Configuring Point-to-Multipoint PVP Connections
This section describes configuring point-to-multipoint PVP connections. Figure7-5 provides an
example of point-to-multipoint PVP connections.
Figure7-5 Point-to-Multipoint PVP Example
In Figure 7-5, cells entering the ATM switch router at the root point (the left side at interface
ATM4/0/0), 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
portA 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
ATM4/0/0 (VPI = 50), to the leaf point interfaces ATM 1/1/1 (VPI = 60), ATM3/0/0 (VPI = 70), and
ATM 3 /0 /3 (V PI = 8 0) (se e Figure 7-5):
Switch(config)# interface atm 4/0/0
Switch(config-if)# atm pvp 50 cast-type p2mp-root interface atm 1/1/1 60 cast-type
p2mp-leaf
Switch(config-if)# atm pvp 50 cast-type p2mp-root interface atm 3/0/0 70 cast-type
p2mp-leaf
Switch(config-if)# atm pvp 50 cast-type p2mp-root interface atm 3/0/3 80 cast-type
p2mp-leaf
