Hi,
I am looking aat desgning a Guest Wireless Network using Dual Anchor and Dual Foreign (Internal) WLC's for Redundancy.
For scalability I want to assign a single Guest SSID to multiple vlan interfaces on the Guest Controller using Interface Groups and Vlan Select.
Is this feature supported with 2 Anchor WLC's. Reading from below it seems that it is not possible if the WLAN is Anchored to 2 Anchor WLC's?
"As part of the VLAN Pooling feature, the “Mobility Announce” message will carry an additional vendor payload containing the list of VLAN interfaces mapped to a WLAN. This helps the anchor controller to decide on Local > Local type of handoff. The introduction of this feature also ensures that the inter release mobility is not affected. In a guest tunneling scenario, clients joining on “export foreign” will receive an IP address from the interface group mapped to the WLAN on the “export anchor” or as per the foreign mappings configured on the “export anchor”. If the clients who have joined over “export foreign” move to the “export anchor” controller, they may lose their IP address, which means mobility is not supported between those two. However, if the clients move between two “export foreign” controllers, they will retain their IP address, which means roaming is supported in that scenario."
