Description

Configure segmentation of inter-region on an ingress PE router or transit area boundary routers (ABRs) by specifying only a fan-out factor or threshold rate or both. The inter-region segmentation allows the PE router to signal segmented S-PMSI A-D routes. If the segmentation is based on the threshold, then the MVPN starts migrating the traffic flow to a segmented S-PMSI when the threshold configured for the selective tunnel reaches the threshold rate. The threshold value can be configured for S-PMSI with LDP-P2MP, IR, and RSVP-TE tunnel types. If the fan-out value is configured, then the traffic flow is moved to segmented S-PMSI when the number of leaf A-D routes per S-PMSI meets the configured fan-out value. The fan-out value can be configured for wildcard S-PMSI, and S-PMSI.

If both threshold and fan-out values are set for S-PMSI with LDP-P2MP, IR, and RSVP-TE tunnel types, then the traffic flow to the segmented inter-region happens only when the traffic rate multiplied by the number of leaf A-D routes exceeds the threshold value.

Options

fan-out fan-out-value

Specify the number of remote leaf A-D route values for fan-out. Once the number of leaf A-D routes per S-PMSI meets the configured fan-out value, the inter-region segmentation is triggered and the traffic flow is directed to segmented S-PMSI.

  • Range: 1 through 10000

threshold rate-value

Specify the data threshold rate to trigger inter-region segmentation.

Note:

This option is available only at the following hierarchy levels:
