Which packet types are implicitly permitted by IPv6 ACLs?

  • router solicitation packets
  • IPv6 unicast packets
  • neighbor discovery packets
  • ping packets

Explanation: IPv6 access lists include two implicit permit entries by default. These two permit entries allow neighbor solicitation and neighbor advertisement packets (both of which are part of the neighbor discovery protocol) to pass through the interface for IPv6 to MAC address resolution.
