MAC address learning of Riverbed
Hi Team,
We have a setup as shown below:
Core-(1/2)->(LAN0)Riverbed <Inpath deployment>(WAN0)-->(f0) router.
|(1/1) |(MGMT)
|---------------------- |
The riverbed has one MGMT interface configured with a IP 10.1.1.4/24 which is connected to the core port 1/1 and the inpath interface has the IP 10.1.1.5/24 connected to port 1/2 of the core and the router has the IP 10.1.1.6/24
The show CDP neighbors on the core indicates that the on port 1/2 we have the router IP getting learnt and corresponding router interface is f0. But physically the port 1/2 is connected one of the interfaces of the riverbed (LAN0) and WAN0 of the RB is connected to the router f0.
My query: Ideally, since port 1/2 of core is physically connected to LAN0 of the riverbed, why does the CDP neighbor reflect as the router.
My research on the same indicates that the in the InPath deployment, the InPath LAN and WAN interfaces functions as a bridge interface. I need some one who could help me understand this concept.
Refer the 'Figure: Logical In-Path Interface in a Single Subnet In-Path Deployment' section in the below URL that you could use to help me understand the concept.

Purpose: To help me thoroughly understand the concept of the connectivity done when river bed intercepts the traffic.

Purpose: To help me thoroughly understand the concept of the connectivity done when river bed intercepts the traffic.
In this deployment type, the Riverbed is acting as a "bump in the wire" that is not recognizable to the other devices in the network. This is similar to the Virtual Wire deployment on a Palo Alto. The key difference is that the Palo Alto is performing deep packet inspection at line speed and the Riverbed is optimizing outbound traffic in a similar fashion.

Hi Harold,
Thanks for your post.
Just wanted to confirm if there is some document that you could help me with that gives an in depth explanation of the concept.
