Configuring VXLAN BGP EVPN
In the above example, the option both is used to import and export routes associated with the Layer 3 VNI
50000. Specifically, the layer-3 routes will be advertised with route-target 100:50000 where 100 is the BGP
Autonomous system number and 50000 is the layer-3 VNI.
Associate the VRF VNI to a bridge-domain and associate a BDI to the customer VRF
(config) #
system bridge-domain add 2200
vni 50000
bridge-domain 2200
member vni 50000
interface bdi2200
vrf member coke
ip forward
no ip redirects
no shutdown
While the system bridge-domain command identifies the bridge domain IDs, the bridge-domain command
configures the specified bridge domain(s).
Add the Layer 3 VRF VNI to the overlay network and enable BGP reachability
(config) #
interface nve 1
host-reachability protocol bgp
member vni 50000 associate-vrf
Configure BGP, associate the customer VRF to BGP and enable L2VPN EVPN route distribution
(config) #
router bgp 100
vrf coke
address-family ipv4 unicast
Enable host/server facing BDI (and associate it to a VRF) for Layer 3 connectivity on the distributed
anycast gateway
(config) #
interface bdi200
vrf member coke
ip address 10.1.1.1/24
fabric forwarding mode anycast-gateway
no shutdown
VXLAN BGP EVPN Verification
For verification of MAC routes, refer these commands:
The following is sample output to verify that end host MAC addresses (local and remote) are added to the
MAC address table:
switch# show mac address-table dynamic
Note: MAC table entries displayed are getting read from software.
Use the 'hardware-age' keyword to get information related to 'Age'
Legend:
advertise l2vpn evpn
* - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link, E -
