I suspect it's not working over AREA 24 because R6 is not in area 24. Don't both endpoints of the sham-link need to be in the same area?

I know the example is a bit extreem but i wanted to force as may problems in the lab as possible --------MPLS------------ | | | | R6 (PE) R2 (PE) | | | | (AREA 56) (AREA 24) | | | | R5 R4 | | | | (AREA 56) (AREA 24) | | | | R7 R8 | | | | (AREA 0) (AREA 0) | | | | R1 R9 | | | | -------(AREA 19)-------- (Backdoor Link) Here is what i have done 1.) Virtual Link AREA 19 Between R1 and R9 2.) Virtual Link AREA 56 Between R7-R5-R6 3.) Virtual Link Area 24 Between R8-R4-R2 4.) Sham Link Area 24 Between R2 and R6 If i put the sham link into area 0 all is good If i put the sham link into area 24 all routes from other side show up as E2 routes I tried making a virtual link as well in area 24 between R2 and R6 (over the sham link) but that did nothing (I didnt expect it to but it was worth a shot) Where is my logic wrong?
