I know this is an old thread, but I found one workaround yesterday. Had exactly the same problem with two 4500-X switches. One switch would advertise summary static route pointing to Null0 as external and another one advertised it as internal route. Exactly the same behavior OP has posted. Both switches had identical IOS version and configuration (explicitly redistributing static route in eigrp configuration). After several hours of reading same configuration lines over and over and resetting EIGRP neighbor sessions many times, I noticed one difference. Previously the switch, which was advertising static as internal, had network statment 0.0.0.0 configured (which would also include static to null0) and then it was removed from configuration. Other switch never had matching network statment for given summary network. This led me to thinking, that network statement gets stuck somewhere in memory in IOS, and although it is removed from configuration and does not match the networks exclusively, the effect for directly connected static networks remains the same. So I've deleted whole EIGRP process, reconfigured it and the redistribution started working correctly!

Thank you for the reply. Connectivity problems are ruled out, simultaneous CLI connection is up and well. I also think this has to do with HTTPS session timing out. Is there any configurable keepalive service in ASA OS for ASDM sessions? ... View more

Hello Jonathan. Thank you for the reply. I've checked both those resources, but they're describing AP side configuration (which I've already done). What I'm trying to find is an example of RADIUS server configuration itself. What RADIUS attributes do I have to use on my server, to successfully authenticate users who try to connect to SSID? ...

Transparent switch does not synchronize its vlan database with VTP servers, but it passes incoming VTP updates to other trunked switches. So if you have  swA(VTP server) <-> swB <VTP transp) <-> swC <VTP server/client> Switches A and C should be able to update and sync their vlan databases. But for that to work, I believe VTP domain name should match with both, transparent and non-transparent switches across VTP domain. ... View more

Thank you Ruchir for the detailed explanation and an informative config example! One quick question: So for L3 termination when QinQ is used, under service instance you would need to use " rewrite ingress tag pop 2 symmetric" poppoing 2 tags right? ... View more

Yes, the summary route overlaps with specific route, but why should it suppress more specific route, given that the route is with the longest prefix possible /32. Changing summary route is not an option, not possible. ... View more
