I have weird problem. I have some of the servers on RHEL-7.2, in that I am not able to add the route.
This route addition is something, which I have done thousand of time. The error I am getting is NO-Route to host which is kind of strange.
I am getting following error in the route addition #
route -A inet6 add 1203:900:223:3524:21::/112 gw 1203:270:713:3214:34::1 SIOCADDRT: No route to host
Following is the output of my device#

Searched a lot on this topic. Not able to find the resolution ROUTE-ADDITION-FAILURE. Nothing seems to be relevant on this topic. This issue is coming only to some of RHEL, not on all the machines.
In case, someone have seen this issue somewhere. Please respond, would be really helpful.
