Internet 1 shows connected but is unreachable on warm MX84 Spare
The port on the MX84 shows a link light on both the MX84 and the switch its connected to but is unreachable. I've replaced all HW in the path with the exception of the MX84 and it still has the same symptoms.
Both the primary and the warm spare require their own access to the Internet. The warm spare can not connect through the primary to get to the Internet.
