Static route unreachable after BIG-IP system reboot.


Static route exists in both kernel and LTM routing table but unable to ping the route after rebooting the BIG-IP system.


-- Add a static route. -- Issue a ping (works fine). -- Reboot the BIG-IP system. -- Issue a ping (cannot pint the route).


Workaround-1: Delete the IPv6 route entry and recreate the route by issuing the following commands in sequence: tmsh delete net route IPv6 tmsh create net route IPv6 network 2a05:d01c:959:8408::b/128 gw fe80::250:56ff:fe86:2065 interface internal Workaround-2: net route /Common/IPv6 { gw fe80::456:54ff:fea1:ee02 <-- Change this address to unicast address from 2a05:d01c:959:8409::/64 network interface /Common/Internal mtu 1500 network 2a05:d01c:959:8408::b/128 }
