Yes - the reason is that this router is a VM with two passthrough NICs.
The hypervisor is connected to both Force10 routers/switches with LACP, so the
VM needs to run linux bonding mode 2 to provide a bond0 interface to the VM.
Neighbourship then needs to be established to both routers on this
Hello,
you cannot use LACP between 3 devices. That is only possible if two of
those devices (Force10 routers/switches) are forming one logical device
(Cisco VSS, MEC, virtual PortChannel, HP IRF), I don't know if Force10
has something like that. If you do this however, those 2 routers will

It seems this is working if I disable the peer-routing feature on the Force10
routers - I’ll test a little more and get back with a tcpdump
Thanks.

Hi,
Thanks for your input - the Force10 switches have a VLT function (almost the
same as cisco vPC) which makes it possible to run LACP against two non-stacked
switches.
But this VLT stuff is only for L2, not L3, which means that basically servers
see the switches as one device through L2,
The Force10 manual states about peer-routing:
VLT unicast routing locally routes packets destined for the L3 endpoint of the
VLT peer.
So if this means that if LSAs for router1 are sent down the link in the port
channel connecting to router2, then router2 will respond instead of sending the

Anyway, it seems to be stable now - let me know if you would like the tcpdump
anyway.
No, it is not necessary.

This is supported on Linux.

I?m trying to use a bonded interface on linux to connect to two routers, one
router on each physical link, each with a /31 subnet.
Only one of the routers (Force10 S4810) forms adjacency with the linux host
(whichever comes first), the other gets stuck in EXSTART
until I shut/no shut the link,
