Hello.
Site A - usg 1100 v4.72
Site B - usg flex 50W v5.32

Hi @alexey
Could you share your network topology with IP address for us? It is convenient for us to realize your situation. Thanks.See how you've made an impact in Zyxel Community this year!

Hi @alexey
Please share your policy route setting with us as well. We would like to check the next hop setting. If you could share both devices' configs with us by private that would be better. Thanks.See how you've made an impact in Zyxel Community this year!

Hi @alexey
Additionally, if the next-hop is chosen as a tunnel and the outgoing interface is the doll interface while you execute the trace route action. Let you know that. Thanks.See how you've made an impact in Zyxel Community this year!

Firstly, problem site was connected via ipsec tunnel with dynamic peer. All work fine.
After configure 2 vti interfaces in trunk, policy route was change to new next hop via new trunk.
Site began unavailable on both sides.
Traffic goes to doll interface.
After reboot USG1100 with no changes in confuration file all start work as expected. Mysticly!
So i see this reproducing steps:
1 USG Flex 50 connect via USB modem by ipsec with dynamic peer for long time with connect/disconnect.
2 Disable ipsec tunnel, create 2 vti interfaces beetween devices and union they in trunk.
3 Change policy route to new trunk.
4 Nothing work0 -

Thanks for your response, we would like to clarify your reproducing steps:
"So i see this reproducing steps:

2 Disable ipsec tunnel, create 2 vti interfaces beetween devices and union they in trunk.

4 Nothing work"
So, the 5th step is to reboot USG1100 and USG Flex 50 and then the policy routes(the next hop with VTI trunk) are working suddenly?
Thanks.See how you've made an impact in Zyxel Community this year!
