Additional IP Protocols
There are several additional IP-related protocols that may 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 18-12.
• Virtual Router Redundancy Protocol (VRRP)—Used to back up routers. For more information, see
Chapter 23, “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 18-28.
• Router Discovery Protocol (RDP)—Used to advertise and discover routers on the LAN. For more
information, see Chapter 21, “Configuring RDP.”
• Multicast Services—Includes IP multicast switching (IPMS). For more information, see Chapter 32,
“Configuring IP Multicast Switching.”
