Cisco 3825 WAN capabilities

Unanswered Question

All,  I was wondering since I just found out that my Cisco 3825 router cannot support two DS3 WAN cards at full speed at the same time, is there a document somewhere or a web URL that gives direction in this area?  I am wanting to add another WAN 50Mbps Ethernet through another ISP and plan on using the second 10/100/1000 Ethernet port on the router, can the router handle this with BGP between the two ISPs?


Regards,

Also regarding running bgp on this you need to make sure that you have enough memory to handle the routes provided by your service provider.


if you have enough memory to handle the same then you dont need to worry about the same.


are you going to take the full internet routes from your sp?

I'm not sure on the BGP.  What are my options?

Does choosing an option reduce our internet capabilities?  What are the purposes of the BGP

options and the expectations of the choices?


Thanks for your response, this is our first time looking into using BGP because we are going to be having two separate ISPs.

Hi Patrick


Untill unless if you are not a small time service provider i dont see any merit in getting full routes from the ISP.

Instead you can ask them to advertise default routes which you can make use to navigate onto the outside world.

Your internal requirements should drive you to priortize or decide upon getting the full route or not.


Getting full routes regardless of the requirements / considerations is also a case, infact as a custom in few places where i have seen myself.
