I have question about improving ospf convergence time within a test mpls core network. The network consist of 10-Gig ethernet and Optical connections.
There are a few configuration options that can be combined together to achieve sub-second ospf convergence.
I am looking at these options:
2. OSPF Fast-hellos
3. timers throttle spf/lsa
5. RSVP Hellos
I am mainly focussing on first three configuration options to achieve quick failure detection and convergence (1 s or less).
I am trying avoid FRR for supportability issues and ease of admin overhead.
I have read through several docs on BFD, Fast-hello and timers throttle spf/lsa configuration. I do believe it is possible to achieve convergence to this level, if not exactly in msec.
Can I achieve fast ospf convergence with a combination of fast-hellos, bfd, and timer throttle ??
Any ideas/suggestions would be appreciated!!!
