Example: Configuring DSCP Classification for VPLS
The following example configures DSCP classifier dscp_vpls on ATM interface at-4/1/1 with ether-vpls-over-atm-llc encapsulation. The classifier dscp_vpls is applied to the interface and the interface is listed in the VPLS routing instance vpls1 on the ingress PE router.
- Configure the ATM interface at-4/1/1.0 and the
encapsulation as ether-vpls-over-atm-llc:[edit]interfaces {at-4/1/1 {mtu 9192;atm-options {vpi 10;}unit 0 {encapsulation ether-vpls-over-atm-llc;vci 10.128;family vpls;}}}
- Configure the DSCP classifier dscp_vpls:[edit]class-of-service {classifiers {dscp dscp_vpls {forwarding-class expedited-forwarding {loss-priority low code-points 000010;}}}}
- Apply the classifier dscp_vpls to the ATM interface at-4/1/1.0:[edit]interfaces {at-4/1/1 {unit 0 {classifiers {dscp dscp_vpls;}}}}
- Include the ATM interface virtual circuit at-4/1/1.0 as part of the routing instance vpls1 configuration:[edit]routing-instances {vpls1 {instance-type vpls;interface at-4/1/1.0;route-distinguisher 10.255.245.51:1;vrf-target target:1234:1;protocols {vpls {site-range 10;no-tunnel-services;site vpls-1-site-1 {site-identifier 1;}}}}}
