Static VXLAN tunnel state


Hello!

I am testing Cumulus static VXLAN configuration.
I use this guide - https://docs.cumulusnetworks.com/display/DOCS/Static+VXLAN+Tunnels.

My config looks like this:

leaf1:
interface lo
address 1.1.1.1/32
interface eth0
address dhcp
interface swp1
bridge-access 10
interface swp3
ipv6 nd ra-interval 10
no ipv6 nd suppress-ra
interface bridge
bridge-ports swp1 vni-10
bridge-vids 10
bridge-vlan-aware yes
interface vni-10
bridge-access 10
mstpctl-bpduguard yes
mstpctl-portbpdufilter yes
vxlan-id 10
vxlan-local-tunnelip 1.1.1.1
vxlan-remoteip 4.4.4.4 router bgp 65001 bgp router-id 1.1.1.1 coalesce-time 1050 neighbor swp3 interface remote-as external address-family ipv4 unicast network 1.1.1.1/32 neighbor swp3 soft-reconfiguration inbound
spine1:
interface lo
address 2.2.2.2/32
interface eth0
address dhcp
interface swp3
ipv6 nd ra-interval 10
no ipv6 nd suppress-ra
interface swp4
ipv6 nd ra-interval 10
no ipv6 nd suppress-ra

router bgp 65000
bgp router-id 2.2.2.2
coalesce-time 1100
neighbor swp3 interface remote-as external
neighbor swp4 interface remote-as external
address-family ipv4 unicast
network 2.2.2.2/32
neighbor swp3 soft-reconfiguration inbound
neighbor swp4 soft-reconfiguration inbound

leaf2:
interface lo
address 4.4.4.4/32
interface eth0
address dhcp
interface swp1
bridge-access 10
interface swp4
ipv6 nd ra-interval 10
no ipv6 nd suppress-ra
interface bridge
bridge-ports swp1 vni-10
bridge-vids 10
bridge-vlan-aware yes
interface vni-10
bridge-access 10
mstpctl-bpduguard yes
mstpctl-portbpdufilter yes
vxlan-id 10
vxlan-local-tunnelip 4.4.4.4
vxlan-remoteip 1.1.1.1

router bgp 65004
bgp router-id 4.4.4.4
coalesce-time 1100
neighbor swp4 interface remote-as external
address-family ipv4 unicast
network 4.4.4.4/32
neighbor swp4 soft-reconfiguration inbound
Topology works fine, but what I try to understand is how to track state of VXLAN tunnels?
I can see the VXLAN interface is up on leaf1:

cumulus@cumulus:~$ net show interface | egrep "Name|vni"
Name Master Speed MTU Mode Remote Host Remote Port Summary
UP vni-10 bridge N/A 1500 Access/L2

But if I shut down VXLAN interface on leaf2 I do not see anything that would indicate this on leaf1.
I understand that I can use for example EVPN where I can see remote endpoints for each VNI if they are accessible.
Is it possible for static VXLAN configuration to track the state of the tunnel?
Thank you!
