Configuring 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
