Configuring Acceptance of IPv6 Packets with Zero Hop-Limit

The ipv6-reject-zero-hop-limit and no-ipv6-reject-zero-hop-limit statements are used to enable and disable rejection of incoming IPv6 packets that have a zero hop-limit value in their header.

By default, such packets are rejected both when they are addressed to the local host and when they are transiting the router. To accept zero hop-limit packets addressed to the local host, include the no-ipv6-reject-zero-hop-limit statement at the [edit system internet-options] hierarchy level. Transit packets are still dropped.
