Configuring a PVC on a Multipoint Subinterface
Creating a multipoint subinterface allows you to create a point-to-multipoint PVC that can be used as a
broadcast PVC for all multicast requests. To create a PVC on a multipoint subinterface, use the following
procedure beginning in global configuration mode:
SUMMARY STEPS
1. Router(config)# interface atm slot/subslot/port.subinterface multipoint
2. Router(config-subif)# ip address address mask
3. Router(config-subif)# no ip directed-broadcast
4. Router(config-subif)# pvc [name ] vpi /vci
5. Router(config-if-atm-vc)# protocol protocol {protocol-address | inarp} broadcast
6. Router(config-if-atm-vc)# inarp minutes
7. Router(config-if-atm-vc)# encapsulation {aal5mux protocol | aal5nlpid| aal5snap}
8. Router(config-if-atm-vc)# end

Purpose
Creates the specified point-to-multipoint subinterface on the given port on the specified
ATM SPA, and enters subinterface configuration mode, where:
• slot —Specifies the chassis slot number in the Cisco ASR 1000 Series Router
where the SIP is installed.
• subslot —Specifies the secondary slot of the SIP where the SPA is installed.
• port —Specifies the number of the individual interface port on a SPA.
• subinterface —Specifies the number of the subinterface.
Assigns the specified IP address and subnet mask to this subinterface.
(Optional) Disables the forwarding of IP directed broadcasts, which are sometimes used
in denial of service (DOS) attacks.
Configures a new ATM PVC by assigning its VPI/VCI numbers and enters ATM VC
configuration mode. The valid values for vpi /vci are:
• name —(Optional) An arbitrary string that identifies this PVC.
