    Express Connect:ModifyVirtualBorderRouterAttribute

    Last Updated:Aug 30, 2024

    Modifies the configuration of a virtual border router (VBR).

    Operation description

    • Only the owner of an Express Connect circuit can modify the VlanId parameter.
    • One VLAN ID of an Express Connect circuit cannot be used only by one VBR at the same time.
    • The VLAN ID of a VBR in the Terminated state is reserved for seven days and cannot be used by other VBRs. The VLAN ID can be used by other VBRs after 7 days.
    • You cannot set LocalGatewayIp, PeerGatewayIp, or PeeringSubnetMask for VBRs that do not belong to your Alibaba Cloud account.
    • Set PeeringSubnetMask to a subnet mask with 24 to 30 bits in length (255.255.255.0～255.255.255.252).
    • Set LocalGatewayIp and PeerGatewayIp to IP addresses that belong to the same CIDR block. For example, you can set LocalGatewayIp to 192.168.XX.XX, PeerGatewayIp to 192.168.XX.XX, and PeeringSubnetMask to 255.255.255.248.
