What do the SFP-GE optics give me that the GLCs don't? The SFP-GE-* ones are newer, and support DOM. It makes no sense that two different parts exist and customers are forced to keep spares from each. GLCs should have disappeared long time ago. Yes, DOM doesn't work on 6748 cards yet. It's a

Hi all, A memory loss problem here. We/ISP_A are trying to leak prefixes (which are not seen on the public Internet) to a remote network/ISP_B via BGP. At this point of time we are planning to build this via BGP over a IPv4 tunnel interface. ISP_A---Transit_Provider---ISP_B

Hi Guys, is it a good idea to use the virtual mac adress feature in a failover configuration ? How is you experience with that ? I have PIX515E cluster with PIXos 7.2(2) . If I want to use that, should I always use the same virtuall mac addresses on all interfaces, or should every interface have

Thanks there's a lot of other servers in the same subnet (layer2 adjacent as well) and they must be able to talk that confirms what I thought I was understanding from the docs... We can of course do this server level...;) My last question would then be if we ran NAT with SLB then the

Paul, I recommend that you look at the ACE module. It's the latest and greatest HW based SLB solution (a blade on the 6500): http://www.cisco.com/en/US/products/ps6906/index.html If you really need to be able to provide access to the VIP from the same L2 domain where the real servers are

I tend to use tick and tock (.usno.navy.mil) for my stratum-2 servers. There are others which allow public access, but why not just go to the horse's mouth? The horse can pretty far away. If you're topologically distant, then access to tick and tock might have substantial amounts of
