Expressroute Coexistence P2S
Hi We have an IPVPN ExpressRoute connection back to our MPLS. We also have a central Internet breakout from our MPLS, its quite small, only 300mb. we don't want to increase the bandwidth on t...
May consider the following workarounds:
1. Deploy a Separate VNG for P2S
- Create a new VNG in the same VNet (or peered VNet) with P2S enabled
- Use VNet peering to allow traffic between the P2S-connected clients and the ExpressRoute-connected resources
- Ensure gateway transit is enabled in peering settings
2. Use Route Tables to Direct Traffic
- Configure User Defined Routes (UDRs) to send traffic from P2S clients to on-prem via ExpressRoute
- Make sure BGP routes from ExpressRoute are propagated correctly
3. Avoid Virtual WAN for Now
- You're right — moving to Virtual WAN would require reprovisioning ExpressRoute, which is disruptive
- Stick with classic VNG + peering + UDRs for now
