The SR-TE LSP configuration can accept an IPv6 address in the to and from parameters.
In addition, the MPLS path configuration can accept a hop index with an IPv6 address. The IPv6 address used in the from and to commands in the IPv6 SR-TE LSP, as well as the address used in the hop command of the path used with the IPv6 SR-TE LSP must correspond to the preferred primary global unicast IPv6 address of a network interface or a loopback interface of the corresponding LER or LSR router. The IPv6 address can also be set to the system interface IPv6 address. Failure to follow the preceding IPv6 address guidelines for the from, to, and hop commands causes path computation to fail with failure code ‟noCspfRouteToDestination".
A link-local IPv6 address of a network interface is also not allowed in the hop command of the path used with the IPv6 SR-TE LSP.
All other MPLS-level, LSP-level, and primary or secondary path-level configuration parameters available for an IPv4 SR-TE LSP are supported unless indicated otherwise.
