Description (partial)


ATM and TDM pseudowire path switch initiated by BFD takes more than
one second to re-route on MWR 2941.


- An interior gateway routing protocol such as OSPF or IS-IS is used for
  pseudowire IP route selection.
- Bidirectional Forwarding Detection (BFD) is being used by the routing
  protocol to detect pseudowire path failures.
- The pseudowire destination IP address is multiple IP hops away from
  the MWR 2941.
- The path failure results in a route that goes out a different interface
  than the previous path used.
- There are more than 200 routes in the IP routing table that are affected
  by the path failure that changes the pseudowire path.
