I am very new to CISCO, I have 2 networks A & B
A is on 172.16.1.0/24, router is on 172.16.1.2
B is on 172.16.4.0/24, router is on 172.16.4.1
in Network B, there is also had internal network 192.168.210.0
currently, from network A (172.16.1.0/24) I able to connect to 172.16.4.0/24 but how to connect network 192.168.210.0 ?
