I had read that on our original deployment, and it's a nightmare to keep the documenation and configuration in synch. My personal opinion is that potentially failing 16 VSIs over to the standby at once (because they're all in the same group) - instead of just the affected ones - is poor policy. I agree, 6500s or 4500s for distribution are where it's at ... Unfortunately they cost a lot. Which is why the suits are considering financing them by charging for the features they provide. This has been a hot topic around the office, with all of us network guys saying `keep hsrp everywhere` because it makes our phones ring less, but we realize that network upgrades aren't free, which is making the non-IT folks all antsy. Regards, Randal

For example, a 3550 can do 16 HSRPgroups, limitingthe number of customers that we can attach to (2x 3550s) to16. That'sa lot of distribution infrastructure for 16 customers. Thento scalethat, say, to 200+ customers, that means we have 12-13 pairs of distribution 200+ routers, each with 2x gigE uplinks to the core ... Which means thateither (A) thecore has to be really big or (b) we get fewer, more powerful distribution devices. This is where my employer is at now - I admit, we're tiny in the datacenter world - but the cost to aggregate 100+ HSRPgroups into thecore, with room to grow, is pretty staggering for a smb. This why the suits are wondering if there is a revenue opportunity hiding somewhere to finance such a thing. Ah, the joys ofgrowing outof your britches :) Thanks for any continued response, Randal-----Original Message----- From: owner-nanog () merit edu[mailto:owner-nanog () merit edu] On BehalfOf Mike Lyon Sent: Friday, May 11, 2007 12:40 PM To: Randal Kohutek Cc: nanog () merit edu Subject: Re: HSRP availability in datacenters? So is the question: you are selling transit to your customers and you are wondering if you should charge your customer for allowing them to use your HSRP gateway instead of a physical interface on your router? Personally, if I saw a provider charging for thatservice, I wouldshy away from them. Only because it tells me they arepiece-mealingtheir services and are cheap. I would think a good provider would include that (and/or not sell it WITHOUT HSRP) in their sales offering. If for the only reason of customer support nightmares. If you have your customers on HSRPand you havea router go down, you wont have them calling you everyfive minutesbitching at you... -Mike On 5/11/07, Randal Kohutek <nanog () data102 com> wrote:My cohorts in suits have begun wondering if HSRP isstandard forcustomer gateways, and from there wondering if it issomething we should charge for.I did some research and came up with mixed results; I'dlike to hearnanogers experiences with this: In your experience, do datacenters provide free HSRPgateways, or dothey make you pay for it? Real world examples are better than Google :) Thanks, Randal
