From the krt async output, we see that 2600:6001:d1c:b8a6 is the IP due to which the error is seen

Solution

The static route config next-hop is pointing to 2600:6001:d1c:b8a6::. On correcting the IP to 2600:6001:d1c:b8a6::2, the retries cleared.

 

  route 2600:6001:f167::/48 next-hop 2600:6001:d1c:b8a6::;

      route 2600:6001:1ad3::/48 next-hop 2600:6001:a5c:210e::2;

    }

 

set routing-options rib inet6.0 static route 2600:6001:f167::/48 next-hop 2600:6001:d1c:b8a6::2
