(Optional) Setting the Values of the Hello Timer and Fail Timer in an RRPP Domain

(Optional) Setting the Values of the Hello Timer and Fail Timer in an RRPP Domain

Context

The Hello timer and Fail timer are used when the master node sends and receives RRPP packets. The value of the Hello timer specifies the interval at which the master node sends Hello packets from the primary interface. The value of the Fail timer specifies the maximum delay in which the primary interface on the master node sends a Hello packet and the secondary interface receives the Hello packet.

You only need to set the values of the Hello timer and Fail timer on the master node in an RRPP domain.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run rrpp domain domain-id

    The RRPP domain view is displayed.

  3. Run timer hello-timer hello-value fail-timer fail-value

    The values of the Hello timer and the Fail timer in an RRPP domain are set.

    The value of the Fail timer must be no smaller than three times the value of the Hello timer.

    By default, the value of the Hello timer on an edge node is half of the value of the Hello timer on the master node of the major ring.

    The values of both the Hello timer and Fail timer must be set the same on each node in an RRPP domain; otherwise, edge interfaces on the edge nodes may be unstable.

    It is recommended that the value of the Fail timer be configured based on the actual networking. If the value of the Fail timer is incorrect, for example, the value is too small, loops may occur.
