Hi,
The forwarding-table looks ok and arp for the gateway is present too.
Only difference between node 0 & node 1, is that the passive node does not have a routing/forwarding table and uses the backup-router as gateway.
Did you try monitoring traffic on the interfaces to confirm if the packets are seen in and out on either end.
Also, I assume the mac addresses are present on the EX4300 after arp.
Cheers,
Ashvin
