HOWTO: OpenWrt Static Routes Questions

OpenWrt version: Official 22.03.0-rc1
Device: mi-router-cr6608 (Level 2 router)
Topology:Level 1 router, Level 2 router A:, router B:
Subject: communication between 2 Level 2 routers
Configuration on Level 2 router B:

But it seems to be no effects,cannot find these in STATUS->ROUTING:
in SSH, cannot find these in command route:

root@OpenWrt:~# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default UG 0 0 0 wan * U 0 0 0 br-lan * U 0 0 0 wan

I can add static routes by command route, but it cannot persist during reboot, I want to know how to do it in Luci?

You need to add a unicast not an anycast route.

I've tried to use lan/wan interface with unicast/anycast but with no luck...
