Cisco Nexus: Configuration VXLAN.

-

Configuration VXLAN on Cisco Nexus !!!
First: Legacy Method:
Connect between two servers by Trunk VLAN:

 Second: VXLAN Method:
Connect between two servers by VXLAN Tunnel.

 First Method:
        

 NXOS-L:
 vlan 2
 interface Ethernet1/2
    switchport access vlan 2
    spanning-tree port type edge
    no shutdown

 interface Ethernet1/1
   switchport mode trunk
   spanning-tree port type network
   no shutdown

NXOS-R:
vlan 2
interface Ethernet1/2
   switchport access vlan 2
   spanning-tree port type edge
   no shutdown
interface Ethernet1/1
   switchport mode trunk
   spanning-tree port type network
   no shutdown 



Result:



-------------------------------------------------------------------------------------------------

Second Method: VXLAN !!


NXOS-L:

feature ospf
 interface Ethernet1/1
    no switchport
    ip address 10.3.4.3/24
    ip router ospf 1 area 0.0.0.0
    ip ospf network point-to-point 
    no shutdown 

 interface loopback1
    ip address 3.3.3.3/32
    ip router ospf 1 area 0.0.0.0
router ospf 1
   router-id 3.3.3.3


NXOS-R:

feature ospf
interface Ethernet1/1
  no switchport
  ip address 10.3.4.4/24
  ip router ospf 1 area 0.0.0.0
  ip ospf network point-to-point 
  no shutdown 

interface loopback1
  ip address 4.4.4.4/32
  ip router ospf 1 area 0.0.0.0
 router ospf 1
   router-id 4.4.4.4

 


But ping between two servers not unreachable

Configure VXLAN:

NXOS-L:

feature vn-segment-vlan-based
feature nv overlay

vlan 2
   vn-segment 10002

interface nve1
  no shutdown
  source-interface loopback1
  member vni 10002
     ingress-replication protocol static
        peer-ip 4.4.4.4


NXOS-R:

feature vn-segment-vlan-based
feature nv overlay

vlan 2
   vn-segment 10002

interface nve1
  no shutdown
  source-interface loopback1
  member vni 10002
     ingress-replication protocol static
        peer-ip 3.3.3.3




 

Result:
