Configuring an EVPN Layer 3 gateway for MAC IP routes

Do the following to configure a Layer 3 gateway for MAC IP routes.

1. Configure the TCAM profile to support L3GW. Complete the steps in Configure the TCAM Profile for Layer 3 Gateway.
2. Create VLANs to be extended on the tunnel.
   

   vlan 1-4
   

3. Configure an EVPN instance.
   

   evpn r1
    route-target both auto
    rd auto
    vlan add 2-4
   

4. Configure BGP.
   

   router bgp
     local-as 100
       neighbor 98.0.0.1 remote-as 100
     address-family ipv4 unicast
     !
     address-family ipv6 unicast
     !
     address-family l2vpn evpn
       graceful-restart
       neighbor 98.0.0.1 encapsulation vxlan
       neighbor 98.0.0.1 activate

5. Configure a loopback interface.
   

   interface Loopback 1
    no shutdown
    ip ospf area 0
    ip address 1.2.3.4/32
   

6. Configure a tunnel interface.
   

   interface Ethernet 0/4
    ip ospf area 0
    ip proxy-arp
    ip address 98.0.0.2/24
    no shutdown
   

7. Configure the overlay gateway.
   

   overlay-gateway g1
   type layer2-extension
   ip interface Loopback 1
     map vni auto
   activate
