Answer question
Rnrp configuration for primary network(172.16.4.x),secondary network(172.16.12.x)
I know RNRP will work for primary network 172.16.x.x,secondary network 172.17.x.x.
But I have to do for 172.16.4.x and 172.16.12.x.
Will Rnrp work for same network with different area?
Is there any configuration required in PC to make Rnrp work?
