Hi,

I just recently upgraded to 6.42.3 and I'm trying out the new configuration style without master ports. I have configured a bridge and added my target port to the bridge, then assigned an IP to the bridge. I can ping across the link just fine. But when I add OSPF or RIP to the bridge interface, nothing happens. I don't see a neighbor relationship form. Both devices are hEX running the same code. Any hints or suggestions are greatly appreciated.

d,
This turned out to be firewall related. There were new default rules that dropped the traffic.

Yes it's really common that some firewall rules drop the hellos for routing protocols, but I've seen some NAT rules that can do the same too by masquerading the packets into a different address.
