Configuring Smart-discover

Configuring Smart-discover

Context

Before Smart-discover is configured, when the neighbor status of the router changes or the DR/BDR on the multi-access network (broadcast or NBMA network) changes, the router does not send Hello packets to its neighbor until the Hello timer expires. This slows down the establishment of neighbor relationships between devices. After Smart-discover is configured, when the neighbor relationship status of the router changes or the DR/BDR on the multi-access network (broadcast or NBMA network) changes, the router can send Hello packets to its neighbor immediately without waiting for the expiration of the Hello timer. This speeds up the establishment of neighbor relationships and thus implements fast convergence of OSPF networks.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The OSPF interface view is displayed.

  3. Run ospf smart-discover

    Smart-discover is configured on the interface.
