In this post we will learn about how to configure the foreign mapping between 2 controllers.
Auto-Anchor mobility, also known as Foreign Mapping, allows us to configure users that are on different foreign controllers from different physical location to obtain IP addresses from a subnet or group of subnets based on their physical location.
- First of all Both controller must have added each other in its mobility list.
- Auto anchoring must have conifgured.
How to Configure Auto Anchoring
Steps to conifgure Foreign Maping on Anchor ControllerL
***Make sure that it is only configured on Anchor Controller or where we want to terminate the client to get IP address.
Step1: Select the WLANs tab.
Step2: Click the Blue drop down arrow for the WLAN(iN my case RSCCIEW) and choose Foreign-Maps.
Step3: The foreign mappings page appears. This page also lists the MAC addresses of the foreign controllers that are in the mobility group and interfaces which are created on Anchor WLC.
Step4: Select the desired foreign controller MAC(WLC2 in my case) and the interface(rscciew) to which it must be mapped and click on Add Mapping.
