How about just using the ethernet addresses?
R1(config)dlsw local-peer peer-id 11.1.1.1
R1 (config) dlsw remote-peer 0 22.2.2.2
Frame goes down, ISDN comes up, IGP reconverges, dlsw circuit comes back
up across ISDN link.
Or did I miss something - aside from assuming your ethernets are in your
IGP?
