Assuming you're using LAN cards, you may want to see if you can make
router links as routed rather than SVI interfaces. Though routed
interfaces are implemented internally as VLANs, presentations I saw from
Cisco claim that this:
I prefer to use BFD personally. Link failure detection without BFD will
be slow no matter what you do. FRR doesn't gain you much if it takes
you several seconds to realize that a link dropped.
Seconds? Wow. I'm curious - under what circumstances are you seeing such
length link-loss detection times?
