I got few queries about the IPv6 protocol.= 1. Is it possible that a NS and RS message size can very depending up=on the imlimentaion (If any one is appending the other extension header bef=ore attaching the ICMPv6 header and RS message content to the IPv6 header) =? 2. or is it fixed, means we are bound that we should not attach any =extension header for these messages? 3. If RS or NS message size excee=ds the MTU the node fragments the packet and sends it to any other node (I= am assuming other node as router). Router should except this packet and sh=ould process it after assmbling the packet or it should discard it? 4.= If any router finds that after building the response for message total len=gth is greater than MTU should it fragment it and send or should not send?= 5. if we specifically talk about ICMPv6 Echo Request, say if a node i=s sending ICMPv6 Echo Request after fragmenting it(because payload is too l=ong), should the target node(router) send all the payload back in reply aft=er fragmenting the packet or should it put as much as mtu is not met and= discard the rest payload?
