If you are looking for an all-in one thing you are almost going to have
to go with a chassis from Cisco or Juniper or someone. I am a big fan of
the 3 tier design though. The BGP routers should just be doing edge
routing. The access and distribution layers should at least be logically
separate. Surte its more overhead, but it accomplishes a few things.
1.A goof in configuration at one layer does not take down the whole
network.
2.Upgrades are easier and usually cheaper in the long run. You are
replacing a device(s) which have a semi-dedicated function. You don¹t have
to have a device that has the horsepower to do 20 things. Instead it is
doing, say, 10 things.
If you are in need of full BGP routes your traffic must be increasing to
the point a shift in thinking is needed. Reliability should be #1 and cost
(to a degree) should be secondary.
