I'm looking for some advise on a C or J router. Requirements: 200 mbps of throughput (small packets) 4 GigE interfaces (copper or SFP) ip verify unicast reverse-path support in hardware. BGP4 with a decent CPU to handle full tables. My plan is to peer BGP with my border routers and pull in full

[c-nsp] SFP compatibility with Cisco switches

Howdie, I'm think about using some RAD SFP for T1 & T3 service. The SFPs support I2C communication with the host. Does anyone know if Cisco switches support I2C communication? Would these SFPs work in Cisco gear or will I have to go with a different switch vendor? A NEBS Compliant S

Re: [c-nsp] Typical broadband aggregation rates

It depends on the type of customer, for residential DSL I tend to count them in a 100:1 over subscription bucket. Business DSL is 10:1 but their usage patterns are different. I sell bandwidth to some local colleges and they are 1:1, they buy 30mbps, they use 99% of that 80% of the time

Doesn't the 10k use Ciscos FPGA chips (aka PXF)? So if a feature isn't in the FPGA code it gets punted to the main CPU and performance goes to hell? Isn't Cisco doing away with all the routers based off the FPGA code? NSE-100, 7301, NSE-1 *very* fast when the packets can be handled in

Nathan, It sounds like what you want to do should be possible. I'm not sure if the 7206 can do it or not. I'm pretty sure a Redback SE-400 can do it. You need to unwrap the layers of the onion... Build a Bridge group on the 7206 and attach each PVC to it. That should create one

Re: [c-nsp] preventing unwanted devices on the network

802.1x provides Ethernet (layer 2) access control. You enable it on your switch ports and all Ethernet devices need to authenticate. Using Radius you can assign authenticated users to various VLANs etc. Your devices need to support 802.1x in order to authenticate but most modern OSes

[c-nsp] MPLS capabilities of SUP2

I'm working with a customer on a network redesign. The plan is to use 7206/NPE-G1s as PE routers and 6509/SUP2 as P routers. The SUP2s would only need to switch the MPLS tags they won't need to do anything special. The 7206s will handle the grunt work of maintaining per VRF routing ta

I'm looking for a router with 3 GigE interfaces, capable of moving 1gbps of traffic (64byte) and a full BGP table, with room to grow. This would be for a border router scenario, 1 GigE from my upstream, 1 GigE to my core switch and 1 GigE to interconnect two of these routers. Right no

Re: [c-nsp] VOIP QOS

AutoQoS doesn't perform any voodoo to the config and the results are pretty well documented in the IOS docs. Basically it sets the switch ports to trust the DSCP or CoS values and then builds the appropriate DSCP to queue table. Your VoIP packets need to be marked with the proper DSCP v

Justin, What you want is Ethernet in the First Mile (EFM). I have a Zhone MALC 723 in my lab running bonded EFM over DS-1 to their TNE-1520 CPE. Works like a charm. I can map DS-1s into VLANs or run dot1q trunks over them. The 723 can also do some basic IP routing, I *really* wish
