Hi,
 
Yes, I've tested it and it worked okay.
 
The only problem is that you need to do some spoofing to get around the delay of the
route being installed in the VRF (bgp scan-time is one way, but not ideal, playing with
a floating static and a dummy loopback is a better way)...Robert R posted a sample
config to this forum for getting around this a little while ago.
 
Could you please enlighten me why you think it might be different if dialing into the same
PE, versus a different one....perhaps I've missed something?
 
Cheers.

Hi ,
 
Has anybody tested an ISDN fallback to the PE for a VPN customer leased line on the same PE. Does the mpls vpn work on the isdn fallback .
 
Thx&Rgds
