What is required for Layer 2 connections in Partner Interconnect?

For Layer 2 connections in Partner Interconnect, BGP (Border Gateway Protocol) configuration is essential. Partner Interconnect is used to establish private connectivity between your on-premises network and Google Cloud, utilizing a Layer 2 connection through a supported partner. In this context, BGP plays a crucial role in enabling the dynamic routing of packets between the networks.

With BGP, you can propagate routes efficiently, allowing for automatic adjustment when network changes occur, enhancing overall reliability and performance. It helps manage multiple routes and can quickly re-establish connections in case of failures, ensuring a robust network setup. Therefore, the requirement for BGP configuration is a strategic choice that adds flexibility and efficiency to the Layer 2 connections in Partner Interconnect.
