We are facing some problem with VPN tunnel from router to router.
We are forming tunnel from R1 to R2 on loopback address. It was working ok and suddenly it is showing status as down.
I am attaching debug cry ipsec output here in text mode.
Here we suspect :
Feb 26 11:02:40.779: ISAKMP:(0:0:N/A:0):Encryption algorithm offered does not match policy!
Coincidently it was working and suddenly gone down.
Thanks and advance
