The following is sample output from the show atm vc command when a vcd value is specified and there
is a PPP-over-ATM connection:

The following is sample output from the show atm vc command for IP multicast virtual circuits. The
display shows the leaf count for multipoint VCs opened by the root. VCD 3 is a root of a multipoint VC
with three leaf routers. VCD 4 is a leaf of some other router’s multipoint VC. VCD 12 is a root of a
multipoint VC with only one leaf router.

The following is sample output from the show atm vc command for an IP multicast virtual circuit. The
display shows the owner of the VC and leaves of the multipoint VC. This VC was opened by IP multicast.
The three leaf routers’ ATM addresses are included in the display. The VC is associated with IP group
address 10.1.1.1.
