What are the major differences between 65XX and 76XX in terms of technical specification? Almost all their major line cards such as FE cards, FlexWan etc and even Sup engines are interchangable. Their backplanes and switching performance are also very similar.
NEBS stands for "Network Equipment-Building System"
NEBS describes the environment of a typical Regional Bell Operating Company (RBOC) Central Office (CO). This description includes spatial and environmental criteria. Typical equipment line-ups are described including the environment they're exposed to.
NEBS was developed by Bell Labs back in the 1970s to standardize equipment that would eventually be installed in a CO. The intent was to make it easier for a vendor to design equipment compatible with a typical RBOC CO. This would result in lower development costs and ease the equipment's introduction into the network.
The 7600 can run Hybrid code, beginning with version 6.1(1b) of CatOS for the 7609-DC, version 7.1(1) for the 7603, version 7.2(2) for the 7606, version 7.6(1) for the 7613 and version 8.1(1) for the 7509.

IntroductionOSPF, being a link-state protocol, allows for every router
in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
