My 2c's worth inline: > - M5, M10, M20, or M7i - what is my best bet for the traffic > levels mentioned above? We need the basics - BGP, OSPF, GRE > tunnel capability, and some basic ACLs. Nothing fancy like MPLS, etc.
All of the above are capable of handling the traffic levels mentioned without any issues. GRE Tunneling will require a tunnel PIC or an M7i with an integrated AS-PIC, unfortunately. > - What is the difference between the non-"i" series vs the > newer "i"-series? e.g. M10 vs M10i. How about the "Enhanced" > vs non-Enhanced chassis? The M7i/M10i are a newer chipset, which is required to support some of the newest PICs (e.g. 4 port Gig-E IQ2). They're also smaller and lighter - the original M5 and M10s could have eaten more salad during the design process. The M10i also has redundant routing and forwarding blades, which its predecessor didn't. http://juniper.cluepon.net/index.php/M10i may help you out. > - What M-series router should I be looking for on the used > market? Specifically, what one should have the greatest availability. I would imagine used M5s and M10s are going to be most available. Make sure they are the version with the E-FEB, which supports newer cards like the SFP-based Ethernet PICs. Ideally for future-proofing and most cost-effective support of GRE, get the M7i with integrated AS-PIC. Watch that M20 and M5/M7i/M10/M10i PICs are not (practically) interchangable. > - What routing engine should I be looking for?
