Crypto on serial ports of Cisco routers

By morshidi.m.saufi ·
How do I setup Crypto(Encryption) on the serial interfaces of 2 Cisco routers linked directly with V.35 male and female cables with one router on operational network? Do I need to shutdown this operational router?
Thanks.

Crypto on serial ports of Cisco routers

You can set up hardware encryption buy buying additional encryptor modules to fit in the routers (depending on the model).

If you have encryption software fitted (use show version) then there are varios ways .. one can be found at http://www.cisco.com/warp/customer/707/14.html#tth_sEc5.3 (you may need a login to access this page I'm not sure)

If it's in software you'll need to reconfig the links - so the link will need to be taken down while you do this.
