Deploying the cisco intelligent wan this guide focuses on how to deploy the base cisco intelligent wan iwan. The outer encapsulated packet belongs to one vrf domain called the front door vrf fvrf while the inner protected ip packet belongs to another domain called the inside vrf ivrf. The advanced features are covered in the iwan advanced deployment series of guides. Stated another way the local endpoint of the ipsec tunnel belongs to the fvrf while the source and destination addresses of the inside packet belong to the ivrf.

Order to deliver the best quality experience. The fvrf of all these tunnels is the same and is set to the vrf that is confi gured on that interface.
