Multipoint support for ATM MIC with SFP

Devices with an ATM MIC on SFP can communicate with multiple devices through ATM links. With this multipoint support feature, ATM MIC can communicate with multiple Layer 3 peers in the ATM network. In earlier Junos OS releases, the ATM MIC communicates only with one Layer 3 peer.

On an ATM MIC, the following configurations are required for multipoint support:

• Configure the multipoint option at the [edit interfaces interface-name unit logical-unit-number] hierarchy level to communicate with multiple Layer 3 peers on ATM interface.
• Configure the multipoint-destination option with its corresponding vci at the [edit interfaces interface-name unit logical-unit-number family family address address] hierarchy to enable multipoint support on ATM interface.
  The Inverse-arp configuration option is an optional configuration to enable inverse ARP for multipoint-destination at the [edit interfaces at-fpc/pic/port unit logical-unit-number family family address address multipoint-destination address] hierarchy level. Only responding to inverse ARP request is supported. Generation of Inverse ARP is not supported.
