Setting IPv6 DSCP and MPLS EXP Values Independently
date_range
13-Jan-21
On the M120, M320 with Enhanced III FPCs, MX Series 5G Universal Routing Platforms, and EX Series switches, you can set the DSCP and MPLS
EXP bits independently on IPv6 packets. To enable this feature, include
the protocol mpls statement at the [edit class-of-service
interfaces interface-name unit logical-unit-number rewrite-rules dscp-ipv6 rewrite-name] hierarchy
level.
You can set DSCP IPv6 values only at the ingress MPLS node.
The following limitations apply to this feature:
This feature is supported only on M120, M320 with Enhanced III FPCs, MX Series Ethernet Services routers, and EX Series switches.
MPLS packets entering another MPLS tunnel at the ingress node may mark only the EXP value if EXP rewrite rules are configured, but not the DSCP value in the IPv6 header.
This feature does not support MPLS packets generated by the Routing Engine.
The IP precedence field is not applicable for IPv6, and is not supported.
