Configure the Maximum Path Length

By default, each LSP can traverse a maximum of 255 hops, including the ingress and egress routers. To modify this value, include the hop-limit statement at the [edit protocols mpls], [edit protocols mpls label-switched-path lsp-path-name ], or [edit protocols mpls label-switched-path lsp-path-name (primary | secondary)] hierarchy level:

hop-limit number ; 

The number of hops can be from 2 through 255. (A path with two hops consists of the ingress and egress routers only.)
