The EoGRE feature on Cisco WLC's is new to me but looks like it is a good solution for some problems. However, I'm having a bit of trouble understanding the terminology and how it all works. I'm a bit puzzled about the functions of realms and domains. As far as I understand so far I created a new interface on my WLC and used that as the source of my tunnel. I then attach that tunnel to my SSID. When the traffic gets to the other end, if I tunnel several SSID's, what differentiates the traffic at the tunnel endpoint such that it gets attached to the correct tunnel and subnet? When I look at an example tunnel endpoint config in the following url
I’ve worked out that the differentiator is a vlan that you can apply to a eogre profile. Once the traffic gets to the tunnel endpoint you can apply a vlan to each tunnel and the matching vlan determines the tunnel the SSID joins. The interface/vlan the SSID is attached to on the WLC becomes irrelevant. It is the vlan in the profile that’s important. One other thing though, I can’t understand the use of realms in the profile. Anyone used this feature?
