Hello folks, I am looking at a strange issue and I was wondering how some of you have seen this done.. On a Metro E connected network with 5+ links and in some cases several fiber interconnect switches between the sites.
Typically, on a LAN every time a BPDU crosses a switch the MAX AGE time is reduced by 1 every time it crosses a switch. So that makes me ask, do Metro E switches do this? I suspect yes, unless some kind of QinQ parameter change in effect. Fiber management devices?IE fujikura, or ?? In this case the layer 2 spanning tree topology, if extended via Metro E, the Metro Layer 2 hops count towards the diameter of the spanning tree topology? How does QinQ tunneling impact this if at all? Thanks, Jim _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
