IPSec tunnel doesn't work

Question

Hi,
I'm practicing a little with 2 routers CISCO 2811 and 2621. I made the basic configuration for an IPSec connection but the tunnel doesn't seem to come up. Also, I can ping each other router's external interface but I can't ping the inside network behind each one. Any Ideas? The outside interface are connected via croosover UTP cable. These are the sh run of each one:

I also tried the show crypto isakmp sa and there is nothing on the tables. Thanks for any help.

Answer 1

Under crypto map armadilloin Router 2621 =
Use the crypto ACL 102 instead of 101.
match address 102
And then clear the isakmp sa and ipsec sa
then try to ping.
