BOOTP/DHCP Relay Agent
The switch BootP/DHCP Relay Agent feature relays BootP and DHCP 
messages between DHCP clients and DHCP servers that are located in 
different IP subnets. 
For information about configuring the BootP/DHCP Relay agent, see 
"Configuring L2 and L3 Relay Features" on page 907.
IP Helper and UDP Relay
The IP Helper and UDP Relay features provide the ability to relay various 
protocols to servers on a different subnet.
For information about configuring the IP helper and UDP relay features, see 
"Configuring L2 and L3 Relay Features" on page 907.
Routing Information Protocol
Routing Information Protocol (RIP), like OSPF, is an IGP used within an 
autonomous Internet system. RIP is an IGP that is designed to work with 
moderate-size networks.
For information about configuring RIP, see "Configuring RIP" on page 1019.
Router Discovery
For each interface, you can configure the Router Discovery Protocol (RDP) to 
transmit router advertisements. These advertisements inform hosts on the 
local network about the presence of the router.
For information about configuring router discovery, see "Configuring IP 
Routing" on page 883.
Routing Table
The routing table displays information about the routes that have been 
dynamically learned. You can configure static and default routes and route 
preferences. A separate table shows the routes that have been manually 
configured.
For information about viewing the routing table, see "Configuring IP 
Routing" on page 883.
