The 7200 architecture dates from the late 1990s, and is basically modeled on a PCI-bus UNIX workstation from that era. The 7200 is usable today as a WAN aggregation router for T1 access, and nothing else. Using it as a GiGE transit router will place a non-deterministic node in the network, unable

While I agree it may not be suitable for transit GigE purposes, it is certainly acceptable for many WAN aggregation scenarios and CPE scenarios well in excess of T1 speeds. There are still many out there in DS3, Fast-E, subrate ethernet subscriber, ATM, (DSL/L2TP/PPPOE), DMVPN, and other similar

Hi all, I have a 7200 series router (7204) here and I am trying to figure out something with it. Currently the router has a NPE-G1 card in it, giving it 3 gig interfaces but I need an extra gig interface on it to make 4. Having a look around the available options are either get a PA-GE card

Hi, The other option left is the I/O controller. I found that you can get a port adaptor jacket card [2] for the 7200's that let you stick a normal interface card into the I/O controller slot (instead of the I/O controller itself). My main concern is if the jacket card uses its own PCI
