Hi,
I have just purchased a mikrotil 1100 routerboard and want to get started, i have a couple of questions
1 What defines an edge router? The fact that it routes to multiple networks??
and
2 How do i go about setting up routes to different networks on the 1100?
Thank you
1:
My definition of an Edge router is one that connects to another providers network.
For example I may have 20 routers in my network. They will all have multiple routes so know where to get to different subnets in my network but I may only have one of them connected to AT&T. AT&T is a provider that I pay to get routes that are not on my network.

If you are small (3 routers) then you may want to just start out with static routes. You will soon grasp a good concept of routing and hopefully the understanding this does not scale well. 
When that happens you want to start looking at routing protocols like RIP, OSPF, BGP.

Thanks so much for that
ok so i then connect more than one router to each different port and manually set it up???
