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

Thank you
Xavier

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 ?

Le 27/09/2022 10:37, Xavier Jeannin a crit :

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
