I went through the encryption bit a while back and like you I wanted
to be 100% sure that packets were encrypted. So I put an Ethernet link
somewhere in the middle and put a sniffer on it.
This is also useful to see the difference between the methods i.e
encrypting payloads only or both payload & header etc...

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?
