Configuring VP Tunnels
This section describes configuring virtual path (VP) tunnels, which provide the ability to interconnect
ATM switch routers across public networks using PVPs. You can configure a VP tunnel to carry a single
service category, or you can configure a VP tunnel to carry multiple service categories, including merged
VCs.
Figure 7-12 shows a public UNI interface over a DS3 connection between the ATM switch router (HB-1)
in the Headquarters building and the ATM switch router (SB-1) in the Remote Sales building. Tosupport
signalling across this connection, a VP tunnel must be configured.
