I would like to get some feedback from other Engineers that have worked with Cisco's 120XX series router, and the Juniper MXX. We are doing extensive testing on both platforms, and would like to get a feel for what other networks may be doing with either box. Any interoperability issues between the two? Are you using the Cisco or Juniper on the core/edge? Peering router? Any positive or negative feedback on either box is appreciated (replying privately rather than to the group is preferred). Thanks for the feedback! Scott Patterson Sr. Peering Engineer NetRail, Inc. Main: 888-638-7245 NOC: 800-621-1822 Mobile: 678-361-3208 Fax: 404-522-1939
