If you execute the display mpls te tunnel-interface command immediately after an FRR protection
switch, you are likely to see two CR-LSPs in up state are present. This is normal because the
make-before-break mechanism of FRR introduces a delay before removing the old LSP after a new
LSP is created.
# Execute the display mpls lsp verbose command on Router B. You can see that the bypass tunnel
is in use.
