S Series VXLAN LAB setup

[Andre_Brits_Kan]

Hi

I am busy playing with VXLAN between two S series switches in my LAB and have some problems.

The two S series switches connect to each other across a L3 routed network.
I have configured the VXLAN tunnel and that seems to be working fine.

VXLAN Setup for "SSA One":

interface tun.0.1 tunnel mode vxlan l2 tbp.0.1
tunnel source 172.16.1.1
no shutdown
exit

set tunnel logical-switch create name Switch1
set tunnel map logical-switch Switch1 keyword 111 vlan 100
set tunnel remote-vtep logical-switch Switch1 ip-address 172.16.1.2

set vlan egress 100 tbp.0.1 tagged
set vlan egress 100 ge.2.48 untagged (User Port)

VXLAN Setup for "SSA Two"

interface tun.0.1 tunnel mode vxlan l2 tbp.0.1
tunnel source 172.16.1.2
no shutdown
exit

set tunnel logical-switch create name Switch1
set tunnel map logical-switch Switch1 keyword 111 vlan 100
set tunnel remote-vtep logical-switch Switch1 ip-address 172.16.1.1

set vlan egress 100 tbp.0.1 tagged
set vlan egress 100 tg.1.24 untagged (User Port)

With the above configuration, devices connected to both S series switches in vlan 100 can ping each other.

-----------------------------------------------------------------------------------------

For the next part of my lab I would like to test routing from the remote site (SSA Two) to a network that is connected to "SSA one"

For this I added another vlan on "SSA one" and created a routed interface.

For users in vlan 100 (the VXLAN vlan) I have specified 192.168.100.1 (Vlan 100 interface on "SSA One") as the default gateway.
Clients connected the "SSA one" in vlan 100 can ping any device in vlan 10 and any device in vlan 10 can ping any device connected to "SSA one" in vlan 100.

The problem I have is with the remote clients.
The Remote clients connected to "SSA Two" in vlan 100 can ping any other device in vlan 100 (Both SSA one and SSA Two). These clients can also ping the Vlan 10 interface of "SSA One" (192.168.10.211), but they can not ping any other device in vlan 10.
The Vlan 10 devices can not ping any of the remote vlan 100 (SSA two) clients.

Why is this?

If I extend vlan 100 from "SSA One" to an external router that routes traffic for both Vlan 100 and Vlan 10 then every client can reach every other client.
Only when I use one of the terminating VXLAN SSA's for routing can the remote client not route out.

Hope this makes sense....

Could you try a default route instead of the network route on the bottom router
or
set the bottom clients default gateway to .211 instead of .1

and try again - I wonder whether that has any effect.....
