Hi,

In advance thank a lot for your help.

My case

I'm running version 5.1 dev g3a9a03d.

Environment

I don't know what I'm doing wrong but here is my understanding. In case I vant to have L3VNI I have to create the vxlan/vni interface and the bridge attached to it. For isolation reasons I'd like to have a different VRF for each bridge.

So For my test I have:

17: vxlan_vni_101: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue master br_vni_101 state UNKNOWN group default qlen 1000
    link/ether 66:d0:4f:65:d5:f9 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::64d0:4fff:fe65:d5f9/64 scope link 
       valid_lft forever preferred_lft forever
18: br_vni_101: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue master vrf-101 state UP group default qlen 1000
    link/ether 66:d0:4f:65:d5:f9 brd ff:ff:ff:ff:ff:ff
    inet 192.168.100.200/24 scope global br_vni_101
       valid_lft forever preferred_lft forever
    inet6 fe80::64d0:4fff:fe65:d5f9/6 4 scope link 
       valid_lft forever preferred_lft forever

Which I create with its friends like this:

#!/bin/bash
vnis="101 102 103"
for vni in $vnis
  do echo configuring interfaces
     # Cretaing the VRF
        ip link add  dev vrf-${vni} type vrf table ${vni}
        ip link set vrf-${vni} up
     #
     # Cretaing the VLAN VNI
        ip link add vxlan_vni_${vni} type vxlan
          id ${vni} dstport 4789 local 192.168.10.1
          nolearning
        ip link set vxlan_vni_${vni} mtu 9000
        ip link set up dev vxlan_vni_${vni}
     #
     # attaching VXLAN VNI to VRF
        # ip link set dev vxlan_vni_${vni}  master  vrf-${vni}
     #
     # Creating Bridge For the VNI
        brctl addbr br_vni_${vni}
        brctl addif br_vni_${vni} vxlan_vni_${vni}
        brctl stp br_vni_${vni} off
        ip link set up dev br_vni_${vni}
     #
     # Assigning bridge to the VRF
        ip link set dev br_vni_${vni}  master  vrf-${vni}
     #
     # Adjusting iptables for the bridge
        iptables -A FORWARD -i br_vni_${vni} -o br_vni_${vni} -j ACCEPT
done

then I set the IP only on br_vni_101: ip addr add dev br_vni_101 192.168.100.200/24

The issue

but I only get one type 5 route (all this even before configuring the second router).

I don't get what I'm doing wrong.

Ok My bad I clearly misunderstood at the same time L2vpn evpn and the interaction between netlink and Zebra.

Now I get it when you have an L3vni it means you can advertise mac-ip or just ip.
If you have an L2vni then you can advertise only MAC addresses and links.

To determine this Zebra will check the bridge attached to the VXLAN VNI and if it handles any kind of L3, it will turn it from L2 to L3.

If you want to advertise mac-ip you have to use advertise-default-gw in the address-family l2vpn evpn

You are then supposed to be the VM gateway.

Sorry for the SPAM I'm closing this issue everything work like a charm so far.

Keep up the good work.

If you want to advertise type-2 routes you need to populate you l2vni fdb bridge because the interfaces'mac address attached to the l2vni bridge are not used in the bridge fdb directly (you need some traffic)

@flaurencin I was curious to know if you had the final FRR confguration you had to convert the Type 2 route into L3. We are attempting to do the same thing and would love to see what your final config was
