Removing interface l2tpeth0 from bridge br1

Hi @plastilin
What version? Please, describe steps on how to reproduce it.

Hello. 1.2.5 version.

I create bridge br1, add into bridge eth1, create l2tpv3 with bridge-group option br1 + commit + save after i remove l2tpv3 interface and result you see.

Hello @plastilin, it should be fixed in 1.2.6. This is just wrong output as I remember
