APS Using a Container Interface with ATM Encapsulation Overview


M Series and T Series routers with ATM2 PICs automatically copy the parent container interface (CI) configuration to the specified children interfaces. All ATM configurations configured in a single location on the parent container interface are automatically copied to the children interfaces. Container interfaces do not go down during APS switchover, shielding upper layers (Layer 3 and above) from noticing the Layer 1 failures. This feature allows the various ATM features to work over the container ATM for APS.

For more information on container interfaces, see Understanding Container Interfaces.

Container ATM APS does not support interchassis APS.

MLPPP over ATM CI is not supported.
