OSPF to Cisco, broken broadcast and multicast hellos.


#1

Thinking we are hitting a bug but not sure.
Trying to get a OSPF neighbour relationship between Cisco 4948 and Vyos 1.1.1. OSPF relationship is coming up. Dead-time expires and neighour drops on the vyos side. I have performed a tcpdump and can confirm i’m seeing hello packets from cisco on 224.0.0.5.

I was trying this on a point-to-point OSPF network type, on ethernet link with a /31 vlan interface. Originally i thought maybe the /31 was broken and changed to a /30 and broadcast network type, however this had the same issue. I finally changed to non-broadcast for the network type and have a stable relationship with manally configured neighbours.

Intel 82574L Gigabit Network cards

I would like to get muulticast or broadcast working. Any ideas please?

seems like a bug in the Intel 82574L driver.

I have been testing with a X8 supermicro and was able to reproduce the issue using the same version of vyos, Cisco IOS, switch model and server model.

I was able to work around the issue by using a pci express dual port intel 868971 card that we had laying around.

Frustrating the onboard doesnt work. going to see if there any firmware upgrades…
