vPC Link Config (MLAG)

Beispiel eines Nexus C93180YC-FX3
Hier muss ein VPC Keepalive Link gesetzt werden. Dieser kann einfach 10G oder 25G sein.
Danach konfiguriert man den Peer Link über 2x 100G

VPC Keepalive

VPC Keepalive Link über 1x 10G oder 25G

Auf beiden Switches

feature vpc
feature lacp
feature interface-vlan
feature vtp

VPC Config auf Switch #1

vpc doamin 1
show vpc role

vrf context vpc-keepalive

interface Ethernet1/48
  description *** VPC-PEER-KEEPALIVE ***
  no switchport
  vrf member vpc-keepalive
  ip address 10.193.214.1/30
  no shutdown

VPC Config auf Switch #2

vpc doamin 1
show vpc role

vrf context vpc-keepalive

interface Ethernet1/48
  description *** VPC-PEER-KEEPALIVE ***
  no switchport
  vrf member vpc-keepalive
  ip address 10.193.214.2/30
  no shutdown

Test ob sich die Switches erreichen können
Ping von Switch #2 auf #1

ping 10.193.214.1 vrf vpc-keepalive

Auf Switch #1

vpc domain 1
peer-keepalive destination 10.193.214.2 source 10.193.214.1 vrf vpc-keepalive

Auf Switch #2

vpc domain 1
peer-keepalive destination 10.193.214.1 source 10.193.214.2 vrf vpc-keepalive

Kontrolle auf beiden Switches
