In dem Dokumentationssatz für dieses Produkt wird die Verwendung inklusiver Sprache angestrebt. Für die Zwecke dieses Dokumentationssatzes wird Sprache als „inklusiv“ verstanden, wenn sie keine Diskriminierung aufgrund von Alter, körperlicher und/oder geistiger Behinderung, Geschlechtszugehörigkeit und -identität, ethnischer Identität, sexueller Orientierung, sozioökonomischem Status und Intersektionalität impliziert. Dennoch können in der Dokumentation stilistische Abweichungen von diesem Bemühen auftreten, wenn Text verwendet wird, der in Benutzeroberflächen der Produktsoftware fest codiert ist, auf RFP-Dokumentation basiert oder von einem genannten Drittanbieterprodukt verwendet wird. Hier erfahren Sie mehr darüber, wie Cisco inklusive Sprache verwendet.
Cisco hat dieses Dokument maschinell übersetzen und von einem menschlichen Übersetzer editieren und korrigieren lassen, um unseren Benutzern auf der ganzen Welt Support-Inhalte in ihrer eigenen Sprache zu bieten. Bitte beachten Sie, dass selbst die beste maschinelle Übersetzung nicht so genau ist wie eine von einem professionellen Übersetzer angefertigte. Cisco Systems, Inc. übernimmt keine Haftung für die Richtigkeit dieser Übersetzungen und empfiehlt, immer das englische Originaldokument (siehe bereitgestellter Link) heranzuziehen.
In diesem Dokument wird beschrieben, wie Sie Native Multicast in der SD-Access (SDA) Fabric überprüfen.
Cisco empfiehlt, dass Sie über Kenntnisse in folgenden Bereichen verfügen:
Die Informationen in diesem Dokument beziehen sich auf Geräte in einer speziell eingerichteten Testumgebung. Alle Geräte, die in diesem Dokument benutzt wurden, begannen mit einer gelöschten (Nichterfüllungs) Konfiguration. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die möglichen Auswirkungen aller Befehle kennen.
Dieses Dokument kann auch mit folgenden Hardware- und Softwareversionen verwendet werden:
SDA Native Multicast ist eine Form von Overlay-Multicast, das zur Übertragung von Multicast-Verkehr zwischen Fabric-Geräten verwendet wird und den Multicast-Verkehr in eine andere Multicast-Gruppe kapselt. Natives Multicast kann Multicast-Datenverkehr zwischen Quellen und Empfängern routen, die sich entweder im selben VLAN oder in einem anderen VLAN befinden (Multicast im selben VLAN kann geroutet werden). Multicast-Datenverkehr zwischen Quellen und Empfängern am selben Fabric Edge (FE) wird nicht mithilfe von Overlay-Multicast (VXLAN-Kapselung) weitergeleitet, sondern lokal von der FE geroutet. Natives Multicast kann Multicast-Datenverkehr nicht für Gruppen weiterleiten, die 224.0.0.0/24 oder einer Time To Live (TTL) =1 entsprechen. Diese werden durch Layer-2-Flooding (L2-Flooding) verarbeitet. Natives Multicast kann für die Weiterleitung von Any Source Multicast (ASM), Source Specific Multicast (SSM) oder einer Kombination aus beiden konfiguriert werden. Natives Multicast basiert auf Underlay-Multicast.
Hinweis: Plattformbefehle (Eingabe) können variieren. Der Befehl kann "show platform fed <active|standby>" oder "show platform fed switch <active|standby>" sein.". Wenn die in den Beispielen angegebene Syntax nicht analysiert wird, versuchen Sie es mit der Variante.
In dieser Topologie gilt Folgendes:
Es wird davon ausgegangen, dass Cisco Catalyst Center verwendet wird, um die SDA-Fabric mit den folgenden Einstellungen bereitzustellen:

In diesem Abschnitt wird das Protocol Independent Multicast (PIM) verifiziert. Dies beginnt mit der Validierung der (S,G)-Erstellung auf dem First Hop Router (FHR).
Die Multicast-Quelle 10.47.7.3 sendet UDP-Multicast-Pakete an 239.0.0.5. Überprüfen Sie, ob IP Device-Tracking (IPDT), Cisco Express Forwarding (CEF) und Reverse Path Forwarding (RPF) korrekt auf die Multicast-Quelle zeigen. Stellen Sie außerdem sicher, dass die Anycast Gateway SVI der PIM Designated Router (DR) für dieses Segment ist.
Verwenden Sie den Befehl "show device-tracking database address <IP-Adresse>", um sicherzustellen, dass ein gültiger IPDT-Eintrag vorhanden ist.
Edge-2#show device-tracking database address 10.47.7.3

Verwenden Sie den Befehl "show ip cef vrf <VN-Name> <IP-Adresse>", und stellen Sie sicher, dass die Multicast-Quelle direkt verbunden ist.
Edge-2#show ip cef vrf blue_vn 10.47.7.3
10.47.7.3/32
nexthop 10.47.7.3 Vlan1025
Verwenden Sie anschließend den Befehl "show ip rpf vrf <VN> <ip address>", um sicherzustellen, dass die RPF-Schnittstelle das VLAN ist, in dem sich die Quelle befindet, nicht LISP.

Verwenden Sie den Befehl "show ip pim vrf <VN name> interface vlan <vlan> detail | include DR|enabled", um zu überprüfen, ob der FE-Knoten der PIM DR für das Segment und der FHR ist.

Der Multicast-Empfänger sendet einen IGMP Membership Report/Join, um das Interesse am Empfang von Multicast-Datenverkehr anzugeben. Dadurch werden IGMP-Snooping- und IGMP-Gruppeneinträge auf dem Last Hop Router (LHR) erstellt. Verwenden Sie den Befehl "show ip igmp snooping groups vlan <VLAN-ID> <Gruppenzieladresse>" sowie den Befehl "show ip igmp vrf <VN-Name> groups <Gruppe>"

Es kann verschiedene Probleme geben, die verhindern können, dass die Multicast-Quelle oder der Multicast-Empfänger den Datenverkehr senden/empfangen. Dieser Abschnitt konzentriert sich auf die Validierung von Problemen, die sich sowohl auf die Multicast-Quelle als auch auf den Multicast-Empfänger auswirken können. Der Schwerpunkt liegt dabei auf Problemen, die nicht mit der Hardwareprogrammierung zusammenhängen.
Damit die FHR (S,G) sicherstellen kann, dass alle SISF, LISP, CEF und RPF gültig und korrekt sind, verwenden Sie den Befehl "show device-tracking database address <IPv4 address>"

Wenn es keinen gültigen Eintrag in SISF/IPDT gibt, führt dies zu keiner LISP-Datenbankzuordnung auf dem FHR, was dazu führt, dass CEF und RPF auf die Grenze(en) verweisen. Wenn die Multicast-Quelle Datenverkehr sendet, verweist RPF auf die falsche Schnittstelle, was zu einem RPF-Fehler führt. (S,G) wird nicht gebildet.

Um dies zu verhindern, behandeln Sie die Multicast-Quelle als einen unbeaufsichtigten Host, bei dem dieses Problem durch IP-Directed Broadcast, Flooding und statische SISF/IPDT-Bindungen behoben werden kann.
Die PIM-Registrierung ist ein Unicast-Paketfluss, der LISP/VXLAN wie jedes andere Unicast-Paket verwendet. Es gibt mehrere erforderliche Prüfungen, um sicherzustellen, dass die FHR die Multicast-Quelle ordnungsgemäß beim Anycast RP registrieren kann.
Stellen Sie zunächst sicher, dass der Anycast RP für den GDA richtig konfiguriert ist.

Erfassen Sie zur Validierung des FMAN RP zunächst die VRF-ID.

Verwenden Sie zum Validieren des FMAN FP-Objekts den Befehl "show platform software object-manager switch active f0 object <object ID> parent".
Zum Beispiel, um das Overlay (*,G) zu validieren
Edge-1#show platform software object-manager switch active f0 object 100880 parents
Object identifier: 100605
Description: ipv4_mcast table 2 (blue_vn), vrf id 2
Status: Done
Object identifier: 100878
Description: mlist 109
Status: Done
So validieren Sie das Overlay (S,G)
Edge-1#show platform software object-manager switch active f0 object 161855 parents
Object identifier: 100605
Description: ipv4_mcast table 2 (blue_vn), vrf id 2
Status: Done
Object identifier: 161854
Description: mlist 143
Status: Done
Die mlist ist eine Kombination aus eingehender Schnittstelle (IIF) und ausgehender Schnittstellenliste (OIL), die von der mroute in einem anderen Objekt getrennt ist. Verwenden Sie zum Validieren der mlist den Befehl "show platform software mlist switch active f0 index <index>".
