I have now been using the 871W router for several months. I picked one up to do lab work for IPv6, routing and the VMware hands on class I have been doing for Pacific IT Professionals.
I am VERY impressed with these routers. I can run EIGRP, RIPv2, OSPF, BGP, IPv6, OSPFv3, 6to4, DMVPN, CBAC and wireless all on one device. I am amazed at the diversity of what the product can do and how quiet it is since it has no internal fan. I think it really is the perfect remote home office router. If they made it POE by default it would be a perfect product, IMHO.
Just wanted to give my thumbs up for this great router!
