Re: 100MB uplink to ISP [7:5026]
Hi Hans, Please note, 7206VXR has two PCI buses , each supports up to 600Mbps, slot0 ,1,3,5 connects to PCI mb1, slot2,4,6 connects to PCI mb2. You can look at for all PA required bus bandwidth point (kinda marking scheme), for atm is 300, for I/O with 1FE is 200, for FE-TX is 200. The max bandwidth point for each PCI bus is 600. Therefore, you can place two PA-A3 to mb2 (total bandwidth point = 600, max allowed bandwidth point), and then one PA-A3 to mb1. Since mb1 is included slot 0, in case it is NPE-300 the bandwidth point on mb1 will become 500. So, somthing like this: |5PA-A3 |6PA-A3 | |3|4PA-A3 | |1|2 | | 0NPE-300 | If you ever want to put another high-speed interface to either PA slot, you will have an error message of "max bandwidth exceed" on your console. You can, however, put an extra PA-FE to it and ignore the error message. BUT, I found if I do that, all the FE ports (PA, or NPE300) will have a serious level of interface reset. in whatever traffic rate. Suppose your ATMs are for incoming and outgoing traffic and not for "transit", then all the ATMs are pumping data toward the FE on NPE-300. So, you can imagine it is not an effective configuration. You may find this link useful: http://www.cisco.com/univercd/cc/td/doc/product/core/7206/port_adp/3471pac6. htm If I were you, I will not go for 7206vxr since the initial config is already hitting the max. Neither 7507. if you don't mind, I will recommend a Juniper M5 with 2 dual ATM pics and 1 Quad FE pic. and you still have one pic slot for expansion. I am not associated with Juniper Networks in any way it is just my thought about Cisco 7206vxr series.

See http://www.cisco.com/univercd/cc/td/doc/product/core/7206/port_adp/3471pac6.htm, theres a chart near the bottom talking about a point bw system.

Re: 100MB uplink to ISP [7:5026]
What are the facilities the Telco is providing ??? 100 Mbps can be carved from an OC3/ATM & SM/Sonet Interface. A large piece of the puzzle, should be in what's deliverable. The 7206 VXR should handle this fine. You would NOT want to join all these connection on same router though, it would take out all your redundancy out. One setup we had, used dual Catalyst 3524's (Distribution traffic) running Fast Ethernet into matching dual 7206 VXR's. The VXR's each had OC3 connections & HSRP running, allowing us to continue with the redundancy paid for on the Telco & ISP side.

100MB uplink to ISP [7:5026]
Hello group, I have a customer who wants to know which Cisco router (and appropriate port adapters) he needs to provide three 100MB uplinks to three different ISP4s. According to my own research, the 7206VXR with three OC-3 SONET-STM1 cards should do the job. Do you think this is the best solution ? I am not sure if the 7206 can handle that much bandwidth. Thanks for your input in advance. Regards, Hans _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
