Ah - MPLS.Yes there are several large carriers with MPLS
deployed or in the process of deploying it (equant, global

such as ATM (AT&T for example). Others backed away from it but

Hi All,
I got a problem in the production campus LAN here between VLANs. Please
help me out! Below is the scenario:
We have VLAN 10 (10.10.x.x) and VLAN 20 (10.20.x.x) subnets. Routing is
enable/allowed between the two subnets using MSFC of the 6500. Each subnet
has a DHCP server to assign IP
I'm trying to figure out if this truly interesting discussion is disguised
as a flame

you'll need a WIC with a async/syn serial port, I know they're available for
the 1700's, but I'm not sure if the same wic will work in a 1600. then you
can specify the interface as async and connect up the modem with a
db60-rs232 cable.
