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

19.3.2.4 ip 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

19.3.3 Typical 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.
