We're having discussion of changing BGP timers rather than using BFD and I'd 
like to ask for your operational experiences on this.

We have downstream BGP customers physically attaching to an L2/L3 switch that 
doesn't do BGP.  So, we logical pipe them through MPLS to a router that can 
terminate the BGP session.  The logical pipe never goes down, so the only thing 
that would cause the customer's session to go down in the event of a physical 
layer problem is the BGP timer.

This is not acceptable, so I have been using BFD to time out the BGP session.  
However, we have limitations on the BFD pps and folks here are wanting to 
change the BGP timers instead.

What're your experiences regarding this?
