bbell22,
On the production router, enter this (remote host is the TFTP server) -
Lab-B-Boston#copy startup-config tftp
Address or name of remote host []? 192.168.100.6
Destination filename [lab-b-boston-confg]?
!!
2356 bytes copied in 0.297 secs (7933 bytes/sec)
Lab-B-Boston#
Config files are very small and transfer takes very little time or resources from the production router.
Then you have the complete config file on your TFTP for you to later download to your lab router.
Hope this helps!
