What’s Not Covered: IGP & LDP

For the IGPs, will need Is IP Fast-Reroute enabled on the area? What is the local hold-down time? (This needs to be specified

per area, because it depends on expected area convergence. This should be consistent within an area.)

Etc.

For LDP will need similar MIB to this one Protected/Unprotected FECs Alternate next-hop information, including alternate label Etc.

What’s Next?

Is this grouping of related MIBs appropriate? What else would be useful to include in the IP FRR IP

MIB? Is there interest in this draft MIB?

Draft includes support for U-turn alternates. Should it include support for other candidate alternate types?

Please send comments to the list.
