[dev] EIGRP

The last couple years I have been working on a side project to implement a fully functional and tested version of EIGRP based on FRR release 5.0. That work is largely complete and I would like to share with the community but it will likely require significant grooming to match the coding style requirements and stage the multiple merge requests required integrate it with the dev code-base. Unfortunately I don't have time to do that.

This implementation behaves very well in complex Cisco-based networks with only one 'on-the-wire' deviation from Cisco's behavior (sending individual REPLY messages for each prefix in a bulk QUERY instead of bundling them, which only results in slightly more traffic and processor usage and doesn't affect network the topology). The latest version includes clean Stuck-in-active behavior as well. Current work is adding BFD to EIGRP using the 5.0 OSPF BFD implementation as a pony.

I have two questions:

  1.  Are there any defects in the 5.0 implementation of BFD that I should be aware of and/or backport BFD fixes from 7.2?
  2.  Is there any interest in including EIGRP in the full FRR feature set?
