How long is the routing table update time? And xbee's routing table update policy?

How long is the routing table update time? And routing table update scheme?

I want to know your routing table management policy…
My xbee configuration is as below.
There were C-R1-R. I read the routing information of R1. It was okay.

Then I added R2 between C and R1. R2 was nearby R1.
I tried to read the routing table of R1.
But the routing table of R1 didn’t show the C-R2-R1 path…
I thought that your routing table would show the C-R2-R1 path…
Let me know your routing table management policy of xbee…
Or update time of routing table…

A routing table is only updated if the current rout is broken.

And No, it would not be C - R1 - R2 -E unless the Router 1 was only in range of the Coordinator, router 2 was only in range of both the end device and router 1.
