Hi,
I am curious on what the implementations on the relay routers do, when encapsulating packets
using 6to4 anycast address (192.88.99.1) ? At least there is the issue of fragmentation at the
IPv4 level where when multiple relay router is sending packets to the same 6to4 router, the 6to4
router may not be able to properly reassemble as the same fragment id could be used by both
relay routers. I saw some discussion in draft-savola-v6ops-6to4-security-01.txt which recommends
that relay routers should use 192.88.99.1. Not sure what implementations do. Does the 6to4
router implementations verify to make sure that the source address used is 192.88.99.1 in this case ?
