Hi,
I am working on a CCIEbootcamp Lab 8 . however, I have a problem
in the X25 and ISDN backup. I found that there is a problem in the
ISDN line always up. This may due to the DSLW I setup. and I am now
solving on this. However, I found there is a strange trace 1
173.20.201.5 !A * !A which is the trace from the R1 to the R5
through the X25 network.
Does any know what is this mean ?
I am ping from R1 to R5 173.20.201.5.
