Release Information
Statement introduced before Junos OS Release 7.4.
Option for dscp and inet-prec introduced in Junos OS Release 8.4.
Option for dscp-ipv6 introduced in Junos OS Release 10.4R2.
Description
Apply a rewrite rule to MPLS packets only, and write the CoS value to MPLS headers only; or apply a rewrite rule to MPLS and IPv4 packets, and write the CoS value to MPLS and IPv4 headers.
Options
protocol-types can be one of the following:
- mpls—Apply a rewrite rule to MPLS packets and write the CoS value to MPLS headers.
- mpls-inet-both—Apply a rewrite rule to VPN MPLS packets with IPv4 payloads. On M120, M320, MX Series, and T Series routers (except T4000 routers), and EX Series switches, write the CoS value to the MPLS and IPv4 headers. On M Series routers, initialize all ingress MPLS LSP packets with IPv4 payloads with 000 code points for the MPLS EXP value, and the configured rewrite code point for IP precedence.
- mpls-inet-both-non-vpn—Apply a rewrite rule to non-VPN MPLS packets with IPv4 payloads. On M120, M320, MX Series, T Series routers, and EX Series switches write the CoS value to the MPLS and IPv4 headers. On M Series routers, initialize all ingress MPLS LSP packets with IPv4 payloads with 000 code points for the MPLS EXP value, and the configured rewrite code point for IP precedence.
