Description
Minimum traffic rate required to advertise Source-Active route (1 to 1000000 bits per second), set on the ingress PEs.
Use the command, for example, to ensure that the egress PEs only receive Source-Active A-D route advertisements from ingress PEs that are receiving traffic at or above a minimum rate, regardless of how many ingress PEs there may be. Only one of the ingress PEs is chosen as the upstream multicast hop (UMH). Traffic flow continues because the egress PE removes its Type 7 advertisements to the old UMH and re-advertises a Type 7 to the new UMH.
The min-rate command works by polling traffic stats to determine the traffic
rate of each flow on the ingress PE. Rather than advertising the Source-Active A-D route
immediately upon learning of the S,G, the ingress PE waits until the traffic rate reaches
the threshold set for min-rate before sending the Source-Active A-D route. If the
rate then drops below the threshold, the Source-Active A-D route is withdrawn.
To verify that the value is set as expected, you can check whether the Type 5 (Source-Active
route) has been advertised using the show route table vrf.mvpn.0 command. It may take several minutes before you can see the changes in the Source-Active
A-D route advertisement after making changes to the min-rate.
