Hello Everyone.
I am trying to build a small network and based on my skills i tried setting up 2 routers, but seems like they can not ping each others G0/0/1. Below is my configurations.
RB:
show run | begin interface interface GigabitEthernet0/0/0 ip address 10.128.250.215 255.255.255.0 ip nat outside negotiation auto ! interface GigabitEthernet0/0/1 ip address 172.16.0.1 255.255.255.0 ip nat inside negotiation auto ! interface Serial0/1/0 ip address 172.16.1.1 255.255.255.0 ! interface Serial0/1/1 no ip address shutdown ! interface GigabitEthernet0 vrf forwarding Mgmt-intf no ip address shutdown negotiation auto ! --More-- ip forward-protocol nd ip http server ip http authentication local ip http secure-server ip tftp source-interface GigabitEthernet0 ip nat inside source list 1 interface GigabitEthernet0/0/0 overload ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 ! ! ! ip access-list standard 1 10 permit 172.16.0.0 0.0.255.255 ! ! ! !
RC:
show run | begin interface interface GigabitEthernet0/0/0 ip address 10.128.250.214 255.255.255.0 ip nat outside negotiation auto ! interface GigabitEthernet0/0/1 ip address 172.16.0.2 255.255.255.0 ip nat inside negotiation auto ! interface Serial0/1/0 ip address 172.16.1.2 255.255.255.0 ! interface Serial0/1/1 no ip address shutdown ! interface GigabitEthernet0 vrf forwarding Mgmt-intf no ip address shutdown negotiation auto ! --More-- ip forward-protocol nd ip http server ip http authentication local ip http secure-server ip tftp source-interface GigabitEthernet0 ip nat inside source list 2 interface GigabitEthernet0/0/0 overload ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 ! ! ! ip access-list standard 2 10 permit 172.16.0.0 0.0.255.255 ! ! !

You can't use the same subnet on each router (172.16.0.x) and expect it to work because each router thinks that subnet is local to it so it will never send the ping across the link.
Change one of the routers gi0/0/1 interface to use a different subnet eg 172.16.1.x and then try your ping.
