Hi all. I was caught up in a vpn issue and did debug (debug cry ipsec). I discovered that there was a proxy mismatch. I have gone through different articles and docs but never read anywhere that routers in ipsec negotiation also exchange their crypto acls ?? is it correct ? Because i used a combination of mask on one router and could see exactly that mask in debug on other router. It seems that routers also exchange crypto acls also ?
Kindly confirm this point and if possible any cisco doc that addresses this issue also
