Hi people, I've been struggling with this one for hours now, please can somone put me out of my misery??

If I configure dlsw+ direct encapsulation between two routers both using physical interfaces everything works ok. If I then change one end to use a frame-relay sub-interface I can't get it to work.

This works......

R1:

bridge 1 proto ieee
dlsw local peer 20.1.1.1
dlsw remote 0 frame int s0/0 102 pass-thru
dlsw bridge 1

int e0
        bridge-group 1

s0/0
        encaps frame
        no frame inv
        ip add 20.1.12.1 255.255.255.0
        frame map ip 20.1.12.1 102
        frame map ip 20.1.12.2 102 broad
        frame map dlsw 102 broad

R2:

bridge 1 proto ieee
dlsw local peer 20.1.2.2
dlsw remote 0 frame int s0/0 201 pass-thru
dlsw bridge 1

int e0
        bridge-group 1

s0/0
        encaps frame
        no frame inv
        ip add 20.1.12.2 255.255.255.0
        frame map ip 20.1.12.2 201
        frame map ip 20.1.12.1 201 broad
        frame map dlsw 201 broad

IF I THEN CHANGE R2 TO THE FOLLOWING, PEERING WILL NOT COME UP......

R2:

bridge 1 proto ieee
dlsw local peer 20.1.2.2
dlsw remote 0 frame int s0/0.12 201 pass-thru
dlsw bridge 1

int e0
        bridge-group 1

s0/0
        encaps frame
        no frame inv
s0/0.12
        ip add 20.1.12.2 255.255.255.0
        frame map ip 20.1.12.2 201
        frame map ip 20.1.12.1 201 broad
        frame map dlsw 201 broad

Any ideas or advice would be much appreciated.

Chris.
