Advanced Configuration and Management Guide

8.If you are configuring an IP Tunnel, enter the IP address of the destination interface, the end point of the IP Tunnel, in the Remote Address field. IP tunneling must also be enabled and defined on the destination router interface as well.

NOTE: The Remote Address field applies only to tunnel interfaces, not to sub-net interfaces.

9.Modify the time to live threshold (TTL) if necessary. The TTL defines the minimum value required in a packet in order for the packet to be forwarded out the interface.

NOTE: For example, if the TTL for an interface is set at 10, it means that only those packets with a TTL value of 10 or more will be forwarded. Likewise, if an interface is configured with a TTL Threshold value of 1, all packets received on that interface will be forwarded. Possible values are 1 – 64. The default value is 1.

10.Click the Add button to save the change to the device’s running-config file.

11.Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change to the startup-config file on the device’s flash memory.

12.Click on the plus sign next to Command in the tree view to list the command options.

13.Select the Reload link and select Yes when prompted to reload the software. You must reload after enabling PIM to place the change into effect. If PIM was already enabled when you added the interface, you do not need to reload.

Modifying PIM Global Parameters

PIM global parameters come with preset values. The defaults work well in most networks, but you can modify the following parameters if you need to:

•Neighbor timeout

•Hello timer

•Prune timer

•Graft retransmit timer

•Inactivity timer

Modifying Neighbor Timeout

Neighbor timeout is the interval after which a PIM routing switch will consider a neighbor to be absent. Absence of PIM hello messages from a neighboring router indicates that a neighbor is not present.

The default value is 180 seconds.

USING THE CLI

To apply a PIM neighbor timeout value of 360 seconds to all ports on the routing switch operating with PIM, enter the following:

HP9300(config)# router pim

HP9300(config-pim-router)# nbr-timeout 360

Syntax: nbr-timeout <60-8000>

The default is 180 seconds.

USING THE WEB MANAGEMENT INTERFACE

1.Log on to the device using a valid user name and password for read-write access.

2.Click on the plus sign next to Configure in the tree view to expand the list of configuration options.

3.Click on the plus sign next to PIM in the tree view to expand the list of PIM option links.

4.Click on the General link to display the PIM configuration panel, as shown in the following example.
