Yep. I'd do either some sort of combination of multihop bgp or VLANs to the customers needing bgp routing. VLANs really are quite simple at least on procurve switches and mikrotiks and junipers. VLANs reduce broadcast traffic on bridged networks so long as the vlans don't extend to places they are not needed. We have every sited routed with mikrotiks using private ASNs and BGP, but we also have procurve switches on most sites' backhauls, so we do extend a vlan across multiple sites if we want for a particular purpose, and everything else at the sites is routed. We have stayed away from using switches for L3 because of routing limitations and for CALEA; I think it's easier to capture traffic on a router than off a switch port, because if your switch has traffic duplication you'd still need a router to route the traffic back to the collection point. > For Core Router in the Cisco world you are looking at something with a > G1 or G2 engine ...

M10i or an M20 (if you like redundancy...) cost on > the secondary markets about $8 to $10k We're using a Juniper J2350 with upgraded non-juniper RAM for 2 full BGP and presently 150+mbps of Internet. Comes with 4 1gbps ethernet ports. It was in the $2500 range iirc. There are switching features in it, but I haven't tried them. I bought it to do BGP. We can do a real nice MT for 1/3 that, but Mikrotik's BGP is not as well documented as Cisco/Juniper and we were willing to pay for software that was a little more mature/tested. We use MT BGP internally all the time, but that's a much smaller BGP network than the Internet of course. The j2350 will probably go to 300mbps perfectly fine and we'll upgrade again. There are a couple J series models that go higher performance than this and will be a lot cheaper than a M series chassis router. If you want up to date software and initial tech support, buying new is the way to go unfortunately. Unlike Cisco, you do get a reasonable period of tech support and software updates without buying a separate service contract. The BGP on this has been flawless. Juniper has a tool on their site to convert cisco configs to configs for their OS which was quite accurate. We upgraded from a Cisco 7507/rsp4 router which was running out of ram and steam and sucking too much power. > You could use a Mikrotik Power Router.. cost $ 2500 to $5000 > > Only the Cisco 7301 and Mikrotik are small and consume little power... > Everything else is big and consumes power. > > Most common, cost efficient network design would be to use GigE Switches > in a ring or your favorite network topology, with one or two Routers > located at DataCenters or NOC... > > > If you find some other solution, that can do what you are looking for, > please share it with us, cause we have been looking too... what I am > sharing above with you is what we have found so far. > > Regards. > > Faisal Imtiaz > Snappy Internet & Telecom > > > On 9/8/2010 7:16 PM, Jon Auer wrote: > > Needing full BGP routes takes you out of the realm of cheap Layer 3 > > switches... > > You need to worry about TCAM (hardware route memory) in addition to > > RAM on Layer 3 switches and apart from decked out Cisco 6500s or > > greater you aren't going to find that. > > > > The Juniper MX80 should work.
