In last Decemeber I tried to get some clarifications to the IS-ROUTER bit handling in NA. Apparently my interpretation still differs from TAHI, and as I have hard time deciphering the rules from RFC-2461, I would like present the question here.
In TAHI section "R flag vs. IsRouter" flag, there are following tests unicast rso NA w/o TLL exp:updated unicast rso NA w/ TLL, diff. LLA exp:unchanged Why in first case the ISROUTE is supposed to be updated? Because TLL is not present, it seems to me that logically we don't know whether LLA is same or not, so we should not change ISROUTER. Similarly, unicast rsO NA w/o TLL exp:updated unicast rsO NA w/ TLL, diff. LLA exp:updated the latter is clear, we have the address and update it, but the first NA does not have TLL, so why should ISROUTE be updated? -------------------------------------------------------------------- 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] --------------------------------------------------------------------
