Cloud Router는 경계 게이트웨이 프로토콜(BGP) 스피커 및 응답자 기능을 제공하는 분산형 완전 관리형 제품입니다.
Cloud Router는 Cloud Interconnect, Cloud VPN, 라우터 어플라이언스와 함께 작동하여 BGP 수신 및 커스텀 학습된 경로를 기반으로 VPC 네트워크에 동적 경로를 만듭니다.
Cloud Router와 Andromeda 네트워크 가상화 스택(Andromeda)(PDF 다운로드)은 함께 작동합니다. Andromeda는 모든 패킷 라우팅 및 전달 기능을 처리하고 Cloud Router는 상응하는 BGP 세션을 관리합니다.
Cloud Router는 패킷 라우팅 또는 전달 기능을 제공하지 않습니다.
IPv4 및 IPv6 프리픽스를 모두 교환하는 MP-BGP를 사용하는 IPv4 BGP 세션
IPv4 및 IPv6 프리픽스를 모두 교환하는 MP-BGP를 사용하는 IPv6 BGP 세션
다음 리소스에는 IPv6 BGP 피어링 및 IPv6 경로 교환이 지원되지 않습니다.
기본 VPN 터널
라우터 어플라이언스(Network Connectivity Center 일부)
Cross-Cloud Interconnect VLAN 연결
HA VPN 터널 또는 Dedicated Interconnect VLAN 연결에 IPv4 BGP 세션과 IPv6 BGP 세션을 동시에 구성할 수 있습니다. 두 BGP 세션을 동시에 구성하면 IPv4 BGP 세션은 IPv4 경로만 교환하고 IPv6 BGP 세션은 IPv6 경로만 교환합니다.

Andromeda handles all packet routing and forwarding capabilities,\nand Cloud Routers manage corresponding BGP sessions.\nCloud Routers don't provide packet routing or forwarding capability.\n\nGoogle Cloud products that use Cloud Router\n-------------------------------------------\n\nThe following table describes products that use Cloud Router:\n\nCloud NAT relies on Cloud Routers for control plane capabilities,\nbut not for BGP session management.\n\nKey features\n------------\n\nCloud Router offers the following features:\n\n- BGP session management, including support for [Bidirectional Forwarding\n Detection (BFD)](/network-connectivity/docs/router/concepts/bfd) and [MD5\n authentication](/network-connectivity/docs/router/how-to/use-md5-authentication).\n\n- [Advertised routes](/network-connectivity/docs/router/concepts/advertised-routes): advertise IP\n ranges to your network when you use a [supported\n product](#cloud-products-that-use-cloud-router).\n\n- [Learned routes](/network-connectivity/docs/router/concepts/learned-routes):\n Cloud Router uses routes received from BGP peers and custom learned\n routes to create [dynamic routes](/vpc/docs/routes#dynamic_routes) in\n VPC networks.\n\n- [BGP route policies](/network-connectivity/docs/router/concepts/bgp-route-policies-overview): BGP\n route policies let you set rules to filter BGP routes or modify BGP route\n attributes.\n\nIP protocols support\n--------------------\n\nCloud Router supports IPv6 route exchange through either of the\nfollowing:\n\n- BGP over IPv6\n- BGP over IPv4 using multiprotocol BGP (MP-BGP)\n\nFor information about advertising IPv6 prefixes, see [Advertising subnet IPv6\naddress ranges](/network-connectivity/docs/router/concepts/advertised-routes#ipv6-conditions).\n\nYou can create the following types of BGP sessions:\n\n- IPv4 BGP sessions that exchange only IPv4 prefixes\n- IPv6 BGP sessions that exchange only IPv6 prefixes\n- IPv4 BGP sessions using MP-BGP that exchange both IPv4 and IPv6 prefixes\n- IPv6 BGP sessions using MP-BGP that exchange both IPv4 and IPv6 prefixes\n\nIPv6 BGP peering and IPv6 route exchange aren't supported for the following\nresources:\n\n- Classic VPN tunnels\n- Router appliance (part of Network Connectivity Center)\n- Cross-Cloud Interconnect VLAN attachments\n\nYou can configure an IPv4 BGP session and an IPv6 BGP session simultaneously for\nan HA VPN tunnel or a Dedicated Interconnect\nVLAN attachment. When you configure both BGP sessions simultaneously, the IPv4\nBGP session only exchanges IPv4 routes, and the IPv6 BGP session only exchanges\nIPv6 routes.\n\nWhat's next\n-----------\n\n- To help build your network topology with Cloud Router, see\n [Best practices for Cloud Router](/network-connectivity/docs/router/concepts/best-practices).\n\n- To find definitions for Cloud Router terminology, see\n [Key terms](/network-connectivity/docs/router/concepts/key-terms).\n\n- [Establish BGP sessions](/network-connectivity/docs/router/how-to/configuring-bgp)\n\n- [Create an HA VPN to a peer VPN gateway](/network-connectivity/docs/vpn/how-to/creating-ha-vpn)\n\n- [Create HA VPN gateways to connect VPC\n networks](/network-connectivity/docs/vpn/how-to/creating-ha-vpn2)\n\n- [Create VLAN attachments](/network-connectivity/docs/interconnect/how-to/dedicated/creating-vlan-attachments)\n (Dedicated Interconnect).\n\n- [Configure multiprotocol BGP for IPv4 or IPv6 BGP sessions](/network-connectivity/docs/router/how-to/configuring-mp-bgp)"]]
