Carlos,
You do not need "bandwidth" on either routers; you could add "ip ospf cost
9999" to achieve what you intended, but that is not necessary since the ISDN
link is in a stub area.
If the primary connection is over Serial link, remove "passive-int ser 0"
from R6 routing process so R3 and R6 exchange routing updates.
Your BRI is in Area 1, and you have the message-digest key on the interface.
You should remove authentication from the dialer interfaces, or add "area
1 authentication message-digest" to the routing process on both routers (as
well as the other routers in area 1).
I don't think you need this, but would try it if you can't get the multilink
working: "dialer string 5554000" on R3 and "dialer string 5553000" on R6.
Carlos, what is your workaround?
Thanks, Kym
