Syntax Description

Command Modes Interface configuration
Command History
Usage Guidelines Use this command to configure the frequency of PIM neighbor discovery messages. By default these
messages are sent once every 30 seconds. In PIM Version 1 (PIMv1), these messages are referred to as
PIM query messages; in PIM Version 2 (PIMv2), these messages are referred to as PIM hello messages.
By default, routers run PIMv2 and send PIM hello messages. A router changes (auto-fallback) to PIMv1
and sends PIM query messages if it detects a neighboring router that only supports PIMv1. As soon as
that neighboring PIMv1 router is removed from the network, the router reverts to PIMv2.
Note A router can be configured to exclusively use PIMv1 on an interface with the ip pim version 1
command.
period The number of seconds or milliseconds (ms) that can be configured for the
PIM hello (query) interval. The range is from 1 to 65535.
msec (Optional) Specifies that the interval configured for the period argument be
interpreted in milliseconds. If the msec keyword is not used along with the
period argument, the interval range is assumed to be in seconds.
