HI there David,
I know ISDN is out of CCIE just that i have a project coming up so i wanted
to practice. Anyway i have a vconsole simulator and i am using "isdn
switch-type basic-net3", yes the number i am using is pretty long i think 10
digit but the issue is i am getting this error on only one router (R2), on
the other router (R1) no errors at all and when i switch the ports from the
simulator the errors starts coming in (R1) so it seems to be a simulator
issue but i dont understand what.....any other ideas?
Thanks
Aamir
