We have multiple cases of 3550 switches setup like this (pure L2):outside world - 3550 VTP server - 3550 VTP client - 3550 VTP clientwith VLAN trunks between the switches. If I am connected from theoutside to one of the 3550 VTP clients, and change V...

A 6509 handles BGP with full routing tables just fine. But note that Sup2/MSFC2/PFC2 can *not* handle full routing tables combined with uRPF (ip verify unicast reverse-path). A 6509 is also very good for handling DoS attacks, since packet filtering i...

The 6500 with MSFC2 and PFC2 can do routing just fine - it's a true router too.The real difference between 6500 and 7600 is marketing.(Before Sup720 came along, you could explain it simply as: 7600 equals 6500 with Sup2/MSFC2/PFC2 and at least one OS...
