how do you switch between DLCIs on your FR switch?
on R2 you have DLCI 203 and 204 both of which have to be switched to 302
on one side and to 402 on the other.
why to have two sub-interfaces sharing the same /24 subnet? Secondary IP
no the physical interface with proper mapping would probably give you
what you need...
