Pesan NOTIFICATION_RECEIVED muncul di log Cloud Route
Pesan NOTIFICATION_RECEIVED akan muncul di log Cloud Router saat Cloud Router telah menerima pesan NOTIFICATION dari peer BGP. Pesan NOTIFICATION adalah sinyal ke Cloud Router bahwa Cloud Router harus menghentikan sesi BGP.
Saat Cloud Router menerima pesan NOTIFICATION dari peer BGP-nya, Cloud Router akan menutup koneksi BGP dengan peer tersebut dan menghapus semua rute yang dipelajarinya.
Peer BGP dapat mengirim pesan NOTIFICATION karena berbagai alasan. Misalnya, peer mungkin mengirim pesan "Tahan Timer Berakhir".
Pesan CONFIG_DISABLED muncul di log Cloud Route
Pesan CONFIG_DISABLED menunjukkan bahwa Cloud Router sengaja menghentikan sesi BGP. Dengan menghentikan sesi BGP, Cloud Router mencoba untuk segera mengomunikasikan status error ke peer-nya.
Pesan ini dapat muncul karena salah satu alasan berikut:
Seorang pengguna telah menonaktifkan sesi BGP dengan menggunakan Cloud Router API,
konsolGoogle Cloud , atau Google Cloud CLI. Lihat Menonaktifkan atau menghapus sesi BGP.
Untuk sesi BGP yang disiapkan untuk Cloud VPN, tunnel VPN yang terkait
dengan sesi BGP belum membentuk IKE dan asosiasi keamanan
turunan (SA). Untuk memecahkan masalah konektivitas VPN, lihat Pemecahan masalah Cloud VPN.
Untuk sesi BGP yang disiapkan untuk Cloud Interconnect, lampiran VLAN tidak dikonfigurasi atau dalam status admin tidak aktif. Untuk memecahkan masalah ini lebih lanjut, lihat Pemecahan masalah dalam dokumentasi Cloud Interconnect.
Untuk sesi BGP yang mengaktifkan BFD, timer deteksi kontrol BFD di
Cloud Router telah habis masa berlakunya. Jika hal ini terjadi, sesi BGP akan
dihentikan. Untuk mengetahui informasi selengkapnya tentang status sesi BFD, lihat Pesan diagnostik
BFD dan status sesi.
Pesan LINK_DOWN muncul di log Cloud Route
Pesan LINK_DOWN muncul di log Cloud Router saat link antara router edge peering Google dan lampiran VLAN Anda untuk Cloud Interconnect tidak aktif. Router edge peering adalah peralatan jaringan yang dikelola oleh Google di dalam fasilitas kolokasi tempat Anda menyediakan koneksi Cloud Interconnect.
Pesan LINK_DOWN adalah sinyal bahwa status peer BGP yang terkait sedang
tidak aktif. Pesan ini hanya berlaku untuk sesi BGP berbasis Cloud Interconnect.

The `NOTIFICATION` message is a signal to Cloud Router that it\nshould stop the BGP session.\n\nWhen the Cloud Router receives a `NOTIFICATION` message from its BGP\npeer, Cloud Router closes the BGP connection with that peer and removes\nall its learned routes.\n\nThe BGP peer can send `NOTIFICATION` messages for a variety of reasons. For\nexample, the peer might send a \"Hold Timer Expired\" message.\n\n`CONFIG_DISABLED` message appears in Cloud Router logs\n------------------------------------------------------\n\nA `CONFIG_DISABLED` message indicates that Cloud Router has\nintentionally stopped the BGP session. By stopping the BGP session,\nCloud Router is attempting to immediately communicate an error state to\nits peer.\n\nThis message can appear due to any of the following reasons:\n\n- A user has disabled the BGP session by using the Cloud Router API,\n Google Cloud console, or the Google Cloud CLI. See [Disabling or removing BGP\n sessions](/network-connectivity/docs/router/how-to/disabling-removing-bgp).\n\n- For a BGP session set up for Cloud VPN, the VPN tunnel associated\n with the BGP session has not established an IKE and child security\n association (SA). To troubleshoot VPN connectivity, see [Cloud VPN\n troubleshooting](/network-connectivity/docs/vpn/support/troubleshooting).\n\n- For a BGP session set up for Cloud Interconnect, the VLAN\n attachment is not configured or is in an admin-down state. To troubleshoot\n the issue further, see\n [Troubleshooting](/network-connectivity/docs/interconnect/support/troubleshooting)\n in the Cloud Interconnect documentation.\n\n- For a BFD-enabled BGP session, the BFD control detection timer on the\n Cloud Router has expired. When this occurs, the BGP session is\n stopped. For more information on BFD session states, see [BFD diagnostic\n messages and session states](/network-connectivity/docs/router/concepts/bfd-states).\n\n`LINK_DOWN` message appears in Cloud Router logs\n------------------------------------------------\n\nA `LINK_DOWN` message appears in the Cloud Router logs when the link\nbetween the Google peering edge router and your VLAN attachment for\nCloud Interconnect is down. The peering edge router is networking\nequipment that is managed by Google inside the colocation facility where you\nhave provisioned your Cloud Interconnect connection.\n\nThe `LINK_DOWN` message is a signal that the corresponding BGP peer status is\ndown. This message applies only to Cloud Interconnect-based BGP\nsessions.\n\nWhat's next\n-----------\n\n- For more information about how to use Cloud Logging to monitor\n Cloud Router, see\n [View logs and metrics](/network-connectivity/docs/router/how-to/viewing-logs-metrics).\n\n- For additional support, see\n [Getting support](/network-connectivity/docs/router/support/getting-support).\n\n- For information about BGP session states, see\n [BGP session states](/network-connectivity/docs/router/concepts/bgp-states).\n\n- For information about diagnostic messages and session states related to\n Bidirectional Forwarding Detection (BFD), see\n [BFD diagnostic messages and session states](/network-connectivity/docs/router/concepts/bfd-states).\n\n- For issues related to using Cloud Router with Router appliance,\n see\n [Troubleshooting Router appliance](/network-connectivity/docs/network-connectivity-center/support/troubleshooting#troubleshooting-ra)\n in the Network Connectivity Center documentation."]]
