Asante Technologies 35516 Configuring Icmp Router Discovery Protocol Irdp, Enable Irdp Processing

The following commands are available under EXEC or Enable mode:

Command	Purpose
show vrrp [brief VRID]	Displays a brief or detailed status of one or all
	VRRP VRID groups on the router.
show vrrp interface IFNAME [brief]	Displays the VRRP groups and their status on a
	specified interface.
debug ip vrrp	This command helps to debug VRRP operation. If
	this is enabled, then VRRP displays the debug
	messages onto the console.

5.9 Configuring ICMP Router Discovery Protocol (IRDP)

When IP routing is disabled, you can configure router discovery. The ICMP Router Discovery Protocol (IRDP) allows the router to dynamically learn about routes to other networks. When operating as a client, router discovery packets are generated. When operating as a host, router discovery packets are received. The IC35516 IRDP implementation fully conforms to the router discovery protocol outlined in RFC 1256.

The server/client implementation of router discovery does not actually examine or store the full routing tables sent by routing devices, it merely keeps track of which systems are sending such data.

5.9.1 Enable IRDP Processing

The only required task for configuring IRDP routing on a specified interface is to enable IRDP processing on that interface. Use the following command in interface configuration mode.

Command

ip irdp

Purpose

Enable IRDP processing on an interface.

5.9.2 Change IRDP Parameters

When IRDP processing is enabled, the default parameters will apply. The user may change any of the following default parameters. Use the following commands in interface configuration mode.

Command	Purpose
ip irdp multicast	Send IRDP advertisements to the all-systems
	multicast address (224.0.0.1) on a specified
	interface.
ip irdp holdtime seconds	Set the IRDP period for which advertisements are
	valid.
ip irdp maxadvertinterval	Set the IRDP maximum interval between
seconds	advertisements.
ip irdp minadvertinterval	Set the IRDP minimum interval between
seconds	advertisements.
Ip irdp preference number	Set a device’s IRDP preference level.

5.10 Monitoring and Maintaining the Network

You can monitor the network by displaying specific statistics such as the contents of IP routing tables, and databases. The resulting information can be used to determine resource utilization and to solve network problems. You also can display information about node reach-ability and discover the routing path that your device's packets are taking through the network.
