I have designed lab setup for IPSEC VNP before getting it for real time deployment.
under testing Ive noticed few thing:
--lan--1841 R1-- X-cable--1841 R2 --Lan
1. my tunnel always remains in QM_IDLE state even after removing x-cable
2. I cant run dynamic routing protocol, so i used static routes, is it GRE is only solution.
3. some say that u can establish vpn using loopback interface,
can some say what is the advantage of it,
and how do i implement
