Re: Client information?

For ISP, I don't care what applications customers are running. As long as they are legitimate, it's o.k. with me. Only concern will be whether they are running malicious code such as Virus, Spam, DDoS client, or not, which means abusing network resources and other people's resource. For that

Did you check with hotel whether they have available fiber or coax from local CO ? In that case, installation cost may be reduced since it is matter of cross-connection with local ISP. Hotel may have special arrangement with local ISP just in case of conference or something like that. Hyun

If I remember correctly from M5/M10, they uses FEB (built-into-Chassis FPC version), and each FEB (row) has restriction up to 3.6Gbps rate. So total aggregated bandwidth can not go over this limit. If you install 4GE (4 of 1-port GigE PIC) in same FEB row, you can use 0.9Gbps in average per

My question is whether the number resource including IP address is trading item or not. In my understanding, IP address is allocated from ARIN based on use right, not as an asset. If one network is acquired by somebody else, IP address is transfer to new guy based on network engineering

In reality, from what I see, most large ISP doesn't care about RFC1918. I've been dealing with this issue for a while. Not all of them, because I didn't deal with all of them. But some of them has strange policy for ACL, because it has large impact on router platform CPU utilization. Strictly

7600 platform, you can not change MTU size for MLPPP/MPLS because of bug CSCdj40945. That problem said it is fixed, but you still need to check your IOS whether it has a fix for this or not. Hyun Hyunseog Ryu wrote: Maybe next monday I can ask for detailed info, but I wasn't on the meeting

Overall, MLPPP may work fine with MPLS as long as you have single virtual circuit from each physical circuit. Such as T1 channel from Channelized DS3... But you have to use sub-interface (logical interface) other than sub-channel from channeliezed circuit, you may have some problem. If you

What I heard from Cisco is that there may be some issue with MLPPP and MPLS - maybe QoS? -. The issue is for general IOS support issue for MLPPP/MPLS combination. For that reason, Cisco recommended Multi-link Frame Relay(MLFR) to overcome that issue. Hyun Jon R. Kibler wrote: Greetings all,
