Hi, I have a basic IPsec configuration:RouterA(fa:10.0.0.1/24) and RouterB(10.0.0.2/24). I can ping RouterA from RouterB and vice and versa.

Please find attached RouterA and RouterB show run.

I do 'show crypto ipsec sa' and it sounds like no IPsec tunnel is being generated. What else can I do to troubleshoot this and find out what's wrong? Please find pasted the RouterA and RouterB configuration.
