Configuring a single-VTEP static BD/VE Layer 3 gateway

Follow these steps to configure a single-VTEP static BD/VE Layer 3 gateway.

1. Configure the TCAM profile to support L3GW. Complete the steps in Configure the TCAM Profile for Layer 3 Gateway.
2. Configure a loopback address.
   

   interface Loopback 100
    no shutdown
    ip address 40.40.40.1/32

3. Configure an IP interface to be the interface of the VXLAN tunnel.
   

   interface Ethernet 0/10 
    ip proxy-arp
    ip address 50.50.50.1/24
    no shutdown

4. Create a VLAN.
   

   vlan 500

5. Configure an attachment circuit (AC) endpoint with a logical interface.
   

   interface Ethernet 0/20
    switchport
    switchport mode trunk-no-default
    logical-interface eth 0/20.500 vlan 500
    no shut

6. Configure a bridge domain (BD).
   

   bridge-domain 500 p2mp
    logical-interface eth 0/20.500
    pw-profile default
    bpdu-drop-enable
    local-switching

7. Configure the VTEP.
   

   overlay-gateway test
    type layer2-extension
    ip interface Loopback 100
    map vlan 500 vni 15000
    activate
    site VCS_2
    ip address 40.40.40.2  << This must be the remote-end loopback IP address and be reachable
    extend bridge-domain add 500

8. Configure VE over VXLAN by configuring a VE over the VLAN that is associated with VXLAN.
   

   vlan 500
    router-interface ve 500
   
   int ve 500
    ip address 15.15.15.1/24
    ipv6 address 1001::1/64 
    no shutdown
