Configuring a Point-to-Multipoint ATM1 or ATM2 IQ Connection

 

An ATM interface can be a point-to-point interface or a point-to-multipoint (also called a multipoint non-broadcast multiaccess [NBMA]) connection.

For ATM1 and ATM2 IQ interfaces, you can configure an NBMA ATM connection by including the following statements:

ip-address is the interface’s address. The address must include the destination prefix (for example, /24).

You can include this statement at the following hierarchy levels:

  • [edit interfaces interface-name unit logical-unit-number]

  • [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number ]

For each destination, include one multipoint-destination statement. address is the address of the remote side of the connection, and vci-identifier and vpi-identifier are the VCI and optional VPI identifiers for the connection.

When you configure point-to-multipoint connections, all interfaces in the subnet must use the same MTU size.
