    Hi Guys,

     

    I see 'reject' when I issue the 'show route' command for a particular subnet.

     


    pav@XX> show route

    inet.0: 5 destinations, 5 routes (5 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both


    192.168.xx.xx/32 *[Local/0] 1w3d 02:50:10
    Reject

     

    Could you please let me know what does Reject mean ?

     

    Thanking you.

    Regards,

    Pavan Katakam

    It indicates that one of the interfaces configured with 192.168.x.x/X ip address is currently down. So when the device receives any packets destined to that interface ip, device will drop the packet and send destination network unreachable messages [meaning of reject] to the source system.

    Hi, Pavan

     

    Reject means that any packet matching that route will be dropped. One of the cases where I have seen this is when we configure proxy-arp. By any chance that address was configured under proxy-arp? if not, could you check where in your configuration is that address configured:

     

    # show | display set | match [address]
