[FROG] OSPF Fast Convergence (RFC6976)?

Hi all,

I came across

``Framework for Loop-Free Convergence – Using the Ordered Forwarding
Information Base (oFIB) Approach'' [0]

which may be a phantastic remedy to a problem that occurs from time to
time in a network I maintain: Even restarting a single OSPF process (on
a group of about 20 routers in that area) causes trouble in
forwarding/routing of 60.000+ TCP streams that traverse that area.

(EIGRP is said to be immune against that because of explicit termination
of the diffusing computations.)

AFAICS it's not implemented yet in any free routing suite – are there
any plans of doing so (in FRR)?

Best regards,

Timo
