HP9300(config)# show ip dr-aggregate

Syntax: show ip dr-aggregate [<ip-addr>]

If you specify an IP address, only the entries for that destination are displayed.

Here is an example of the information displayed by this command.

HP9300(config)# show ip dr-aggregate

This example shows two entries. The prefix associated with each entry is displayed. Notice that the prefix lengths in this example are different for each entry. The software selects a prefix length long enough to make the default network route entry unambiguous, so that is does not conflict with other cache entries.

To display the entry for a specific destination, enter the destination address, as shown in the following example.

HP9300(config)# show ip dr-aggregate 207.96.7.7

This example shows the second entry from the previous example, but the entry row number is 1. The row number identifies the row number in the displayed output. In addition, notice that the Total number of cache entries field shows 2, as in the previous example. The number in this field indicates the total number of default route aggregation entries in the forwarding cache.

USING THE WEB MANAGEMENT INTERFACE

You cannot display the default-route cache entries using the Web management interface.

Clearing the Forwarding Cache Entries for Default Routes

You can clear the default route entries from the IP forwarding cache. To do so, use the following CLI method.

NOTE: This command does not affect other types of forwarding cache entries.

USING THE CLI

To clear the default-route cache entries, enter the following command from the Privileged EXEC level of the CLI:

HP9300# clear ip dr-aggregate

Syntax: clear ip dr-aggregate

USING THE WEB MANAGEMENT INTERFACE

You cannot clear the entries using the Web management interface.

Configuring IRDP

The ICMP Router Discovery Protocol (IRDP) is used by HP routing switches to advertise the IP addresses of its router interfaces to directly attached hosts. IRDP is disabled by default. You can enable the feature on a global basis or on an individual port basis.

•If you enable the feature globally, all ports use the default values for the IRDP parameters.

•If you leave the feature disabled globally but enable it on individual ports, you also can configure the IRDP parameters on an individual port basis.
