[j-nsp] Core network design for an ISP

[Matthew Crocker]

Hello,

What is the current best practice for carrying full tables in MX series routers?   I have 3 new MX480s coming soon and will use them to rebuild my core network (currently a mix of MX240 & MX80 routers).  MPC-NG (w/ 20x1g & 10x10g MICS )& RE-S-X6-64G-BB.

I’m running MPLS now and have full tables in the default route instance.   Does it make more sense (i.e. more secure core) to run full tables in a separate virtual-router?  I’ve been doing this small ISP thing for 20+ years, Cisco before, Juniper now, I’ve always bashed my way through.

Looking for a book, NANOG presentation or guide on what is current best practice with state of the art gear.

MPLS?  BGP? IS-IS? LDP? etc.

The network is a triangle  (A -> B -> C -> A),  MX480 at each POP,  10g connections between POPs,  10g connections to IX & upstreams.  Most customers are fed redundantly from A & B

Thanks
