Make sure MLX has all port 4/4 tagged in all necessary vlans which are also present on Cat4500.

You are missing PIM configuration on Cat4500.

What is spanning tree configuration on MLX? Port eth 4/4 should also have "no route-only" command if it is running L3 code.

Match SPF throttle and referece bandwidth numbers between two switches.

Last but not least (this is optional)

Configure and hardcode router ID on both side.


router ospf 1

router-id xx.xx.xx.xx


ip router-id xx.xx.xx.xx
