(Optional) Setting the TTL Threshold for Forwarding an SA Message Containing a Multicast Data Packet

After receiving a source active (SA) message encapsulated with a multicast data packet, an MSDP peer forwards the SA message to a specified remote MSDP peer only when the TTL value of the multicast packet is greater than the configured TTL threshold.

Context

Perform the following steps on the router configured with an MSDP peer:

If the configuration is not performed, default parameter values are used.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run msdp [ vpn-instance vpn-instance-name ]

    The MSDP view is displayed.

  3. Run peer peer-address minimum-ttl ttl

    A TTL threshold is set for multicast data packets.

    After receiving an SA message containing a multicast data packet, an MSDP peer forwards the SA message to a specified remote MSDP peer only when the TTL value of the multicast packet is greater than the configured TTL threshold.

    The parameter meanings as follows:

    • peer-address: specifies the IP address of a remote MSDP peer.

    • ttl: specifies the value of the TTL threshold. The default value is 0.

  4. Run commit

    The configuration is committed.
