node along the MPLS TE tunnel returns an MPLS echo reply to the ingress due to TTL timeout. Thus, the
ingress can collect the information of each hop along the MPLS TE tunnel, so as to locate the failed node.
You can also use MPLS LSP tracert to collect information about each hop along the MPLS TE tunnel, such
as the label allocated.
To locate errors of an MPLS TE tunnel, perform the following task in any view:
Task Command
Use MPLS LSP tracert to locate errors of
an MPLS TE tunnel.
tracert lsp [ -a source-ip | -exp exp-value | -h ttl-value | -r
reply-mode |-t time-out ] * te interface-type interface-number
