Frankly, I'm surprised at the outpouring of love for spanning-tree
I don't know anyone that loves spanning-tree, most people have more of an abusive older-brother sort of relationship. I'd lean toward STP being a necessary evil in a L2 environment where physical control isn't absolute for all the reasons David mentioned. I also like a bunch of the things Andrew brought up, but don't have a good feel for what the administration would feel like. It seems like I've spent the last 20 years either being disappointed in the performance of simple designs or being disappointed by the unpredictability of complicated designs... Anyway, this morning I've changed the main Juniper switch bridge priority and it appears to have asserted itself as the root. Steve/Jay/Doug - can you guys confirm that things look correct on your switches, I'll send you the Juniper's current settings off-list. Beyond that we can evolve in the direction the group thinks is best.

The cisco 4506 was setup for portfast/bpdufilter, switching it around would take the one remaining link on it down for a short period. So right now it thinks it is root because there are no other BPDUs allowed into it.. AFAIK, it is going away as soon as SDN switches over/upgrades their link? Probably not worth the disruption at this point in time. -- Doug McIntyre <merlyn@iphouse.net> -- ipHouse/Goldengate/Bitstream/ProNS -- Network Engineer/Provisioning/Jack of all Trades ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1
