Commiting exchange of tunnel remote ip does not resolve dependencys (fail)

Bugs
1

Hello,

when my ansible playbook writes a new configuration with order changes in tunnel naming vyos cant apply them properly because It does not resolve the dependencies/arrangement correctly.

As you can see, it attempts to exchange the remote IP of two tunnels simultaneously, which VYOS cannot handle. the problem is that it does not take into account that you cant have 2x tunnel interfaces with same remote and source combination at the same time, even for quick time. for types gre/gretap…


vyos@vyos# comp
[interfaces tunnel]
+ tun669001 {
+     encapsulation "gretap"
+     mtu "1462"
+     remote "66.66.66.1"
+     source-address "1.1.1.1"
+ }
+ tun669002 {
+     encapsulation "gretap"
+     mtu "1462"
+     remote "66.66.66.2"
+     source-address "1.1.1.1"
+ }

its a bit annoying. i can with some effort write some sort of workaround, but i think this isnt a solution. i think vyos should handle such cases, correct me if im wrong, but thats what this is all for, right?

i confirmed this issue in latest rolling Version: VyOS 2026.01.24-0021-rolling.

and also in 2025-Q2 Stream.

Thanks!
