MPLS Link protection

‎10-31-2019 08:12 PM

What does it means when you see this, while checking the status of a protected LSP at the transit router (show mpls lsp transit extensive)? 

 

No suitable bypass with sufficient bandwidth

 

Thanks!

Hi Yasmin

 

Are these automatically generated bypass LSPs or individually/Manually configured bypass LSPs ??? 

 

In any case "No suitable bypass with sufficient bandwidth" means that the due to bandwith constraint the bypass in not up on this transit router. 

 

>check "show rsvp interface " on this transit router to check if there is any interface which has not bandwith avialable ?? 

> On the ingeress router chech the lsp for which link protection was enables to verify if the link protection ever came up ?? You should see "Link-protection Up" or "Link-protection Down" 

On ingress please collect: 

            "show mpls lsp name <lsp name>  extensive" 

          "show rsvp session extensive name <lsp name>"

I was using a static bypass LSP with plenty of bandwidth on the interfaces, but I was trying to use the same bypass LSP to protect too many LSPs going across the interface. I am now using dynamic bypass, with the max-bypass statement.
