When changing anything on a VxLAN interface, the FRR config is removed back to a default config.
### Before change:
```
vyos@PE2# run show ip ospf nei
Neighbor ID Pri State Up Time Dead Time Address Interface RXmtL RqstL DBsmL
10.1.2.1 1 Full/- 3.746s 33.700s 10.1.2.1 eth1:10.1.2.2 1 0 0
```
```
vyos@PE2# sudo vtysh -c "show run"
Building configuration...
Current configuration:
!
frr version 10.2.2
frr defaults traditional
hostname PE2
service integrated-vtysh-config
!
ip route 0.0.0.0/0 10.0.101.1 eth0.101 tag 210 210
ip route 0.0.0.0/0 10.0.101.1 245

exit
```
### After Change:
```
vyos@PE2# set interfaces vxlan vxlan0 parameters neighbor-suppress
[edit]
vyos@PE2# commit
```
```
vyos@PE2# run show ip ospf nei
% OSPF is not enabled in vrf default
```
```
vyos@PE2# sudo vtysh -c "show run"
Building configuration...
Current configuration:
!
frr version 10.2.2
frr defaults traditional
hostname PE2
service integrated-vtysh-config
```
NOTE: This happens with any change to the VxLAN interface, not just parameters
### Restoring Config:
The config can be restored by making any change to BGP (likely other sections that would generate an FRR config as well):
```
vyos@PE2# set protocols bgp address-family l2vpn-evpn vni 100
vyos@PE2# commit
```
```
vyos@PE2# run show ip ospf nei
Neighbor ID Pri State Up Time Dead Time Address Interface RXmtL RqstL DBsmL
10.1.2.1 1 Full/- 8m40s 39.826s 10.1.2.1 eth1:10.1.2.2 0 0 0
```
### Log:
This is from right after changing something on the VxLAN interface:
