Backup Tunnel : -
Group Status : -
Oam Status : -
NOTE:
If you perform 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.
Perform the display mpls lsp verbose command on Switch B. You can see that the bypass tunnel is in use.
