Static VXLAN Conguration in a VLT setup
Conguration steps are covered below:
1 Both Gateway VTEPs need VLT congured.
• ICL port conguration
interface Port-channel 1
no ip address
channel-member TenGigabitEthernet 0/4-5
no shutdown
• VLT Domain Conguration
vlt domain 100
peer-link port-channel 1
back-up destination 10.11.70.14  this is ip address of the peer node
• VXLAN Instance Conguration
vxlan-instance 1 static
local-vtep-ip 14.14.14.14
no shutdown
vni-profile test
vnid 200
remote-vtep-ip 3.3.3.3 vni-profile test
• VLT Access port conguration
interface TengigabitEthernet 0/12
port-channel-protocol lacp
port-channel 30 mode active
interface Port-channel 30
no ip address
vxlan-instance 1
switchport
vlt-peer-lag port-channel 30
no shutdown
2 Congure loopback interface and VXLAN instances on both the peers.
• Congure loopback interface IP address on both peers with the same IPaddress.
interface Loopback 1
ip address 14.14.14.14/32
no shutdown
3 Congure VXLAN instance on access port for both the peers.
• Access Port Conguration
interface Port-channel 30
vxlan-instance 1
no ip address
channel-member TenGigabitEthernet 0/12
vlt-peer-lag port-channel 30
no shutdown
• VLAN Conguration
interface Vlan 200
vxlan-vnid 200 --- VNID for this VLAN
no ip address
tagged PortChannel 30
no shutdown
4 Congure routing protocol or static addresses to establish a L3 path to the remote VTEP.
