VPN and rate limit

[brlance]

If a committed access rate is configured on a WAN interface and the limit is exceeded and packets are set to drop what happens to a vpn session? Is the connection terminated or just how would it handle dropped packets?

The tunnel is not dropped, but instead the packets that were encrypted will get dropped. Usually higher layer protocols capable of handling retransmissions will take care of the dropped packets. Same reason why Voice applications does not recommend CAR (rate-limitting) as a effective means for throttling bandwidth, as voice cannot handle dropped packets..
