here? -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
