# On the tunnel interface, enable forwarding adjacency and the IS-IS process, and adjust the
metric of the tunnel interface so that the tunnel interface can become the outbound interface of
the second best IS-IS route. Take the configuration of P1 as an example. The configuration of
P3 is similar to that of P1 and is not mentioned here.

After the preceding configuration, run the display mpls ldp lsp command on PE1. The command
output shows that an LDP LSP is established. Take the display on PE1 as an example.

TOTAL: 0 Frr LSP(s) Found.
A '*' before an LSP means the LSP is not established
A '*' before a Label means the USCB or DSCB is stale
A '*' before a UpstreamPeer means the session is in GR state
A '*' before a DS means the session is in GR state
A '*' before a NextHop means the LSP is FRR LSP
Step 5 Configure IS-IS Auto FRR.
Enable IS-IS Auto FRR on P1 and P3, and disable the interfaces that connect P nodes to PE
nodes from becoming IS-IS LFA backup interfaces.
