For those of you that have been brave enough to run IPv6 on your Cisco wireless infrastructure, I wanted to ask a question.
We are running into a peculiar situation. We have three WiSM2s (7.4.110), in three different locations, all running on individual Cisco 6500 Catalysts. All the SVIs in the L3 switches are configured with IPv4 and IPv6 addresses. The WiSM2s are all part of the same mobility group. When a client joins the wireless network, it gets a v4 address and then three v6 addresses. The v6 addresses correspond to the three different interfaces on each WiSM2. We suspected this had something to do with mobility. So we deleted the mobility members from all WiSM2s and clients got a single v6 address. But we have to have mobility. So, then we tried suppressing router advertisements on the SVIs, and that sort of worked. Clients now get a single v6 address from their parent controller, but interestingly enough, they eventually lose their v6 default gateway. The reason? We have no clue. Anyway, have you guys run into this really fun issue? Thanks and have a great weekend!
