Reference Guide

When a virtual machine running in Server Rack 1 migrates to Server Rack 2, L3 packets for that VM are routed through the default
gateway.
The following examples show sample congurations of the core routers.
Sample conguration of C1:
• Congure peer routing:
C1(config)# vlt-domain 10
C1(conf-vlt-10)# discovery-interface ethernet1/1/1
C1(conf-vlt-10)# discovery-interface ethernet1/1/2
C1(conf-vlt-10)# peer-routing
C1(conf-vlt-10)# exit
• Congure VRRP on L2 links between core routers:
C1(config)# interface vlan 100
C1(conf-if-vl-100)# ip address 10.10.100.1/30
C1(conf-if-vl-100)# vrrp-group 10
• Congure VLT port channel for VLAN 100:
C1(config)# interface port-channel 10
C1(conf-if-po-10)# vlt-port-channel 10
C1(conf-if-po-10)# switchport mode trunk
C1(conf-if-po-10)# switchport trunk allowed vlan 100
C1(conf-if-po-10)# exit
