    1. Don't strip QOS DSCP markings

      Azure vNets with ExpressRoute should support QOS markings. Ideally the Expressroute circuit should honour and prioritise packets with DSCP priorities set.

      If honouring DSCP is not possible then the values should at least be passed along and not be stripped out.

      We have Azure connected to our internal MPLS network via an Expressroute Exchange provider. (Our MPLS provider is not setup as a Network provider in Azure). Some of our remote sites have congested links however with QOS we ensure all business applications perform well.

      We are now moving some business applications into Azure and getting performance problems due to…

    2. Allow changing Billing Model for ExpressRoute from Unlimited to Metered with no downtime

      Currently you can change an ExpressRoute from Metered to Unlimited at any time without any disruption.

      You should also have the ability to go from Unlimited to Metered at any time without any disruption.

    3. BGP Filters on Private Peering

      Can we expand BGP filtering into Private peering? That will enable us filtering unnecessary traffic and also filter incoming onPrem networks into Azure VNET. Furthermore , that will provide summarisation of on Prem routes into VNETs thus less UDRs if you wanted to route all traffic via NVA

    4. Add location Specific BGP community for O365 routes

      O365 subnets over microsoft peering has the application specific community, but it is difficult to understand which location the subnet belongs to, so please add the location BGP community also with the Application BGP community

    5. Gray out existing connections so they can't be connected with ExpressRoute.

      Gray out existing connections so they can't be connected with ExpressRoute again and cause an outage.

      Failed to create connection 'ExpressRoute-EUS'. Error: The ExpressRoute connection for Nrp Resource Uri: https://eastus.network.azure.com/subscriptions/GUID/resourceGroups/expressroute-rg/providers/Microsoft.Network/connections/ExpressRoute-EUS2 already exists with a different Nrp Resource Uri:https://eastus.network.azure.com/subscriptions/GUID/resourceGroups/expressroute-rg/providers/Microsoft.Network/connections/US-East2

      "Do not allow redundant ER connection deployments to start. There is currently an error message but no block to starting a redundant connection deployment. This operation causes the circuit to lose connectivity."

    6. IPFIX/NetFlow export for traffic visibility

      Give ability for Express Route traffic to be visualized by a IPFIX/Netflow tool. i.e. Solarwinds NetFlow, LiveAction LiveNX etc.

    7. Separate O365 IP addresses from regional Azure IP address ranges

      I have an ExpressRoute with Public, Private and MS Peering. Currently Office 365 services are routed via the Public peering.

      When I activate a BGP community via route filter for MS peering (in my case the community 12076:51009 for Azure Central US), any users accessing 365 services from the Azure Central US region lose all connectivity. This is because the O365 services (such as login.microsoftonline.com or portal.office.com) are served out of Azure datacentres and the ranges overlap.

      Office 365 services must be authorised over MS peering, and the process is unnecessarily complicated and opaque. Until I manage to get this…

      Office 365 utilizes the Microsoft global Azure datacenter presence to provide Office 365 relates services to customers across the world. We are working to ensure long-term that the IP addresses are properly allocated to a given service and will align them to ensure that they do not overlap.

      If there are any issues with the current setup where some traffic does traverse the ExpressRoute public peering path, please raise a support request and one of engineers can review.

    8. express route

      Not sure if this is possible today, but I would like to see an option for public peering to have more granularity on the list of BGP communities so we only advertise services that a customer owns. As far as I can see today, through Microsoft peering we will see all public IP in the selected Azure region including those belonging to Microsoft Azure public services, a customer public IP address and any other customer public IP in that region. That means that lot of traffic is routed through public peering. Wouldn't be better to route traffic through Internet to…
