Thanks for finding that in the doc for me. I'll be back in the lab today so
I should be able to test it and let everyone know.

Subject: RE: DLSW local peer cost vs. remote peer cost
To add to my last reply....it's under all 12.x docs too...it
consistently appears under "dlsw remote-peer frame-relay" and dlsw
remote-peer interface", so I ASSuME it applies to all remote statements
where the cost parameter is usable....hope to test it this week-end if
not confirmed by someone else
