Unicast reverse-path forwarding (uRPF) is a security feature that validates the source IP address of an incoming packet to ensure that the incoming packet has originated from a legitimate/valid source.  If validation of the source IP address fails, then the packet is dropped, thus preventing IP spoofing from illegitimate/invalid sources.

This document is an extension to the Decap Group feature, that allows IPv6 addresses to be configured and used as part of a decap group. Now we will be able to configure IPv6 prefixes as a decap group. Tunneled packets with IPv6 destination matching to a configured prefix decap group will be decapsulated and forwarded based on the inner header. IP-in-IP tunnel type will be supported for prefix based decap groups.

This document describes the CLI introduced to change the default hardware FEC allocation scheme for IPv4/IPv6 attached routes. By default, level2 hardware FECs are allocated for attached IPv4/IPv6 routes. To change the default hardware FEC allocation scheme, this CLI can be used.
