Hi, I have 2 tenants, each have a router, now I want to route tenant A traffic to tenant B, so I add static route in the tenant routers, then, everything work fine. The problem is the static route will be lost after restarting. How to save it permanently? Thanks

For example: 1. Add a route into a tenant router: ip netns exec qrouter-b65e4316-6dad-40af-b002-430b311aa239 ip route add 10.168.168.0/24 via 9.9.9.20

root@controller:/home/gavin# ip netns    exec    qrouter-b65e4316-6dad-40af-b002-430b311aa239 netstat -nr Kernel IP routing table  Destination     Gateway            Genmask         Flags   MSS Window   irtt Iface
   0.0.0.0         9.9.9.253       0.0.0.0         UG        0 0          0 qg-ea383fb8-36
   9.9.9.0         0.0.0.0         255.255.255.0   U         0 0          0 qg-ea383fb8-36    **10.168.168.0  
9.9.9.20        255.255.255.0   UG        0 0          0 qg-ea383fb8-36**
   192.168.169.0   0.0.0.0         255.255.255.0   U         0 0          0 qr-209078ed-73
