Azure Expressroute BGP peering

[nickdegroot]

Hi All,

We have a Maestro setup with 1 SG running on it. This SG has L2 connectivity to Azure Expressroute via our provider.

I'm struggling a bit on how to setup the redundant BGP peering.

It looks like Azure is sending 2 subnets within 1 VLAN

So there are 2 /30 subnets in 1 VLAN (VLAN 7). But on a Maestro setup i can't create 2 interfaces (which are needed due to the 2 /30 subnets )with the same VLAN ID.

Anyone has any experience with configuring the ExpressRoute BGP Peering on a Maestro setup?

The "provider" might be able to change the VLAN on one of the paths for you leveraging QinQ.

Thanks! Will discuss this with the provider!
