In dynamips I created a GRE tunnel over a VPN between 2 routers over a simulated Internet connection and it works great. I'm able to create EIGRP neighborships, exchange routes and ping across it all day without losing a ping.
Next, I created a l2TPv3 tunnel across the VPN to have a VLAN existing on both sides. Shortly after sending traffic across the l2TPv3 tunnel, the EIGRP neighborship fails, the tunnel breakes, and I start losing pings. The tunnel will then re-establish and the fail again and again and my pings will fail and succeed for a bit then fail.
%CRYPTO-4-PKT_REPLAY_ERR replay check failed
From looking around for work-arounds I've increased the crypto ipsec security-association replay window-size to 1028 and used encryption only on both sides of the VPN but, still the tunnel breaks.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
