Chapter 1 Overview
Features
Layer 3 Features
Layer 3 features are only available when the switch is running the metro IP access image.
• 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
• 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
Layer 3 VPN Services
These features are available only when the switch is running the metro IP access image.
• Multiple VPN routing/forwarding (multi-VRF) instances in customer edge devices (multi-VRF CE)
to allow service providers to support multiple virtual private networks (VPNs) and overlap IP
addresses between VPNs
• Multicast virtual routing and forwarding (VRF) Lite for configuring multiple private routing
domains for network virtualization and virtual private multicast networks
• VRF and EIGRP compatibility
Monitoring Features
• Switch LEDs that provide port- and switch-level status
• MAC address notification traps and RADIUS accounting for tracking users on a network by storing
the MAC addresses that the switch has learned or removed
