Configuring the routerConfiguring ICMP errorsYou can control whether the router sends Internet Control Message Protocol (ICMP) errormessages. The router sends an ICMP error message to the source of a packet if the routerrejects 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 formof this command to set ICMP error messages to OFF.Use the show ip icmp command to display the status (enabled or disabled) of ICMPerror messages.Configuring RIPThis section provides information about configuring RIP parameters for router interfaces andcontains the following topics:●●●●●RIP overview — an overview of the RIP protocolPreventing routing loops in RIP — instructions on how to use RIP features to preventrouting loopsRIP distribution access lists — instructions on how to configure RIP distribution accesslistsRIP limitations — a description of the limitations on the use of RIP on the G350RIP commands — a list and description of CLI commands used to configure RIPRIP overviewThe Routing Information Protocol (RIP) enables routers to compute the path that an IP packetshould follow. Routers exchange routing information using RIP to determine routes that otherrouters are connected to. OSPF is a newer protocol that serves a similar purpose. For moreinformation about OSPF, see Overview of OSPF on page 194.You can configure route redistribution between OSPF, RIP, and static routes. With routeredistribution, you can configure the G350 to redistribute routes learned from one protocol intothe domain of the other routing protocol. For more information, see Route redistribution onpage 197.RIP is a distance vector protocol. The router decides which path to use on distance or thenumber of intermediate hops. In order for this protocol to work correctly, all the routers, andpossibly the nodes, need to gather information on how to reach each destination in the Internet.190 Administration of the Avaya G350 Media Gateway
