The metro base image provides basic Metro Ethernet features.
The metro access image includes additional features such as IEEE 802.1Q tunneling, Layer 2
protocol tunneling, dynamic ARP inspection, and IP source guard.
The metro IP access image adds Layer 3 functionality such as IP routing support for Routing
Information Protocol (RIP), Open Shortest Path First (OSPF) Protocol, Border Gateway Protocol
(BGP), and Enhanced Interior Gateway Routing Protocol (EIGRP), multiple VPN
routing/forwarding on customer edge devices, (multi-VRF-CE), and IP multicast routing
Protocol-Independent Multicast (PIM) sparse mode (SM) and dense mode (DM).
Unless otherwise noted, all features described in this chapter and in this guide are supported on
