Ok, that much I sort of guessed, but is there as simple answer to my followup question: - if router2 is not reachable, obviously packets matching prefix2/L can be sent to router1. But, is there any advice on algorithm how the system detects if router2 becomes available? Just wait for RA? Probe with some logic?. (There is no RA in IPv4 -- I think this should work for IPv4 too!) Ok, so my address matches the route for router2, but this router is currently unreachable (no entry in neighbor cache). Do I a) drop the packet b) if there is a reachable router with shorter matching prefix, send there I guess (b), but then the question is when and how is router2 "rediscovered". I'm pretty sure I can invent some ad hoc algorithm, but I also wanted to know other opinions? -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
