[FROG] EVPN advertise static ARP entry

[Felipe Arturo Polanco]

Hi Donald,

I have an L2 working fine right now between two neighbors.
As soon as I add a veth interface into the same bridge where the Vxlan
interface is connected, that MAC address is advertised to the other
neighbor without any problem.
Also I see the entry in "bridge fdb show" command to send the broadcasts to
the other neighbor using its VTEP IP:

00:00:00:00:00:00 dev vxlan200 dst 198.18.0.12 self permanent

198.18.0.12 is the neighbor IP.

I have an L2 network 100.64.0.0/24
One router has 100.64.0.10 in the bridge and the neighbor has 100.64.0.11
in its bridge, they can communicate fine over VxLAN using the information
provided by EVPN.

I am adding an static entry in the ARP table of 100.64.0.10 but this entry
is not being propagated over EVPN
# arp -i br100 -s 100.64.0.2 62:e1:e3:18:24:f8  pub

The output in EVPN is not reflecting this new ARP entry:

# show evpn arp-cache vni 100
Number of ARPs (local and remote) known for this VNI: 3
IP                        Type   MAC               Remote VTEP
100.64.0.10               local  62:e1:e3:18:24:f8
fe80::60e1:e3ff:fe18:24f8 local  62:e1:e3:18:24:f8
100.64.0.11               local  22:b9:50:4c:b8:9c

And when I check the neighbor to see why it cannot ping this is showing up:

# arp -n
Address                  HWtype  HWaddress           Flags Mask
Iface
100.64.0.2                       (incomplete)
br100
100.64.0.10              ether   62:e1:e3:18:24:f8   C
 br100

If I manually add ARP entry into the neighbor(100.64.0.11) table it works.

Not sure if this answer this question Donald, this is pretty much where I
am right now.
