Configuring Smart-discover

Context

If the neighbor status of a switch changes or the DR/BDR on a multi-access network (broadcast or NBMA network) changes before Smart-discover is configured, the switch does not send Hello packets to its neighbor until the Hello timer expires. This slows down the establishment of neighbor relationships between devices. To resolve this problem, you can configure Smart-discover to allow the switch to send Hello packets to its neighbor immediately without waiting for the expiration of the Hello timer.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The OSPF interface view is displayed.

  3. (Optional) On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

    Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.

  4. Run ospf smart-discover

    Smart-discover is configured on the interface.
