Here is the setup
R5
/ \
ISDN Frame
\ /
R6
Area 0 is over both ISDN and Frame.
I seem to missing something here. I have just basic ISDN connectivity setup
between R5 and R6 using chap. Nothing fancy on the ISDN side.
When OSPF establishes the adjacency between R5 and R6 it is using the ISDN
connection. Which is fine the ISDN is 128k and the Frame is 64k. No neighbor
relationship between R5 and R6 is happening across the frame at all.
I am configure, on R6, for the ISDN to be backup interface to the Frame
connection. The ISDN link goes in standby mode but OSPF looses adjacency with
R5 on the BRI but never establishes a neighbor relationship with R5 over the
frame. I end up losing network connectivity to the networks beyond R5 even
though the frame is up. I have cleared the OSPF process and it doesn't
re-establish with R5.
I am missing a fundamental concept here, I think.
