I want to design cisco network to connect 30-35 sites with leased line as primary and ISDN as back up connectivity. suggest me the router with modules at central site and remote site also firewall, IDS,switch ,NMS, routing protocol . suggest me the network design can I use Mux in central site.

Call cisco and they will give you efficient advice on all of your hardware. And if you can help it, lose the ISDN.

Contact Cisco. They have divisions that do nothing but help companies set up their networks.

They will analyse, design, configure and even program the systems.

As another has said loose the isdn and go dsl for backup. This can be run into the Cisco equipment for auto backup.

Good Luck Lee

If you are going to be the administrator of the network, I would suggest taking Cisco's networking classes. Contact your local Technical college, or collage for details. You will greatly benefit from this.

Use the CCO consultants tool to select the hardware, but your question is somewhat obscure. You say you have "a" leased line to connect 30-35 sites. If it is a Point to Point DS1, then you can only connect one site. If it is just a standard DS-1 for ISP connectivity, then you will need some sort of secure tunneling to connect all of the sites. GRE will suffice,and and works fine on both Cisco routers and Cisco PIX firewalls. DES3 is better. A 2621 with a WIC 1 DSU is sufficient for a single T1.

The real issue here of course is the failover. And there are several ways to accomplish this. The best of course is a routing protocol, and while there are different preferences in this area, I prefer and recommend OSPF. OSPF is vendor neutral,and due to it's link state is quite fast and able to reroute your traffic quickly.

Some prefer EIGRP or BGP. EIGRP will make the switch a little quicker, but it is Cisco proprietary, and in my judgement, does not handle subnet masks as well and precise as OSPF, as OSPF offers more precise definition of network subnet addresses. BGP will get you into trouble with your ISP if you don't know what you are new to routing, which from your question is assumed.

In some instances a higher metric static route or prefered gateway will work, but I would go with OSPF for 30-35 sites.

Hope this helps

ISDN could be OK for backup, dependent on bandwidth requirements try using T1 or E1 PRI for hish speed. A word of caution on using DSL for backup. It is difficult to incorporate a dynamic routing protocol (e.g. OSPF) into such configurations, thus making it much more difficult to ensure that backup will be established automatically in the event of all connetivity problems (DSL would be a multi-hop Layer-3 connection over which you don't have control of all the routers) - ISDN provides a Layer-2 path directly between routers under your control.

Hi,

You have mentioned that you wanted a Cisco Network with Leased Lines, but you did not mention what r the services you are planning (Data, Voice, Video) also the bandwidth of the leased lines (E1, T1, 64Kbps, etc.)

You can as well use a MUX at central site but it is always better to go for end-to-end cisco Network.

If you can give me more idea on the above points, I can generate the complete BoM and send you.

Mail me back if you need my help.

ALL THE BEST.

Bye
