A QoS Policy-maps policer is said to be shared when “set-policer” action is present under the qos features ( qos ip, qos ipv6, qos mac ) of a TCAM profile. When such shared QoS policy-map with policer action is configured on multiple interfaces, the policer instance is shared among all the interfaces, the policy-map is applied on. If in case, a unique policer instance is required per interface, a duplicate policy-map needs to be created for each interface, which will require additional TCAM resources.

Unicast Reverse Path Forwarding (uRPF) can help limit malicious IPv4/IPv6 traffic on a network. uRPF works by enabling the router to verify reachability (routing) of the source IP address (SIP) in the packet being forwarded. If the SIP is determined to be an invalid address, the packet is dropped.

Virtual Private LAN Service (VPLS) appears in (almost) all respects as an Ethernet type service to customers of a Service Provider (SP). A VPLS glues together several individual LANs across a packet switched network to appear and function as a single bridged LAN.
