One or more ipsec tunnels can terminate on a single interface.
Cisco iwan front door vrf.
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.
This means a single router can have multiple separated routing table and each one is completely independent due to its independency it also allows the usage of overlapping ip address cisco ios router supports vrf by default.
Ciently by using all available wan bandwidth.
Application optimization cisco application visibility and control avc and cisco wide area application services waas provide applica tion performance visibility and optimization over the wan.
The realized savings from iwan not only pays for the infrastructure upgrades but also frees resources for business innovation.
Cisco s validated design cvd for iwan suggests the use of front door vrfs in an iwan environment.
Virtual routing and forwarding or vrf is a technology that supports multiple routing instance inside a single router or layer 3 switch.
The intended audience is a technical decision maker who wants to compare cisco s wide area network wan offerings and learn more about the best prac.
