    Configuring DVMRP Summary Addresses

    This section describes how you can reenable the router to summarize routes automatically for a specific interface and use it to advertise DVMRP summary addresses on an interface.

    To reenable the router to summarize routes automatically for this interface:

    • Issue the ip dvmrp auto-summary command in Interface Configuration mode..
      host1:boston(config-if)#ip dvmrp auto-summary

      By default, automatic summarization is enabled. Use the no version to disable automatic summarization for this interface.

    To advertise DVMRP summary addresses on an interface:

    • Issue the ip dvmrp summary-address command in Interface Configuration mode.
      host1:boston(config-if)#ip dvmrp summary-address 192.48.1.2 255.255.255.0 metric 1

      By default, an interface advertises only summary addresses generated by automatic summarization. If you configure multiple overlapping summary addresses on an interface, the one with the shortest mask takes preference. Use the metric keyword to specify a DVMRP metric (hop count); the default metric value is 1. Use the no version to stop advertising a summary address on the interface.
