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 s

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 t
