Cisco Systems 3560 Manual De Usuario

These are the Layer 3 features:

Some features noted in this section are available only on the IP services 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 (requires the IP services image)

Enhanced Interior Gateway Routing Protocol (EIGRP) IPv6 to utilize IPv6 transport, 
communicate with IPv6 peers, and advertise IPv6 routes

HSRP for IPv6 (requires the IP services image)

Border Gateway Protocol (BGP) Version 4 (requires the IP services image)

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

Multiple VPN routing/forwarding (multi-VRF) instances in customer edge devices to allow service 
providers to support multiple virtual private networks (VPNs) and overlap IP addresses between 
VPNs (requires the IP services image)

Fallback bridging for forwarding non-IP traffic between two or more VLANs (requires the IP 
services image)

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 (requires the IP services image)

Multicast Source Discovery Protocol (MSDP) for connecting multiple PIM-SM domains (requires 
the IP services image)

Distance Vector Multicast Routing Protocol (DVMRP) tunneling for interconnecting two 
multicast-enabled networks across nonmulticast networks (requires the IP services image)

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 (requires 
the IP services image)

IPv6 default router preference (DRP) for improving the ability of a host to select an appropriate 
router
