I don't know your exact senario, but bridging over frame relay should look
something like,
enet--R1 - - -FRAME SWITCH- - - R2--enet
1.1.1.1/24 1.1.1.2/24
Your config should look something like:
interface ethernet 0
ip address 1.1.1.1 255.255.255.0
!
interface serial 0
no ip address
encapsulation frame-relay
no frame inverse
frame map bridge (R2) broad
bridge-group 10
!
bridge crb
bridge 10 proto ieee

They were active until I disabled ip routing as part of the bridging
procedures.
