Layer 2 Virtual Private Network Services; Layer 3 Features - Cisco ME 3400 Software Configuration Manual

Chapter 1 Overview

Layer 2 Virtual Private Network Services

Layer 2 virtual private network (VPN) features are only available when the switch is running the metro
IP access or metro access image.

Layer 3 Features

Layer 3 features are only available when the switch is running the metro IP access image.

IEEE 802.1Q tunneling enables service providers to offer multiple point Layer 2 VPN services to
customers
Layer 2 protocol tunneling to enable customers to control protocols such as BPDU, CDP, VTP,
PAgP, LACP, and UDLD protocols to be tunneled across service-provider networks.
HSRP Version 1 (HSRPv1) and HSRP Version 2 (HSRPv2) for Layer 3 router redundancy
IP routing protocols for load balancing and for constructing scalable, routed backbones:
RIP Versions 1 and 2
–
– OSPF
– EIGRP
– BGP Version 4
IS-IS dynamic routing
–
BFD protocol Bidirectional Forwarding Detection (BFD) Protocol to detect forwarding-path
–
failures for OSPF, IS-IS, BGP, EIGRP, or HSRP routing protocols
IP routing between VLANs (inter-VLAN routing) for full Layer 3 routing between two or more
VLANs, allowing each VLAN to maintain its own autonomous data-link domain
Policy-based routing (PBR) for configuring defined policies for traffic flows
Static IP routing for manually building a routing table of network path information
Equal-cost routing for load balancing and redundancy
Internet Control Message Protocol (ICMP) and ICMP Router Discovery Protocol (IRDP) for using
router advertisement and router solicitation messages to discover the addresses of routers on directly
attached subnets
Protocol-Independent Multicast (PIM) for multicast routing within the network, allowing for
devices in the network to receive the multicast feed requested and for switches not participating in
the multicast to be pruned. Includes support for PIM sparse mode (PIM-SM), PIM dense mode
(PIM-DM), and PIM sparse-dense mode
Support for the SSM PIM protocol to optimize multicast applications, such as video
Multicast Source Discovery Protocol (MSDP) for connecting multiple PIM-SM domains
DHCP relay for forwarding UDP broadcasts, including IP address requests, from DHCP clients
DHCP for IPv6 relay, client, server address assignment and prefix delegation
IPv6 unicast routing capability for forwarding IPv6 traffic through configured interfaces using static
routing, RIP, or OSPF
