Accton Technology ES4710BD manual Ip pim query-interval, Typical PIM-DM Scenario

ES4710BD 10 Slots L2/L3/L4 Chassis Switch

Command: ip pim dense-mode

no ip pim dense-mode

Function: Enables PIM-DM protocol on the interface; the “no ip pim dense-mode” command disables PIM-DM protocol on the interface.

Parameters: N/A.

Default: PIM-DM protocol is disabled by default.

Command mode: Interface Mode

Usage Guide:

Example: Enabling PIM-DM protocol on interface vlan1.

Switch (Config)#interface vlan 1

Switch(Config-If-Vlan1)#ip pim dense-mode

19.3.2.4ip pim query-interval

Command: ip pim query-interval <query interval> no ip pim query-interval

Function: Sets interval for sending PIM-DM HELLO packets in the interface; the “no ip pim query-interval” command restores the default setting.

Parameters: <query interval> is the interval for sending PIM-DM HELLO packets, ranging from 1 to 18724s.

Default: The default interval for sending PIM-DM HELLO is 10 seconds.econds.

Command mode: Interface Mode

Usage Guide: The HELLO message enables PIM-DM switches to locate each other and establish the neighborhood. PIM-DM switches claim their existence by sending HELLO message to their neighbors. If no HELLO message from a neighbor is received in a specified period, that neighbor is considered to be lost. This time must be no greater than the neighbor timeout time.

Example: Configuring PIM-DM HELLO interval on interface vlan1. Switch (Config)#interface vlan1 Switch(Config-If-Vlan1)#ip pim query-interval 20

19.3.3Typical PIM-DM Scenario

As shown in the figure below, the Ethernet interfaces of SwitchA and SwitchB are added to the appropriate vlan, and PIM-DM protocol is enabled on each vlan interface.
