MPLS packet drops

[1pgordo]

I have two ASR9000 running 5.1.3. They are connected back to back using mpls protocol.


When i enter the command 'show mpls forwarding summary' i've got the following output:


        sh mpls forwarding summary
        …
        Pkts dropped:    46958
        ...
        Failed lookups:  447

Does anyone know wich could be the cause for the drops and the failed lookups?

Could you please paste the complete output. 

The usual cases when you see the packet drops is when the LSP is not complete or the LFIB doesnt knows where to forward the packet. THis can be seen when there are LDP neighbor flaps seen on the router.
