Terminologia
| EVPN |
Ethernet Virtual Private Network |
|
| VXLAN |
LAN virtuale estendibile (LAN) |
La VXLAN è progettata per superare i limiti intrinseci delle VLAN e dell'STP. Si tratta di uno standard IETF [RFC 7348] proposto per fornire gli stessi servizi di rete Ethernet di layer 2 delle VLAN, ma con una maggiore flessibilità. A livello funzionale, è un protocollo di incapsulamento MAC-in-UDP che viene eseguito come sovrimpressione virtuale su una rete sottostante di layer 3. |
| VTEP |
Endpoint del tunnel virtuale |
Questo è il dispositivo che esegue l'incapsulamento e il deincapsulamento |
| EVI |
Istanza EVPN |
L'istanza EVPN (EVI) è rappresentata dall'identificatore della rete virtuale (VNI, Virtual Network Identifier). Un EVI rappresenta una VPN su un router PE. Svolge lo stesso ruolo di VRF (IP VPN Routing and Forwarding), e alle EVI vengono assegnate RT (Route Targets) di importazione/esportazione |
| NVE |
Interfaccia virtuale di rete |
Interfaccia logica in cui si verificano l'incapsulamento e il deincapsulamento |
| VNI |
Identificatore di rete VXLAN |
Identifica in modo univoco ogni subnet o segmento di layer 2. Esistono due tipi di VNI: Simmetrico (L2VNI): i VTEP hanno lo stesso VNI Asimmetrico (L3VNI): i VTEP non hanno lo stesso VNI e vengono instradati tramite un unico VNI comune. |
| INSETTO |
Broadcast, Unicast sconosciuto, Multicast |
Il traffico BUM viene inviato tramite il gruppo Mcast associato al VNI nella configurazione NVE. |
| TRM |
Multicast con routing tenant |
Soluzione basata su BGP-EVPN che consente il routing multicast tra le origini e i ricevitori connessi su VTEPS in fabric VxLAN [RFC7432]. Sono disponibili due tipi L2TRM (Layer 2 TRM) e L3TRM (Layer 3 TRM) |
| MDT |
Albero distribuzione multicast |
L'albero multicast è stato costruito tra i VTEP per l'incapsulamento e il tunneling del traffico multicast del tenant. |
| PVLAN |
VLAN privata |
Partiziona il dominio di broadcast Ethernet di una VLAN in sottodomini, consentendo di isolare le porte dello switch. |
| MIB |
Base informazioni di gestione |
A Oggetto monitoraggio SNMP (Simple Network Management Protocol) |
| PIM-BIDIR |
Protocollo Multicast Bidirezionale Indipendente |
Tipo di PIM in cui il traffico viene inoltrato solo lungo una struttura condivisa che si basa sul punto di incontro (RP) del gruppo. |
| VFI |
Istanza di inoltro virtuale |
Porta bridge virtuale in grado di eseguire funzioni di bridging native, ad esempio l'inoltro, in base all'indirizzo MAC di destinazione, all'apprendimento e all'invecchiamento dell'indirizzo MAC di origine e così via. |
| IRB |
Routing e Bridging integrati |
abilita una VPN di livello 2 e una VPN di livello 3 che consente agli host terminali della sovrapposizione di comunicare tra loro all'interno della stessa subnet e tra subnet diverse all'interno della VPN. |
| IMET |
Tag Inclusive Multicast Ethernet |
chiamata anche BGP Route Type 3 (RT3), per il rilevamento automatico dei peer remoti per configurare i tunnel BUM sulla VXLAN. Le route IMET trasportano i VNI remoti (in uscita) pubblicizzati dai peer remoti, che possono essere diversi dal VNI locale. Queste VNI remote sono chiamate VNI assegnati in downstream. |
| DAG |
Distributed Anycast Gateway |
Funzione gateway predefinita su tutti i VTEP. Lo stesso IP gateway risiede su tutti i VTEP e consente la mobilità nel fabric. |
| IR(B) |
Routing integrato (e bridging) |
Abilita una VPN di livello 2 e una VPN di livello 3 che consente agli host terminali della sovrimpressione di comunicare tra loro all'interno della stessa subnet e tra subnet diverse all'interno della VPN. |
| RNH |
Hop successivo remoto |
Il VTEP remoto |
| RPF |
Inoltro percorso inverso |
Percorso unicast di nuovo all'origine. I pacchetti multicast in ingresso non vengono accettati o inoltrati a meno che non ricevano lo stesso percorso della tabella di routing unicast. (casi di utilizzo 'ip multicast' esclusi). |
| RP |
Punto di rendering |
Ruolo svolto da un dispositivo in modalità sparse PIM. Punto di incontro comune per origini e ricevitori multicast. |
Esempio di rete
Topologia EVPN VXLANv6 Greenfield
Verifica (Greenfield o Dual-stack)
Prima di eseguire la risoluzione dei problemi per flusso di traffico, è necessario verificare le informazioni a livello di topologia EVPN VXLANv6 per garantire il corretto funzionamento. In questa sezione vengono illustrati i comandi di verifica per entrambe le distribuzioni. Selezionare i comandi di verifica applicabili in base alla distribuzione.
Connettività Underlay
Verificare la connettività IPv6 underlay tra VTEP e Spine (per Greenfield VXLANv6 è sufficiente verificare la connettività IPv6 underlay).

Nota: nel caso di route IMET dual-nexthop, l'attributo del tunnel PMSI nella route importata EVI ha come identificatore del tunnel l'indirizzo nexthop primario. Il protocollo BGP sostituisce tale indirizzo con l'indirizzo nexthop secondario dell'attributo tunnel encap se la preferenza locale è quella della famiglia di indirizzi nexthop dell'endpoint del tunnel. Nell'esempio, sebbene BGP mostri Tunnel Endpoint come 10.2.2.2, durante l'installazione in L2RIB, viene sostituito con 2001:DB8:2:2. Questa operazione viene eseguita perché BGP non modifica la voce dell'attributo nella tabella degli attributi.

BUM Traffic Forwarding (replica multicast)
In questa sezione viene illustrato un esempio di risoluzione del traffico BUM da VTEP1 a VTEP2 in EVI 2 dove il tipo di replica è configurato come statico.
Verificare che il tipo di replica sia impostato su Static per la EVI in EVPN Manager su entrambi i VTEP
-
Entrambi i VTEP devono essere configurati con lo stesso gruppo multicast inferiore per la stessa EVI. Le informazioni sul gruppo multicast sottostante provengono da NVE. Controllare la configurazione dell'interfaccia NVE se non è impostata correttamente.

Inoltro unicast tra VTEP (stessa VLAN tramite L2VNI)
In questa sezione viene fornito un esempio per la risoluzione dei problemi relativi al traffico unicast:
- dall'host H11 collegato al VTEP1 sulla VLAN 11 (con indirizzo MAC abb.0000.0011 e IP 192.168.11.11)
- per l'host H31 collegato al VTEP3 sulla VLAN 11 (con indirizzo MAC abb.0000.0031 e indirizzo IP 192.168.11.31).
Verificare che ARP per l'indirizzo IP di destinazione sia stato risolto nell'host di origine
-
I pacchetti ARP vengono gestiti come parte del traffico BUM nell'infrastruttura EVPN. Se ARP non viene risolto su un host, utilizzare i passaggi per la risoluzione dei problemi relativi all'inoltro del traffico BUM EVPN per il tipo di replica configurato appropriato utilizzato nella rete.

Inoltro unicast tra VTEP (VLAN diverse tramite L3VNI)
In questa sezione viene illustrato un esempio di risoluzione dei problemi relativi al traffico unicast
- dall'host H11 collegato al VTEP1 sulla VLAN 11 (con indirizzo MAC abb.000.0011 e IP 192.168.11.11)
- per l'host H22 collegato al VTEP2 sulla VLAN 12 (con indirizzo MAC abb.000.0022 e indirizzo IP 192.168.12.22)
Verificare che l'ARP per il gateway predefinito sia stato risolto nell'host

Handoff EVPN tra foglia di bordo e router VPN MPLS
Questa sezione è applicabile sia per l'handoff L3VPN che per l'handoff Multi VRF (VRF lite/PE-CE)
Verificare il prefisso IP sul router VPN remoto (R1) annunciato a Border-Leaf (vtep3) nell'infrastruttura VPN
- Il nodo VPN R1 ha un underlay MPLS, è un singolo stack. Il nodo Foglia-Bordo Leaf3 e il resto del fabric EVPN possono essere in modalità stack singolo o stack doppio,
Verificare quanto segue se si verifica un problema di traffico con EVPN Route-type 5 (RT5):
Passaggio 1. Conferma route RT5 nella tabella globale EVPN
Passaggio 2. Verificare che il percorso sia importato in VRF
- È necessario che l'RT di importazione sia configurato per il VRF.
- Unione di Route-Target (RT) per uno scenario di handoff su border-leaf/border-spine
- Verificare che la configurazione della VPN BGP "annuncio evpn l2vpn" sia presente nella vrf della famiglia di indirizzi
- Verificare che la configurazione di importazione venga eseguita correttamente sull'handoff L2vpn evpn famiglia di indirizzi e vpnv4/vpnv6 ror L3VPN (sul nodo di bordo), come mostrato di seguito:

Passaggio 3. Controllare lo stato VTEP locale con questo comando
VTEP3#show bgp l2vpn evpn local-vtep vrf red
Local VTEP vrf red:
Protocol: IPv4
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
Protocol: IPv6
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
Passaggio 4. Verificare che l'RNH (Remote Nexthop) sia installato per il VRF.
- RNH garantisce l'adiacenza del percorso installato nel RIB.
- BGP installa la route RT5 nella tabella VPN BGP, che viene quindi installata nella tabella IP VRF corrispondente.
- L’adiacenza del nexthop installato è assicurata dai parametri del VTEP remoto (come RMAC, eVNI e RTEP). Il valore RTEP corrisponde all'indirizzo di destinazione successivo della route.
- BGP installa l'RNH direttamente in L3-EVPN/NVE.
Se RNH non è corretto, l'immissione CEF per le route non avrà un'adiacenza completa.
- In uno scenario a doppio stack, è necessario controllare se il nexthop per il router e il protocollo RNH/RTEP (endpoint del tunnel remoto) sono gli stessi.
Quando una route non è installata o la route installata ha un'adiacenza incompleta, verificare i parametri RNH e stabilire una correlazione con la configurazione nel nodo locale e con il valore dei parametri nella route.
VTEP3#show bgp l2vpn evpn rnh vrf red
Remote VTEP entries for vrf red:
Protocol: ipv4
[VNI / RMAC ADDRESS / VTEP-IP / Installed]

[30000 / AABB.CC81.F500 / 2001:DB8:1::2 / yes]
Passaggio 5: verificare lo stato peer NVE
- Lo stato peer NVE è attivo quando BGP riceve una route dal peer remoto e viene installato correttamente nel sottosistema RIB e L3-EVPN/NVE.
