[j-nsp] juniper router reccomendations

Hello James

What do you mean with turbo fib ?

Is a new config from 15.1 ?

Thanks a lot

That has some merit, as the OP was right in that for this job I don't really care about timbuktu more as whats 'close' to my two ip transit providers. I know nothing of juniper and I'm just wondering if MX80 is enough box for this or if I need to go higher up in the food chain. The one iptransit provider at my 'A' location appears to originate about 20 networks from various netblocks and this would be easy to statically enter into config while accepting defaults from both, achieving the same net result.
