Configuring Layer 2 Circuit Cell-Relay Promiscuous Mode

By default, all incoming cells are mapped from a single virtual circuit (VC) to an external LSP. For ATM interfaces with Layer 2 circuit cell-relay transport mode and atm-ccc-cell-relay encapsulation, you can configure promiscuous mode. Promiscuous mode allows you to map all incoming cells from either an interface port or a virtual path (VP) to a single LSP without restricting the VCI number. You can map traffic from all 65,535 VCIs to a single LSP, or from all 256 VPIs to a single LSP. For promiscuous-mode configuration guidelines, see Configuring ATM Cell-Relay Promiscuous Mode.

Example: Configuring Layer 2 Circuit Cell-Relay Promiscuous Mode

Configure Layer 2 circuit cell-relay VP- and port-promiscuous mode:

VP-Promiscuous Mode

[edit interfaces]

at-0/1/0 {encapsulation atm-ccc-cell-relay;atm-options {pic-type atm2;cell-bundle-size 4;promiscuous-mode {vpi 0;}}unit 0 {encapsulation atm-ccc-cell-relay;point-to-point;vci 0.32;}}

Port-Promiscuous Mode

[edit interfaces]

at-0/1/0 {encapsulation atm-ccc-cell-relay;atm-options {pic-type atm2;promiscuous-mode;}unit 0 {allow-any-vci;}}

Configure Layer 2 circuit cell-relay VP-promiscuous and port-promiscuous modes on ATM MICs:

VP-Promiscuous Mode

[edit interfaces]

at-0/1/0 {atm-options {promiscuous-mode {vpi 1;}}unit 0 {encapsulation atm-ccc-cell-relay;vpi 1;}}

Port-Promiscuous Mode

[edit interfaces]

at-0/1/0 {encapsulation atm-ccc-cell-relay;atm-options {promiscuous-mode;}unit 0 {allow-any-vci;}}
