BGP dynamic routing¶
BGP routing dinamis men mengaktifkan self-service prefiks (private) jaringan untuk perangkat jaringan fisik yang mendukung BGP seperti router, sehingga menghilangkan ketergantungan konvensional pada rute statis. Fitur ini bergantung pada:ref:address scopes <config-address-scopes> dan membutuhkan pengetahuan tentang operasi mereka untuk penyebaran yang tepat.
BGP routing dinamis terdiri dari plug-in layanan dan agen. Layanan plug-in mengimplementasikan Jaringan ekstensi layanan dan agen mengelola BGP peering sesi. Seorang administrator cloud menciptakan dan mengkonfigurasi pembicara BGP menggunakan CLI atau API dan manual jadwal untuk satu atau lebih host menjalankan agen. Agen dapat berada pada host dengan atau tanpa agen layanan Networking lainnya. Advertisement awalan tergantung pada pengikatan jaringan eksternal ke speaker BGP dan ruang lingkup alamat rentang alamat IP eksternal dan internal atau subnet.
Catatan
Meskipun jaringan self-service umumnya menggunakan rentang alamat IP private (RFC 1918) untuk subnet IPv4, BGP routing dinamis dapat mengiklankan rentang alamat IPv4.
Contoh configuration¶
Contoh konfigurasi melibatkan komponen-komponen berikut:
- One BGP agent.
Salah satu ruang lingkup alamat yang berisi IP rentang alamat 203.0.113.0/24 untuk jaringan penyedia, dan alamat IP berkisar 10.0.1.0/24 dan 10.0.2.0/24 untuk jaringan swalayan.
- One provider network using IP address range 203.0.113.0/24.
- Three self-service networks.
- Self-service networks 1 and 2 use IP address ranges inside of the address scope.
Self-service jaringan 3 menggunakan rentang alamat IP yang unik 10.0.3.0/24 untuk menunjukkan bahwa speaker BGP tidak advertise prefiks luar lingkup alamat.
Tiga router. Setiap router menghubungkan satu jaringan swalayan ke jaringan provider.
- Router 1 contains IP addresses 203.0.113.11 and 10.0.1.1.
- Router 2 contains IP addresses 203.0.113.12 and 10.0.2.1.
- Router 3 contains IP addresses 203.0.113.13 and 10.0.3.1.
Catatan
Contoh konfigurasi mengasumsikan pengetahuan yang cukup tentang layanan Networking, routing, dan BGP. Untuk pengerahan dasar layanan Networking, konsultasikan salah satu Contoh pengerahan. Untuk informasi lebih lanjut tentang BGP, lihat RFC 4271.
Controller node¶
Dalam file neutron.conf, aktifkan konvensional lapisan-3 dan layanan routing dinamis BGP plug-in:
[DEFAULT] service_plugins = router,bgp
Agent nodes¶
Dalam file bgp_dragent.ini:
Configure driver.
[BGP] bgp_speaker_driver = neutron.services.bgp.driver.ryu.driver.RyuBgpDriver
Catatan
Agen saat ini hanya mendukung driver Ryu BGP.
Konfigurasi ID router.
[BGP] bgp_router_id = ROUTER_ID
Ganti ROUTER_ID dengan nomor 32-bit yang unik cocok, biasanya alamat IPv4 dari host menjalankan agen. Misalnya, 192.0.2.2.

Membuat dan mengkonfigurasi speaker BGP¶
BGP speaker advertises alamat IP next-hop untuk jaringan swalayan yang memenuhi syarat dan alamat IP mengambang untuk contoh menggunakan jaringan tersebut.

Speaker BGP memerlukan hubungan dengan jaringan provider untuk menentukan awalan yang memenuhi syarat. Asosiasi membangun daftar semua router virtual dengan gateway pada provider dan self-service jaringan di address scope yang sama sehingga speaker BGP dapat advertise prefixes jaringan self-service dengan sesuai router sebagai alamat IP next-hop. Mengasosiasikan speaker BGP dengan jaringan provider.
$ neutron bgp-speaker-network-add bgpspeaker provider Added network provider to BGP speaker bgpspeaker.
Verifikasi asosiasi jaringan provider dengan speaker BGP.

Catatan
Setelah membuat sesi peering, Anda tidak dapat mengubah nomor sistem otonomi lokal atau remote.
Jadwalkan speaker BGP untuk agen¶
Tidak seperti kebanyakan agen, BGP speaker memerlukan penjadwalan manual untuk agen. BGP speaker hanya membentuk peering sesi dan mulai prefix advertisement setelah penjadwalan untuk agen. Menjadwalkan speaker BGP untuk agen `` 37729181-2224-48d8-89ef-16eca8e2f77e``.

Prefix advertisement¶
BGP routing dinamis advertises prefixes untuk jaringan self-service dan host me-rute floating IP addresses.
Advertisement jaringan self-service membutuhkan memenuhi kondisi berikut:
Jaringan eksternal dan self-service berada dalam address scope yang sama.
Router berisi sebuah interface pada subnet self-service dan gateway pada jaringan eksternal.
BGP speaker associates with jaringan eksternal yang menyediakan gateway pada router.
BGP speaker memiliki atribut advertise_tenant_networks diatur ke True.
Advertisement dari alamat IP mengambang membutuhkan memenuhi kondisi berikut:
Router dengan alamat IP mengambang mengikat berisi gateway pada jaringan eksternal dengan asosiasi speaker BGP.
BGP speaker memiliki attribut advertise_floating_ip_host_routes diatur ke `` True``.
Operasi dengan Distributed Virtual Routers (DVR)¶
Dalam penyebaran menggunakan DVR, pembicara BGP mengiklankan (advertises) alamat IP mengambang dan jaringan swalayan berbeda. Untuk alamat IP mengambang, pembicara BGP mengiklankan agen gateway IP mengambang pada node komputasi yang sesuai sebagai alamat IP next-hop. Untuk jaringan swalayan menggunakan SNAT, pembicara BGP mengiklankan node DVR SNAT sebagai alamat IP next-hop.
Misalnya, pertimbangkan komponen-komponen berikut:
Sebuah jaringan operator menggunakan IP rentang alamat 203.0.113.0/24, dan mendukung alamat IP mengambang 203.0.113.101, 203.0.113.102, dan 203.0.113.103.
Sebuah jaringan swalayan menggunakan IP rentang alamat 10.0.1.0/24.
Gatewaya (gerbang) SNAT berada pada 203.0.113.11.
Agen gateway IP mengambang (satu per komputasi node) berada pada 203.0.113.12, 203.0.113.13, dan 203.0.113.14.
Tiga instance, salah satu per komputasi node, masing-masing dengan alamat IP mengambang.
$ neutron bgp-speaker-advertiseroute-list bgpspeaker
+------------------+--------------+
| destination | next_hop |
+------------------+--------------+
| 10.0.1.0/24 | 203.0.113.11 |
| 203.0.113.101/32 | 203.0.113.12 |
| 203.0.113.102/32 | 203.0.113.13 |
| 203.0.113.103/32 | 203.0.113.14 |
+------------------+--------------+
Catatan
DVR kekurangan dukungan untuk routing langsung ke alamat IP tetap melalui floating IP agent gateway port dan dengan demikian mencegah speaker BGP dari advertisement alamat IP tetap.
Anda juga dapat mengidentifikasi floating IP agent gateway di lingkungan Anda untuk membantu memverifikasi operasi speaker BGP.

IPv6¶
BGP routing dinamis mendukung mengintip melalui IPv6 dan advertisement IPv6 prefixes.
Untuk mengaktifkan mengintip melalui IPv6, membuat peer BGP dan menggunakan alamat IPv6 untuk `` peer_ip``.
Untuk mengaktifkan advertisement prefixes IPv6, membuat address scope dengan ip_version=6 dan speaker BGP dengan ip_version=6.
Catatan
DVR dengan fungsi IPv6 mirip dengan DVR dengan IPv4.
ketersediaan tinggi¶
BGP routing dinamis mendukung penjadwalan speaker BGP ke beberapa agen yang secara efektif mengalikan prefix advertisement untuk peer yang sama. Jika agen gagal, peer terus menerima advertisements dari satu atau lebih agen operasional.
Tampilkan tersedia agen routing dinamis.
