Hi, I've only really dealt with traffic levels under 20Gbps. I have a client that will be pushing over 100gps, and close to 200 within the next six months, at least thats the goal. Judging by the type of traffic it is...I could see it happening. I'm probably in over my head, but thats another topic.
The plan is to run OSPF from a couple existing MX480s I setup to a new switching core which is running VRRP and extending L2 out to existing end of row switches. This leaves me with hoping that OSPF ECMP works well enough to push these kinds of traffic levels over a bunch of 10GE links, load balancing between the upstream MX routers. Can I rely on ECMP for this type of setup? Each MX will have about 50Gbps provider connectivity to start, and will have ~150Gbps by the time the contracts ramp up. The MX's are not at the same site, so I'm limited to using 10g links site to site over their cwdm. This leaves me then with a problem; getting a bunch of capacity in L2 form to the EOR switches. At least on the EX4500 (we will move to bigger), the max number of links for a lag is 8, so 80Gbps. And I can't expect to really make complete use of that. Do people use MSTP for this purpose at all? Spreading environments over a couple 80GB, or a few 40GB lags? I could also run 40GE ports in lag...but will juniper devices allow LAGs with 40GE ports? Also...any tips on handling all of the provider connections? I don't know if they will be giving us lags, which means I'll be potentially running 10-15 BGP sessions per MX, which is a lot of routes. They're running the RE-S-1800 quad core 16GB, but should I opt for partial or just default at that point? Its possible all of the links will be from the same provider. -- Thanks, Morgan _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
