Specifying Redundant Flow Sources

To specify redundant (backup) sources for flows identified by a flow map, include the redundant-sources statement:




redundant-sources [ addresses ];

You can include this statement at the following hierarchy levels:

[edit routing-options multicast flow-map flow-map-name]
[edit logical-systems logical-system-name routing-options multicast flow-map flow-map-name]
[edit logical-systems logical-system-name routing-instances routing-instance-name routing-options multicast flow-map flow-map-name]
[edit routing-instances routing-instance-name routing-options multicast flow-map flow-map-name]

Outbound interfaces that are admitted for one of the forwarding entries are automatically admitted for any other entries identified by the redundant source configuration.

In the following example, forwarding entries (10.11.11.11, g1) and (10.11.11.12, g1) match the flow map flowMap1. In this case, if a particular outbound interface is admitted for entry (10.11.11.11, g1), it is automatically admitted for entry (10.11.11.12, g1), even if there is no longer enough remaining bandwidth available after creating entry (10.11.11.11, g1). The interface is added because only one of the two sources can send traffic at any time.



[edit routing-options]
multicast {


flow-map flowMap1 {
redundant-sources [ 10.11.11.11 10.11.11.12 ];
}


}
