RE: Multi-homed clients and BGP timers

If you want to converge a little fast than BGP holdtimes here
and the fiber link is directly between the routers, you might
look at something akin to Cisco's "bgp fast-external-fallover",
which immediately resets the session if the link layer is
reset or lost.


Also things to consider: BFD for BGP and UDLD will help identify link failures faster. (If all of your equipment 
supports it, YMMV, etc).
