We have found that VPN tunnel goes down when link on which is it formed is having lots of errors. We are using pre-sahred key to form IPSec between two routers on point to poin tlink. Why it happends that when link is having lots of errors and CRC's IPSec tunnel is not formed. Packets hitting the tunnel never reaches the destination. But at the same time application using https:// works well. The moment we remove crypto ( ipsec commands ) from both routers we could get connectivity. Are errors responsible for IPSsec tunnel formation and tearing it down.

Please share experience!!

Thankx in advance

Just asking, are you using a provisioning tool to create all your IPSec configurations?
