Route maps for Azure Route Server are now available in
public preview, providing fine-grained control over inbound and outbound routing
across hybrid connections. Customers can manage routes advertised to and from
Azure Route Server BGP peerings with Network Virtual Appliances (NVAs),
ExpressRoute gateways, and VPN gateways in the same virtual network. Route-maps
provide the following capabilities:
- Route summarization: Summarize routes
when on-premises networks connect to the virtual network through ExpressRoute
or VPN.
- Route control: Control routes entering
and leaving Azure Route Server between on-premises networks, NVAs, and virtual
networks.
- Path selection: Modify BGP attributes
such as AS-PATH to make routes more or less preferred.
- Route tagging: Tag routes by using the
BGP Community attribute.
