MPLS question

vanguard1 · ‎10-31-2007

Hi all. We are in the midst of rolling out Mpls to 5 of our remote sites. 3 sites will have a cir of 10 mbps, 1 100mbps, and another 250 mbps. I am planning on running ospf in each site. My question is, will a 2821 router at each site be sufficient. Voice and data will be in use, so traffic shaping/qos will need to take place on these routers. Will this work. Thanks for your help.

Yes 2821 is sufficient to handle 10 mbps traffic.

For the 100 and 250 Mbps sites, you'll probably need to consider the 7200 series.

We have decided to go with 3750 Metro for the 100 and 250 mbps sites. Will be running ospf between sites. Any tips in terms of traffic shaping/qos?

Ah, you didn't mention you were using Metro Ethernet connections. 3750 will easily handle 100 or 250 Mbps.

As for tips for QoS, insure your voice is sent first. All data could be placed in a normal class or you could split it, with the 3 remaining classes, into critical, normal and scavenger if using non ES ports. Doubtful you need to do much more if using one of the ES ports, although it would be nice if you could do FQ in class default like you can on WAN routers but don't believe you can.
