Explanation

Verifying ARP with Cloud Router Status The gcloud compute routers get-status command checks the status of the Cloud Router, including its ARP entries. This helps confirm whether the Cloud Router has learned the ARP for the on-premises router, which is essential for establishing the BGP session. Subnet Mask Configuration When configuring the on-premises router's subinterface, a /31 subnet mask is required for point- to-point connectivity between your on-premises router and the Cloud Router. Incorrect subnet mask configurations are a common reason for BGP session failures.
