Configuration Help

[SheaO]

I have attached a diagram of what I would like the configuration to look like. What I'm trying to do is increase my bandwidth to my upstream provider. My question is; is the configuration in the diagram acceptable for this process. Currently I have one connection with the provider through the two 3850 switches and this works just fine. However, once these connections are placed in a LAG on either end, I can no longer learn mac addresses between the switches. Each switch learns the mac address of the directly connected router, but they are unable to see the router on the far end respectively. Essentially I'm looking for whether this is an acceptable configuration for what I'm trying to do or if there is something I'm missing. Thank you in advance for any assistance.

If the Upstream provide side and Nokia side Lag, you need to configure switch side also LAG, accessport for end device.

i would advise from north side to south side make all port in LAG allow VLAN 4001 and 4002 in the Port-channel ?

Ok. So if I'm understanding correctly, if its in a LAG on the far ends, it must be in a LAG in between as well. So I can't get around using port channels in between? I was hoping to avoid port channels as I would like for the Routers to be the only device that worry about load balancing my traffic. I will try the configuration with port channels and see if I can learn macs both ways. Thank you for the response.

Hello,

what type/model routers does your ISP have ?

[SheaO]

I am unsure. I know it is a Cisco device, but I'm not sure what kind.

I ended up using port channels. The issue of the Nokia not exchanging the mac address for the LAG turned out to be a software bug. Didn't want to leave this question open and hanging. Thanks all.
