Here is the question and answer: However, i am unable to verify the
solution.
I think i am perhaps misunderstanding the question.
I was hoping to see this work if i use tftp.
The BB2 router is reporting some problems and it is not stable. Configure R4
to save a core dump via FTP in case BB2 fails or crashes. Consider the FTP
username CISCO, password CCIE, FTP server IP address 140.200.100.200 (this
lan is not a transport path. It is isolated), and filename dumpfile. Use
passive mode also.
Solution
ip ftp soruce-interface Ethernet0/0
ip ftp username CISCO
ip ftp password CCIE
!
!
exception protocol ftp
exception dump 140.200.10.200
exception core-file dumpfile
