MPLS Global Tasks

In a typical network, you perform only the first task. You might also perform the optional configuration tasks, but typically do not need to do so.

Enable MPLS on a virtual router. host1(config)#mpls
(Optional) Configure the time-to-live field placed in the MPLS header when a label is first added to an IP packet.host1(config)#mpls ip propagate-ttl forwarded
(Optional) Configure the tunneling model for differentiated services. See Configuring MPLS and Differentiated Services for more information and command descriptions. host1(config)#mpls tunnel-model uniform
(Optional) Specify whether to use the TOS value (the default condition) or the UPC value of the packet as the value of the EXP bits when the router acts as an LER.host1(config)#mpls copy-upc-to-exp
(Optional) Specify whether the EXP bits for VPN MPLS labels can be modified by EXP bit mapping or by policy for differentiated services. host1(config)#mpls preserve-vpn-exp
(Optional) Specify whether to create dynamic IP interfaces on top of MPLS major interfaces and optionally what profile to use for them. host1(config)#mpls create-dynamic-interfaces ip on-major-interfaces profile v4intf
