Hello All,

There's a task taking place shortly and I'm trying to grasp a hold of the situation.  Due the the remotness of one of our backoffices, the only connections our provider can give to use is 2mbps frame relay connections.  We are having 4 of these installed.

The challenge is this, how do we effectively connect all of these links to a 'cisco' router(s) in order to get them to participate as a single connection or thereabouts.  We have asked the provider if they can provide a switch-to-switch option but this is apparently not available so it must terminate at a router.

What I need to know is this:

a)  What cisco router and wan cards would suite the job of handling at least 4 (but up to 8) 2mbps frame relay links (I believe the interface connections are X.21), preferably with dual power if available and also to support 2x fast ethernet and 1 x PA-4T+

b)  Each line has it's own IP addressing and is considered an independant link at our provider, the provider said they would provide ASN numbers.  What method would be used to effectively make use of all connections similar to a single connection


Any other information or suggestions would be most appreciated.
Thanks
Anubis.

Hi

a) If you get something like a 2811 which has 4 WIC slots and still has room for a network module it should do what you need. You can get high-density nework modules that have 2 X.21 interfaces per slot. The 2811 doesn't come with a reduntat power supply, but you can buy one (and RPS-675 I think) that supplies DC power in if that is a must.

b) If you run a routing protocol over the link that supports load sharing such as OSPF all of the links will be utilised.

I hope this helps

Hello LANWorx,

Thanks for the reply.  I have not heard of OSPF before.  Do you know where I could look this up further?  Is this available in IOS?

Thanks
Anubis.

OSPF is a routing protocol (sorry I wasnt clear). It is very common and is found on the IOS. OSPF will learn routes and put the in the routing table, but it puts an entry in the routing table from everywhere it is learnt from and the IOS will use each of them to load balance.

Here is an article that explains it and how to configure it: http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_configuration_guide_chapter09186a00800b3f2b.html

Cheers :-)
