Usage Guidelines
1. Place the router into Migration Mode only if it is still in the pre-IETF Standard (“Traditional”)
mode, and you want to begin upgrading its network to operate the IETF-Standard form of DS-TE.
2. Place the router into Liberal-IETF Mode only if its network is already in the Migration Mode, and
you want to complete the upgrade of that network so it will operate the IETF-Standard form of
DS-TE.
Examples In the following example, the router is configured to operate in Migration Mode:
Router(config)# mpls traffic-eng ds-te migration
migration A mode by which the router generates IGP and tunnel signalling according to the
pre-IETF standard, but adds TE-class mapping and accepts advertisement in both the
pre-IETF and the IETF-Standard formats.
ietf The “Liberal” IETF mode, by which the router generates IGP advertisement and tunnel
s
ignalling according to the IETF Standard and responds to TE-class mapping, yet also
accepts advertisement in both the pre-IETF-Standard and IETF-Standard formats.
