18. Configure a static route for outbound traffic sent to VLAN 200.
OS10(config)#ip route 0.0.0.0/0 10.10.0.3
VTEP 4 Leaf Switch
14. Configure a dedicated VXLAN virtual network.
OS10(config)# virtual-network 500
OS10(config-vn-500)# vxlan-vni 500
OS10(config-vn-vxlan-vni)# exit
OS10(config-vn-10000)# exit
15. Configure an anycast gateway MAC address on the boder leaf VTEP. This MAC address must be different from
the anycast gateway MAC address configured on non-border-leaf VTEPs.
OS10(config)# ip virtual-router mac-address 00:02:02:02:02:02
16. Configure routing on the virtual network.
OS10(config)# interface virtual-network 500
OS10(conf-if-vn-10000)# ip vrf forwarding tenant1
OS10(conf-if-vn-10000)# ip address 10.5.0.234/16
OS10(conf-if-vn-10000)# ip virtual-router address 10.5.0.100
OS10(conf-if-vn-10000)# no shutdown
OS10(conf-if-vn-10000)# exit
17. Configure an externally connected VLAN.
OS10(conf)#interface vlan 200
OS10(conf-if-vlan)#ip address 10.10.0.2/16
OS10(conf-if-vlan)#no shutdown
OS10(conf-if-vlan)#exit
OS10(conf)#interface ethernet 1/1/7
switchport mode trunk
switchport trunk allowed vlan 200
18. Configure a static route for outbound traffic sent to VLAN 200.
OS10(config)#ip route 0.0.0.0/0 10.10.0.3
Example: VXLAN BGP EVPN—Symmetric IRB
The following VXLAN with BGP EVPN example uses a Clos leaf-spine topology to show how to set up an end-to-end VXLAN
with symmetric IRB. eBGP is used to exchange IP routes in the IP underlay network, and EVPN routes in the VXLAN overlay
network. All spine nodes are in one autonomous system—AS 101. All leaf nodes are in another autonomous system—AS 100.
● On VTEPs 1 and 2, access ports are assigned to the virtual network using a switch-scoped VLAN. EVPN for the overlay
VXLAN is configured using auto-EVI mode.
● On VTEPs 3 and 4, access ports are assigned to the virtual network using a port-scoped VLAN. The EVPN instance for the
overlay VXLAN is configured using manual configuration mode. The RD and RT are configured using auto mode.
● On all VTEPs, symmetric IRB is configured in EVPN mode using a unique, dedicated VXLAN VNI and EVPN RD and RT values
for each tenant VRF.
● The VLAN to an external network is configured only on VTEPs 3 and 4 in the VLT domain that serves as the border leaf
gateway.
NOTE:
In asymmetric IRB, you must configure all destination virtual-network subnets on each VTEP. Symmetric IRB
simplifies the VXLAN intersubnet configuration by reducing the number of required VNI configurations. In this example, VLT
domain 1 requires only VNI subnet 10.1.0.0/16; VLT domain 2 requires only VNI subnet 10.2.0.0/16. Symmetric IRB facilitates
the scaling of VXLAN virtual networks.
