> 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.

Remote MICE members?
by Steve Howard Sept. 21, 2011

Sept. 21, 2011

Hello, CNS has received a request from one of its customers for a direct connection to MICE. If the consensus is to move forward, we could haul the MICE VLAN to that customer (and presumably to any other CNS member or customer who wants a direct MICE connection). This could result in the MICE VLAN appearing at various places throughout the region. I think that this could be a good thing for MICE, but if not managed correctly, it has the potential to be troublesome for problem isolation. MICE already has remote switches at 511. Other exchanges often have switches connected throughout their city. In this case, it is a little of both – except that the individual remote connections could be farther away in different directions. Does that matter? Whether we add remote connections or not, I'd like to see us come up with a plan for spanning tree. It probably would be best to make sure that our spanning tree root is one of the MICE 10Gig switches (probably the main one?). Or, alternatively, we could disable/filter spanning tree altogether and do MAC filtering for loop prevention. I think that spanning tree has its limitations, but it is much easier to maintain then MAC filtering. It looks like the current spanning tree root is 00:0c:db:fe:af:00 which looks like a Brocade device. Hmmm... We might want to change that... What does everybody think? Are there better ways to do this? Thanks, Steve ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

SDN 10G Mice Upgrade
by Jay Hanke Sept. 9, 2011

Sept. 9, 2011

Mitch, We're starting to run low on 10 G ports on the main stack. Is SDN still planning to upgrade? Also note, you're likely going to see a large spike in traffic when Akamai goes live on the exchange.

Mice routes via Northern Lights GigaPoP
by Jeremy Lumby Sept. 6, 2011

Sept. 6, 2011

I have a case where I am seeing 199.199.0.0/16 in BGP via MICE/Northern Lights GigaPoP. I have noticed that traffic to this network takes MICE, however the return traffic is coming in across one of my public Internet connections. I am assuming that either by choice, or by accident that they are not accepting my route via MICE/Northern Lights GigaPoP. I am wondering who would be the best person to chat with about this since MICE does not list a peering contact for Northern Lights GigaPoP in the participants page, and I realize that the correct peering contact might be another level or two deeper.
