Here is an example of what RIP configuration would look like:
Switch# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)# ip routing Switch(config)# router rip Switch(config-router)# network 172.16.0.0 Switch(config-router)# end
As you will notice, there is nothing unique about this routing protocol configuration, the same goes for all of the other supported protocols. The one thing you will see is that we entered the 搃p routing?command in global configuration mode. This command is required if you are going to transform the switch from a layer 2 device to a device capable of routing IP packets.
HSRP
HSRP is Cisco抯 standard method of providing high network availability by providing first-hop redundancy for IP hosts on an IEEE 802 LAN configured with a default gateway IP address. HSRP routes IP traffic without relying on the availability of any single router. It enables a set of router interfaces to work together to present the appearance of a single virtual router or default gateway to the hosts on a LAN. When HSRP is configured on a network or segment, it provides a virtual Media Access Control (MAC) address and an IP address that is shared among a group of configured routers. HSRP allows two or more HSRP-configured routers to use the MAC address and IP network address of a virtual router. The virtual router does not exist; it represents the common target for routers that are configured to provide backup to each other. One of the routers is selected to be the active router and another to be the standby router, which assumes control of the group MAC address and IP address should the designated active router fail. Note: Routers in an HSRP group can be any router interface that supports HSRP, including Catalyst 3550 routed ports and switch virtual interfaces (SVIs).
Multicasting
The Cisco IOS software supports these protocols to implement IP multicast routing:
