Additional IP Protocols
There are several additional IP-related protocols that can be used with IP forwarding. These protocols are
included as part of the base code.
• Address Resolution Protocol (ARP)—Used to match the IP address of a device with its physical
(MAC) address. For more information, see “Configuring Address Resolution Protocol (ARP)” on
page 11-12.
• Virtual Router Redundancy Protocol (VRRP)—Used to back up routers. For more information, see
Chapter 18, “Configuring VRRP.”
• Internet Control Message Protocol (ICMP)—Specifies the generation of error messages, test packets,
and informational messages related to IP. ICMP supports the ping command used to determine if hosts
are online. For more information, see “Internet Control Message Protocol (ICMP)” on page 11-29.
• Multicast Services—Includes IP multicast switching (IPMS). For more information, see Chapter 20,
“Configuring IP Multicast Switching.”
