For communication between two different networks, we configure the routing protocol. But basic configuration is required in all routers.
Basic Configuration
For Router 1
Router>enable
Router#configure terminal
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 192.168.0.1 255.255.255.192
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface Serial0/0/0
Router(config-if)#ip address 192.168.0.97 255.255.255.192
Router(config-if)#clock rate 64000
Router(config-if)#no shutdown
Router(config-if)#^Z
Router#wr
For Router 2
Router>enable
Router#configure terminal
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 192.168.0.65 255.255.255.224
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface Serial0/1/0
Router(config-if)#ip address 192.168.0.98 255.255.255.252
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface Serial0/0/0
Router(config-if)#ip address 192.168.0.101 255.255.255.252
Router(config-if)#clock rate 64000
Router(config-if)#no shutdown
Router(config-if)#^Z
Router#wr
For Router 3
Router>enable
Router#configure terminal
Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 192.168.0.105 255.255.255.252
Router(config-if)#no shutdown
Router(config-if)#exit
Router(config)#interface Serial0/1/0
Router(config-if)#ip address 192.168.0.102 255.255.255.252
Router(config-if)#no shutdown
Router(config-if)#^Z
Router#wr
Redistribution Configuration
we are doing redistribution of RIP and EIGRP, so on one router we have to configure RIP and on third router we have to configure EIGRP or visa versa and on the middle router or the router which have both others routers route that is middle router, we have to configure one interface in RIP and other interface in EIGRP. After that we configure redistribution.

Router 1 has rip route and router 3 has eigrp route, router 2 have both rip and eigrp route after configure interface of router 2 in respective protocol.
After configuration of redistribution, apply verification command in router 3.
