Understanding DSCP Classification for VPLS
You can perform Differentiated Services Code Point (DSCP) classification for IPv4 packets on Ethernet interfaces that are part of a virtual private LAN service (VPLS) routing instance on the ingress provider edge (PE) router. This is supported on the M320 router with Enhanced type III FPC and the M120 router. On the ATM II IQ PIC, the ether-vpls-over-atm-llc encapsulation statement is required. On the Intelligent Queuing 2 (IQ2) or Intelligent Queuing 2 Enhanced (IQ2E) PICs, the vlan-vpls encapsulation statement is required. DSCP for IPv6 and Internet precedence for IPv6 are not supported.
In order to perform DSCP classification for IPv4 packets on Ethernet interfaces that are part of a VPLS routing instance on the ingress PE router, you must make sure of the following:
- The correct encapsulation statement based on PIC type is configured for the interface.
- The DSCP classifier is defined (default is allowed) at the [edit class-of-service classifiers] hierarchy level.
- The defined DSCP classifier is applied to the interface.
- The interface is included in the VPLS routing instance on the ingress of the PE router.
