  • 1.  RAPs ignoring LMS IPS in cluster

    Posted Sep 26, 2018 08:22 PM

    I have a new Aruba 8.3 cluster setup and I am finding that the Remote APs are ignoring the LMS settings.

     

    First of all, I am not using NAT. My two controllers have real external IPs and private internal IPs.

     

    Even though I put LMS entries for the RAP AP-group and ap-system-profile, once the RAP builds it's initial VPN to the Master controller external IP, it then tries to build tunnels to the two controller internal IPs. These fail, of course, since the RAP has no route for these, and the RAP ends up with just one tunnel to the Master controller IP.

     

    If I set the rap up inside the network, the process is the same, it starts by building a tunnel to the external IP, then builds two tunnels on the internal IPs.

     

    Can anyone explain how to the RAPs to build two tunnels to the External IPs without having the change the "switch" ip to the external IP? If I did that, I suspect all of the internal campus APs would stop working.

     

    BTW, I already have a ticket open with HPE support, but they have been just going around in circles and seem fixated on the lc-rap-pool not being an l2tp pool

    Please see here:  https://community.arubanetworks.com/t5/Wireless-Access/controller-clustering-with-remote-ap-s/m-p/418925#M80254

     

    "As mentioned above, it's a known/stated limitation with AOS8.x. This is due to how controller information is signaled to APs when clustering is enabled, via the nodelist, which takes priority over the previous controller discovery options.

     

    The previous methods of RAP redundancy using LMS and Backup LMS IPs in combination with VRRP are still options, but due require that the controller not be a part of a cluster. "
