Probleemoplossing voor mVPN-profiel 14
Inhoud
Inleiding
Dit document beschrijft hoe u het multicast VPN (mVPN)-profiel 14 kunt oplossen binnen Cisco IOS® XR.
Voorwaarden
U moet kennis hebben van Multicast profile14 en zijn gedrag.
Vereisten
Cisco raadt aan de automatische detectie van MVPN BGP te configureren.
Ook wordt aanbevolen dat u deze onderwerpen kent:
- Profielen - 14
- Core Tree - mLDP
- Service - IPv4 VPN
- C-Overlay-signalering - BGP
- Automatische detectie - BGP
- Model - Partitie MDT P2MP met BGP AD
- Insluiting/doorsturen - MPLS
Gebruikte componenten
Dit document is niet beperkt tot specifieke software- en hardware-versies.
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u zorgen dat u de potentiële impact van elke opdracht begrijpt.
mLDP-concepten
Core Tree - mLDP
- Multipoint LDP = LDP + uitbreidingen
- P2MP-boom - door ontvanger aangedreven - Root geleerd van routing
- MP2MP-structuur -configuratiegestuurd -Root geconfigureerd
- Bescherming door MPLS TE of Loop-Free Alternate (LFA)
- Geen PHP -Top label identificeert de boom
- replicatie van mcast op de kernrouters
- FEC elementen hold: Type boom + Root + Ondoorzichtige waarde: (S, G), MDT nummer, LSP ID
mLDP
MP2MP LSP vs P2MP LSP
We hebben twee manieren om verkeer tussen de PE's te sturen.
1. MP2MP - een statische standaard-MDT wordt gemaakt tussen alle PE’s voor die bepaalde gebruiker, dit werkt alsof alle PE’s voor die gebruiker in hetzelfde LAN-segment waren aangesloten.
2. P2MP - wanneer een configureerbare drempelwaarde wordt bereikt, kan PE van de afzender een nieuwe LSP creëren zodat alleen de PE's die bij die communicatie zijn betrokken het verkeer zien, deze LSP wordt gecreëerd om onnodig verspilling van bandbreedte te vermijden die verkeer naar PE's verzendt die niet bij de stroom zijn aangesloten. Deze LSP maakt alleen voor een (S, G) ingang in het gebruikersnetwerk, als u verkeer dat de geconfigureerde drempel via een (*, G) ingang overschrijdt te verzenden, geen nieuwe P2MP wordt gecreëerd (het concept van PHP kan niet in dit scenario worden gebruikt wanneer het blad als wortel fungeert, anders weet het niet welke gebruiker dat verkeer behoort).
mLDP werkt met een concept als root, het is enigszins vergelijkbaar met een rendez-vous point in het PIM-SM scenario, maar onthoud dat in mLDP een PIM-vrije MPLS kern wordt genoemd, en PIM alleen is ingeschakeld in de gebruikersinterface.
In de MP2MP-boom zijn de wortels verantwoordelijk voor het ontvangen van het verkeer van een blad en het te repliceren naar alle direct verbonden buren.
Elke PE kan meer dan één gevormde wortel hebben, kiezen zij zijn actieve wortel die op metrisch wordt gebaseerd, als metrisch het zelfde is wordt het hoogste IP adres verkozen als wortel voor dat bepaalde PE.
In de P2MP-boom is de wortel altijd het apparaat dat het verkeer verstuurt (in dit document wordt de term root meer gebruikt om de MP2MP-boom van verwijzingen te voorzien, tenzij gespecificeerd).
P2MP en MP2MP
Recursief doorsturen
Recursive Forwarding betekent mLDP besturingsplane programma's alleen de (Downstream ID, Uitgaand etiket) naar het voorwaartse vlak. De Downstream-id is doorgaans de LDP-router-id van de downstream-knooppunt. Het voorwaartse vlak lost recursief de bereikbaarheid aan het stroomafwaartse apparaat op en neemt de daadwerkelijke uitgaande interface en de nexthop op. Recursive Forwarding maakt functies zoals ECMP/LAG load balancing, LFA, RSVP-TE bescherming enzovoort mogelijk. Helaas worden dit niet door alle platforms ondersteund.
Met niet-recursieve doorsturen bepaalt mLDP de uitgaande interface en NH naar de downstream router en expliciet programma's (Intf, NH, Uitgaand label) in het doorsturen vliegtuig.
Configuratie
Dit is de configuratie die vereist is voor mLDP:
mpls ldp
log
hello-adjacency
neighbor
nsr
graceful-restart
!
igp sync delay on-session-up 25
mldp
address-family ipv4
make-before-break delay 60 60
forwarding recursive
recursive-fec
Dit concept wordt uitgelegd in de sectie Problemen oplossen. Deze configuratie is vereist in de router MID en BUD.
Head/Root = Deze router heeft een multicast-bron aangesloten
Tail/Leaf = Deze router heeft Multicastontvangers
Bud = Deze router is in transit en heeft sommige ontvangers aangesloten
Mid = Deze router is in transit
Label Switch Multicast (LSM)/NG mVPN
- MPLS-insluiting gebruiken > Beheer en dataplaat delen met unicast
- Gebruik nieuwe core tree protocollen > mLDP, P2MP TE, BIER
- Fast ReRoute (FRR)
- Gebruik bewezen functionaliteit: Default en Data MDT
- Flexibelere designs per VPN
- Beheerbaarheid: het is niet nodig multicastgroepen per VPN/Default/Data MDT te volgen
BGP
AF IPv4-mVPN
AF IPv4 mVPN is toegevoegd om de NG profielen te kunnen ondersteunen. Het wordt ook wel de MCAST-VPN NLRI genoemd.
Er zijn twee belangrijke functies van deze adresfamilie:
- Automatische detectie (AD)
- Klantsignalering in overlay
Auto-Discovery betekent dat de PE-routers automatisch van elkaar leren. PE routers leren welke andere PE routers voor multicast voor VPN worden toegelaten. Dit vermijdt de behoefte om dit op elke PE router handmatig te configureren.
De gebruiker signalering in overlay is de signalering van (*, G) of (S, G) informatie, maar nu in BGP in plaats van PIM.
Bekijk afbeelding A om het overzicht van BGP AD IPv4 MVPN te zien.
Afbeelding A - BGP IPv4 AD MVPN
Er zijn twee belangrijke stukken informatie uitgevoerd door BGP in de AF IPv4 MVPN. Het eerste deel van de informatie bevindt zich in de NLRI zelf. Er is een getal van 1-7 dat het routetype voorstelt. Elk routetype heeft een specifieke functie. De eerste 5 worden gebruikt voor BGP-AD. Merk op dat Routetype 3 eigenlijk ook wordt gebruikt voor Data MDT (S-PMSI) signalering.
De laatste twee types, 6 en 7, worden gebruikt voor C-multicast signalering. Naast het routetype is er ook specifieke ingesloten routetype-informatie die betrekking heeft op de RD (als VPN-context wordt gebruikt), specifieke C-multicast-informatie (bron, groep) en het IP-adres (PE) van de maker.
Het tweede deel is het PMSI Tunnel Attribute (PTA). Deze PTA bevat informatie die betrekking heeft op de gebruikte kerntunnels. Het tunneltype geeft een aantal aan waarvan het core tree protocol gebruikt wordt om de tunnel te bouwen. De tunnelidentificatiecode is een verzameling velden die de tunnel op unieke wijze beschrijft door middel van specifieke core tree protocol velden.

Routetypen in AF IPv4 MVPN
In dit hoofdstuk wordt een overzicht gegeven van de verschillende routetypen en hun doel.
Intra-AS I-PMSI A-D router (type 1)
Doel: Het adverteren van de PE om deel te nemen aan MVPN voor een bepaalde VPN. Dit is BGP-AD.
Codering:
+-----------------------------------+

+-----------------------------------+
S-PMSI A-D router (type 3)
Doel
1. geadverteerd door de PE router, om het aan andere PE routers te signaleren dat het de Ingress PE voor een bepaalde C-(S, G) is en dat het over aan een MDT van Gegevens switches. De informatie van de kernboom nodig om PE routers te ontvangen sluit zich aan bij deze stroom wordt gecodeerd in PTA.
2. geadverteerd door een PE router, wijst het erop dat het aan een Verdeelde MDT model wil deelnemen. In dat geval zijn de velden Bron en Groep jokertekens (*,*).
Codering
+-----------------------------------+
| RD (8 octets) |
+-----------------------------------+
| Multicast Source Length (1 octet) |

| Source AS (4 octet) |
+-----------------------------------+
| Originating Router's IP Addr |
+-----------------------------------+
Als de A-D-route van het blad wordt geproduceerd die aan de route S-PMSI beantwoordt, dan ziet zijn NLRI als dit:
+-----------------------------------+
| Type (1 octet): 4 |
+-----------------------------------+
| Length (1 octet) |
+-----------------------------------+
| Type (1 octet): 3 |
+-----------------------------------+

1. Controleer of er alarmen op systeemniveau zijn op het gerapporteerde knooppunt (PE/ontvanger-PE/MID-router).
Show pfm location all
Show logging (Check for critical or major logs)
admin show alarm
2. Controleer de MPLS-kernconnectiviteit tussen de Head-end router en de Tail-end router.
3. Controleer de lokale connectiviteit van de multicast bron/ontvanger met aangesloten PE-routers.
4. Controleer de end-to-end connectiviteit tussen multicast bron en ontvanger.
5. Controleer de configuratie volgens de configuratiegids in het eerder genoemde document.
6. Basisverificatie van de systeemgezondheidscontrole:
- Controleer of er een systeemalarm is (
show pfm location all) - Controleer het geheugen en de CPU
show memory summary location all
show shmwin summary location all
show processes memory detail location all
show process cpu location <> - Controleer de interface en QoS-status
- Controleer de logboekregistratie bij kritieke meldingen of fouten
- Controleer op configuratiewijzigingen als gevolg van een waargenomen impact of probleem
