Re: Failover how much complexity will it add?

So if my requirements are as follows:

- BGP router capable of holding full Internet routing table.  (whether I go for partial or full, I think I want 
something with full capability).

- Capable of pushing 100meg plus of mixed traffic.

What are my options?  I want to exclude openbsd, or linux with quagga.  Probably looking at Cisco or Juniper products, 
but interested
in any other alternatives people suggest.  I realise this is quite a broad question, but hoping this will provide a 
starting point.  Oh and
if I have missed any specs I should have included above, please let me know.

Thanks

Adel

I think partial routes makes perfect sense, makes sense that traffic

thinking of BGP router choices, sure I have a plethora of choices :-(


Personally I'll always go for full routes if the router has enough
memory (software based) or TCAM space (hardware based). Cheaper to do on
software platforms though. An entry level Cisco 2811 can take full
tables from multiple upstreams with 786MB RAM or even 512. It won't push
100 meg of mixed traffic though.
