What to Do Next
To verify the configuration and current status of all PVCs on a particular interface, you can also use the
show atm vc interface atm command.
Tip
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
DETAILED STEPS
PurposeCommand or Action
Creates the specified point-to-multipoint subinterface on the given port on the specified
ATM SPA, and enters subinterface configuration mode, where:
Router(config)# interface atm
slot/subslot/port.subinterface
multipoint
Step 1
• 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.Router(config-subif)# ip address
address mask
Step 2
(Optional) Disables the forwarding of IP directed broadcasts, which are sometimes used
in denial of service (DOS) attacks.
Router(config-subif)# no ip
directed-broadcast
Step 3
Configures a new ATM PVC by assigning its VPI/VCI numbers and enters ATM VC
configuration mode. The valid values for vpi /vci are:
Router(config-subif)# pvc [name
] vpi /vci
Step 4
• name —(Optional) An arbitrary string that identifies this PVC.
