Configuring the Register Message Rate Limit for PIM

The maximum number of register packets sent or received per second by a device can be configured.
Complete the following steps to configure the register message rate limit to 20 packets per second, changing it from the default of 1 packet per second. This rate is applicable to register messages from all sources. This rate is applied to all sources that are permitted by the accept-register filter that is used to block unauthorized sources or groups.
  1. Enter global configuration mode.
    device# configure terminal
  2. Enable PIM globally.
    device(config)# router pim
  3. Set the register rate limit to 20 packets per second.
    device(config-pim-router)# register-rate-limit 20

The following example sets the register message rate limit to 20 packets per second.

device# configure terminal
device(config)# router pim
device(config-pim-router)# register-rate-limit 20

The following example restores the register message rate limit to the default of 1 packet per second..

device# configure terminal
device(config)# router pim
device(config-pim-router)# no register-rate-limit
