What should be the behavior of a router when it receives an IPv6 packet with Hop Limit = 0 ? Does IPv6 have the same behavior as for IPv4 TTL ?
Following are some extracts of RFCs. ---------------------------------- (Extract from RFC 1812 -- requirements for ipv4 routers) 4.2.2.9 Time to Live: RFC 791 Section 3.2 Note in particular that a router MUST NOT check the TTL of a packet except when forwarding it. A router MUST NOT originate or forward a datagram with a Time-to-Live (TTL) value of zero. A router MUST NOT discard a datagram just because it was received with TTL equal to zero or one; if it is to the router and otherwise valid, the router MUST attempt to receive it. -------------------------------------------- (Extract from RFC 2463 -- ICMPv6) 3.3 Time Exceeded Message If a router receives a packet with a Hop Limit of zero, or a router decrements a packet's Hop Limit to zero, it MUST discard the packet and send an ICMPv6 Time Exceeded message with Code 0 to the source of the packet. This indicates either a routing loop or too small an initial Hop Limit value. -------------------------- Kind regards, Christophe.
