uhhh, please remove the ip address from the bvi1 and bun1.11,
as if it have an ip then it'll be exported as routed port...
also please remove the export-port bvi1 dynamic beforehand...
also a clear p4 p4 may be needed after doing so...
after that, if the bridge tables stays the same, it should work...

thank you
I will do it but If I suppress the address on bvi1 and bun1.11, how can I ping from DAV0001 to DAV0101?

I put here show bundle result

Hi

Thank you for your help

I just come back and put the IP address on the bviX interface instead of Bund1.X

Find below the show bridge1
It seems the mac learning works

No the from Bund1.11 and now bvi1 - ping does not work
Would you like I put a IPv4 @ on sdn4.11?



thank you
Xavier

hi,
sad to hear that.. does the bundling alone work? i saw a .11 subinterface in your configs, does that one ping?
also, does the mac learning at least work? could you please share sho bri 1 from both boxes?
thanks,
cs

Hello Csaba,

I apply your example but it does not work.
I am pretty sure, it is a misconfiguration     :-(

I put the configuration of the 2 switch attached and few show commands below

hi,
in general, bundles are created over physical interfaces and not subinterfaces...
so you have to bundle the sdns togeher, then configure the subinterface on top of the bundle interface...
much like this: http://sources.freertr.org/cfg/p4lang-rout018.tst
here you create a vlan 11 subinterface on top of sdn3 and sdn4...

Hello Csaba,

Thank         you for your email.
I want to collect our user traffic and put their traffic in a dedicated VLAN (then established the BGP peering between the RENATER bacbone PE and the client) - see picture below.

My understanding (I am certainly         wrong) is that I have to put the interface (sdnXX) in the bundle (not the sub interface) and it should be enough (see configuration attached).
But it does not work
I try also to put the sub-interface but no success.

Could you advice what type of configuration should I use for this use case?

The example available on http://docs.freertr.org/guides/reference/ are

conn-bundle01                                                     bundle of ethernet port
conn-bundle02                                                     bundle of serial port
conn-bundle03                                                     bundle of ethernet ports
conn-bundle04                                                     bundle of serial ports
conn-bundle05                                                     bundle over bridge
conn-bundle06                                                     bridge over bundle
conn-bundle07                                                     replicating bundle
conn-bundle08                                                     unreplicating bundle
conn-bundle09                                                     dejittering bundle
conn-bundle10                                                     loadbalancing bundle
conn-bundle11                                                     multichassis bundle
conn-bundle12                                                     backup bundle

Thank you
Regards
Xavier

hi,
lacp is there:
you have to configure it per member interface with both the lacp knob and the bundle-group knob...
the first one is just the protocol sender and you can omit if you do "mode on" on the remote side...
so that latter is the interesting part in the fastpath, and it's heavily tested with the dataplanes...

Hello

I allow myself to post again this request about LACP supporting trunk as if this would not be implemented, it will impact strongly our use case deployment.

Thank you

Hello

I am still stuck with the creation of LACP handling a trunk.
In the meantime, I review my configuration and see that "bridge-group 2" was not declared in P4 server after correction same pb.
This really something that block this work.

Any suggestion ?

Hello

I create a testbed on which (see picture attached):

         * the client is connected on a WEDGE (L2-PPN) at Layer 2 using Ethernet                 or VLAN
         * The WEDGE (L2PPN) should be connected to our backbone thanks to a bond of interfaces (LACP). The traffic on the LACP must be a VLAN trunk.

I see a strange behaviour and it is certainly due to how I configure it.

If I put the 2                 vlans (11-12) on the all interfaces taking part on the LACP, it does not work.
If                 I put the 1 vlan only on each interface of the taking part on the LACP, it                 works. But in this case the traffic should not be well shared between the LACP links.

I suspect I implement this use case not appropriately (see configuration attached + picture). Any suggestion?

Regards
Xavier
