That's what I did. I set up three routers in a chain, with a hub in
between two of the routers, and a PC connected in running a packet
analysis program. I could verify that when encryption was not active,
the packets that were passing were clear text, and when the keys were
exchanged and IPSec was active, the packets were encrypted. Not
difficult to do, and I found it quite interesting as it was the first
time I had worked with encryption.

If you wanted to be absolutely sure, you could link the routers
together on ethernet and use a pc based analyzer to look at the
traffic...

I've set up a basic DES encryption between tow routers, and have
checked the connection. It appears to be up.
r2#sho crypto cisco connections
Connection Table
PE UPE Conn_id New_id Algorithm Time
12.12.12.1 11.11.11.1 1 0 DES_56_CFB8 Mar 01 1993
00:18:37
flags:TIME_KEYS ACL: 101
I am able toping between the two routers. I've looked in the IOS
but cannot find a way to make sure that my access list is working. In
other words, I have a serial link beween r1 and r2. r1 is 10.10.10.1
and r2 is 10.10.10.2. I've created a loopback on each. On r1,its
11.11.11.1 and r2 its 12.12.12.1. My access list allows 11.11.11.1 to
12.12.12.1 on r1, and the reverse on r2.
How do I know that my pings (they work) are getting encrypted
beside logging on the access-list? The log shows the access list
getting hit, so am I to a assume its encrypted?
