Description: This MIB module defines management objects for the Multicast Switching features on Cisco Layer 2/3 devices.

Definition of some of the terms used in this MIB:

Multicast Replication - The mechanism by which a system creates one or more copies of a multicast packet for forwarding.

Ingress Multicast Replication - A type of multicast replication where the replication engine on the ingress module always performs the whole replication.

Egress Multicast Replication - A type of multicast replication where the replication engines on both the ingress and egress modules perform the replication.

VPN - Virtual private network. A secure IP-based network that shares resources with one or more physical networks.

VRF - VPN Routing and Forwarding instance Consists of an IP routing table, a derived forwarding table, a set of interfaces that use the forwarding table, and a set of rules and routing protocols that determine what goes into the forwarding table.

MVPN - Multicast VPN

MVRF - Multicast VRF A VRF which has multicast routing enabled.

VRF-lite - A feature that enables a service provider to support two or more VPNs, where IP addresses can be overlapped among the VPNs.

LTL - Local Target Logic A hardware resource table to aid in switching.

OIF - Outgoing Interface The interface through which packets are forwarded out.

DF - Designated Forwarder.
