  • 1.  "show route forwarding-table" Output Meaning

    Posted 9 days ago

    Does anyone know what the trailing dash in the Netif column means?

    According to the manual

    Next-hop interface (Netif)

    Interface used to reach the next hop.

    Thank you, Scott . Do you happen to know what the dash after the interface name means?

    If it follows the key from the "show route" command it means "Last Active".   That's if.

    show route table mpls.0 label 20

    mpls.0: 118 destinations, 127 routes (118 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    Wouldn't be hard to lab to see if that's what it means.

    I don't think that fits because:

    • "Last active" means it's not currently active, and an inactive route shouldn't even be in the forwarding table to begin with 
    • None of the other symbols from that key seem to show up 
    • XML output shows the dash is appended to the interface name in the "via" field, rather than being its own field 
    • It seems likely that if the indicator symbols were intended to be the same as for the routing table output, so too would the output header been similar by way of including the key at the beginning
    • If it did indicate a last active route, the routing table would have a corresponding route listed with a "-" and it doesn't

    I don't off the top of my head, perhaps try 

    show route forwarding-table table blah destination 1.2.3.4 extensive | display xml

    and see if the XML tags give any indication/pointer as to what it is.

    Regards

    Great idea, but alas, no further information revealed. It's not a separate field; there's just a dash slapped at the end of the interface name for some reason.
