Hi All,
We supply quite a lot on 'LAN' connect services. These have a Gig coming back to a
core with a number of 100Meg ports some to various clients 'a shared connection'
others going to a site operated by the one orgaisation.
These come bace into a core and do so in the couple of major cores we provide this
network. The cores are connected using several ATM links thus providing a number of
VLAN's statewide. In a number of cases the 'backbone' ie the links between sites
provides less of a bottleneck than the LAN's they connect. This will however change
as the LAN's are upgraded.
Typically we would have something like a 2928G. This might provide several VLAN's
including 'public' and 'private' address space. These would be connected using 'BVI'
interfaces thus allowing integrated bridging and routable networks.
This works well and is being extended to others faster than I could imagine.
My to bob's worth,
