  • 1.  route appearing as hidden

    Posted 11-10-2023 22:30

    Hi, 

    I currently studdying for Junios certification JNCIS-SP, actually I'm doing lab to understand OSPF and BGP and route redistribution between them.

    Actually, I do not understand why router VMX6 in the next diagram si not adding 10.101.0.0/25 in the routing table.  The next hop for this network is 10.103.1.1 which is directly connected with VMX6 through GE-0/0/1.

    Here attached router configuration, diagram and routing table from VMX5 & 6.

    Any one may help me to understand why this route is not added to the routing table of VMX6 router.

    Thank you

    Hi Xine, 

    Hidden routes are due to unresolvable next-hop or a reject in a policy.

    I'm unable to see a policy on vMX6 to actually allow the routes inbound, so this is why I think the route may be hidden. 

    Could you please apply:

    # set protocols bgp group gr-MX5 neighbor 10.103.1.1 import pol-TOIMPORT


    See if this then allows the route to be seen in the routing-table?

    HTH,
