Configuring ICMP errors

You can control whether the router sends Internet Control Message Protocol (ICMP) error
messages. The router sends an ICMP error message to the source of a packet if the router
rejects the packet. Use the following commands to configure ICMP errors:
Use the ip icmp-errors command to set ICMP error messages to ON. Use the no form
●
of this command to set ICMP error messages to OFF.
Use the show ip icmp command to display the status (enabled or disabled) of ICMP
●
error messages.

RIP overview
The Routing Information Protocol (RIP) enables routers to compute the path that an IP packet
should follow. Routers exchange routing information using RIP to determine routes that other
routers are connected to. OSPF is a newer protocol that serves a similar purpose. For more
information about OSPF, see
You can configure route redistribution between OSPF, RIP, and static routes. With route
redistribution, you can configure the G250/G350 to redistribute routes learned from one protocol
into the domain of the other routing protocol. For more information, see
page 351.
RIP is a distance vector protocol. The router decides which path to use on distance or the
number of intermediate hops. In order for this protocol to work correctly, all the routers, and
possibly the nodes, need to gather information on how to reach each destination in the Internet.
