What Are the Reasons for the Static LSP's Failure in Becoming Up on Huawei Switch?

A static LSP is classified into the common static LSP, static LSP bound to the tunnel, and
static CR-LSP bound to the tunnel.
Huawei switches of V200R002C00 or later support MPLS TE.
Each node checks the command configuration of a common static LSP. The common
static LSP fails to be configured in any of the following situations:
– MPLS is not enabled globally.
– The static LSP with the same name exists.
– The static LSP with the same destination address and the same outbound interface (next hop) exists.
– The static LSP with the same incoming label exists.
– The configured next hop address is not the actual next hop address in the routing
table.
Each node checks the command configuration of a static LSP bound to the tunnel. The
static LSP bound to the tunnel fails to be configured in any of the following situations:
– MPLS is not enabled globally.
– MPLS TE is not enabled globally.
– On the ingress node, the bound tunnel does not exist or is not configured.
– The static LSP with the same name exists.
– The static LSP with the same destination address and the same outbound interface
(next hop) exists.
– The static LSP with the same incoming label exists.
– The configured next hop address is not the actual next hop address in the routing
table.
Each node checks the command configuration of a static CR-LSP bound to the tunnel.
The static CR-LSP bound to the tunnel fails to be configured in any of the following
situations:
– MPLS is not enabled globally.
– MPLS TE is not enabled globally.
– On the ingress node, the bound tunnel does not exist or is not configured.
– The static LSP with the same name exists.
– The static LSP with the same destination address and the same outbound interface
(next hop) exists.
– The static LSP with the same incoming label exists.
– The configured next hop address is not the actual next hop address in the routing table.
