3 method configuring default route on hub spoke network GNS3 ip default-network ip route ip default-gateway this example we�ll use RIP, you can also use EIGRP but not OSPF prepare the network R1 interface FastEthernet0/0 ip address 10.1.1.1 255.255.255.0 duplex auto speed auto ! interface Serial0/0 ip address 192.168.1.1 255.255.255.0 clock rate 64000 ! interface Serial0/1 ip address 172.16.1.1 255.255.255.0 clock rate 64000 ! router rip network 172.16.0.0 network 192.168.1.0 R2 interface Serial0/0 ip address 192.168.1.2 255.255.255.0 ! router rip network 172.16.0.0 network 192.168.1.0 R3 interface Serial0/0 ip address 172.16.1.2 255.255.255.0 ! router rip network 172.16.0.0 make sure R1, R2 and R3 learn all the advertised interfaces and RIP working fine by pinging from one to other interfaces R1>sh ip rou R 99.0.0.0/8 [120/1] via 192.168.1.2, 00:00:16, Serial0/0 172.16.0.0/24 is subnetted, 1 subnets C 172...
