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.
For fast external fallover, your physical interface has to go down. Inside your network you could use BGP fast fallover (which drops BGP session after the IGP route to the neighbor is lost), details are here: http://www.nil.com/ipcorner/DesigningBGPNetworks/ Fast fallover with EBGP multihop is described here: http://wiki.nil.com/EBGP_load_balancing_with_EBGP_session_between_loopback_i nterfaces Ivan http://www.ioshints.info/about http://blog.ioshints.info/
