IP Locking is an EOS feature configured on an Ethernet Layer 2 port. When enabled, it ensures that a port will only permit IP and ARP packets with IP source addresses that have been authorized. As of EOS-4.25.0F release update, IP Locking can run in two modes - IPv4 Locking (which will be referred to as IP Locking) and IPv6 Locking, which can be configured using the commands mentioned in the below sections. IP Locking prevents another host on a different interface from claiming ownership of an IP address through either IP or ARP spoofing.

The document describes an extension of the decap group feature, that allows IPv6 addresses to be configured and used as part of a group. IP-in-IP packets with v6 destination matching a configured decap group IP will be decapsulated and forwarded based on the inner header. That will allow any IP-to-IP packet type to be decapsulated, i.e. IPv4 in IPv4, IPv4 in IPv6, IPv6 in IPv4 and IPv6 in IPv6.
