2 expressroute
create
- create a circuit
- Create a resource > Networking > ExpressRoute
- Circuit status is enabled
- Provider status
- will be Not provisioned initially.
- send the provider the value in the Service key field
- Create a peering configuration
- provider status is reported as Provisioned
- configure the routing for the peerings
- Connect a virtual network to an ExpressRoute circuit
- Azure virtual network gateway by using a subnet on one of your Azure virtual networks (entry point to network traffic)
- network security groups and firewall rules
- Up to 10 virtual networks can be linked to an ExpressRoute circuit (same geopolitical region)
models
- CloudExchange co-location
- Point-point Ethernet connection
- Any-to-any networks
integrate your wide area network (WAN) with Microsoft Azure
prerequisites
- ExpressRoute connectivity partner
- Azure subscription
- Microsoft Azure account that
can be used to request an ExpressRoute
- Office 365 subscription
- BGP sessions for routing domains have been configured
- Reserve several blocks of IP addresses in your network
NAT
private IP addresses used on-premises to public IP addresses
Microsoft will reject anything except public IP addresses through Microsoft peering.
-
Architecture
ExpressRoute partner: provides the edge service
(authorized and authenticated connection that operates through a partner-controlled router)
-
peering schemes
- private peering
- Azure IaaS and PaaS services deployed inside Azure virtual networks.
- can't access resources through their public IP address over a private peering.
- Microsoft peering
- to connect to Azure PaaS services, Office 365 services, and Dynamics 365

when
- Low-latency connectivity
- Accessing high-volume systems
- large number of users
- security
- Predictable performance
- connection dedicated and private
- latency is minimal, and throughput is greatly increased
- Built-in redundancy
- Across on-premises connectivity
- your data doesn’t travel over the public internet
