This section describes configuring point-to-multipoint PVP connections.
Figure 7-5
provides an
example of point-to-multipoint PVP connections.
Figure 7-5
Point-to-Multipoint PVP Example
In
Figure 7-5
, cells entering the ATM switch router at the root point (the left side at interface
ATM 4/0/0), VPI = 50, are duplicated and switched to the leaf points (output interfaces), on the right side
of the figure.
To configure point-to-multipoint PVP connections, perform the following steps, beginning in global
configuration mode:
To configure the point-to-multipoint PVP connections using the
atm pvp
command, the root point is
port A and the leaf points are port B.
Note
The row index for
rx-cttr
and
tx-cttr
must be configured before using this optional parameter. See
Chapter 9, “Configuring Resource Management.”
Examples
The following example shows how to configure the root-point PVP on ATM switch router interface
ATM 4/0/0 (VPI = 50), to the leaf point interfaces ATM 1/1/1 (VPI = 60), ATM 3/0/0 (VPI = 70), and
ATM 3/0/3 (VPI = 80) (see
Figure 7-5
):
