The branch office models (100, 210, 240, 650) are all software-based forwarding engines, so nay. The 650 is pretty gutsy, but it's no EX. Word on the street is that there will be a model arriving soon that fits between the 650 and the 3400, but will be based on the high-end hardware (SPC/NPC) platform. > - Anyone ever tried to use one as an edge router w/a full BGP feed? Yes. Results were mixed, but generally avoid this scenario if you can. As discussed in other recent threads - flow-mode processing is not ideal for an edge-router (you move from a PPS limitation with a normal router to a session table limitation for starters), and performance-wise full-table updates are nothing to write home about.. though you will have plenty of time to write home about them while waiting for them to complete if you so wish.. > - MPLS -- mainly EoMPLS type stuff, esp. at the access layer This IMHO is where the SRX really shines and the "One-OS" mantra really sees the light of day. Juniper didn't leave too much out of the SRX code - EoMPLS, VPLS, L3VPN, Logical-Tunnel interfaces, it's all there - they really are the swiss-army knife of access boxes, and at a very surprising price. Just make sure you go high-memory for everything day one. SRX240s will take 2GB of 3rd party RAM quite happily too. > - Stability (we understand that this is highly specific to the JunOS release) You've got that right ; ) Seriously though, the MPLS-code in the SRXs seems to be pretty tight - most of the bugs I come across seem to be related to the security-processing and clustering side of things which is all (relatively) new. That said, since moving the majority of my customers to 10.0r3 my open JTAC Cases have significantly decreased (the same can be said for EX). That's not to say there aren't still some doozies out there though (turn on HTTPS in 10.0r3 and browse to the web interface, now make some coffee, now learn a foreign language, now log in). _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
