Basic Router Configuration, Static Routing Implementation
Working-Network Example
Configuring Router,switches and hosts
1. Router Configuration
Router>en
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip domain-lookup
Router(config)#interface gigabitEthernet 0/0
Router(config-if)#no shut down
Router(config-if)#exit
Router(config)#exit
Router#
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface gigabitEthernet 0/0.10
Router(config-subif)#encapsulation dot1Q 10
Router(config-subif)#ip address 10.1.1.1 255.255.255.0
Router(config-subif)#exit
Router(config)#interface gigabitEthernet 0/0.20
Router(config-subif)#encapsulation dot1Q 20
Router(config-subif)#ip address 20.1.1.1 255.255.255.0
Router(config-subif)#exit
Router(config)#interface gigabitEthernet 0/0.30
Router(config-subif)#encapsulation dot1Q 30
Router(config-subif)#ip address 30.1.1.1 255.255.255.0
Router(config-subif)#exit
Router(config)#do write
Router(config)#do show ip int brief
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 unassigned YES unset up up
GigabitEthernet0/0.10 10.1.1.1 YES manual up up
GigabitEthernet0/0.20 20.1.1.1 YES manual up up
GigabitEthernet0/0.30 30.1.1.1 YES manual up up
GigabitEthernet0/1 unassigned YES unset administratively down down
Vlan1 unassigned YES unset administratively down down
Router(config)#do show ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 10.1.1.0/24 is directly connected, GigabitEthernet0/0.10
L 10.1.1.1/32 is directly connected, GigabitEthernet0/0.10
20.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 20.1.1.0/24 is directly connected, GigabitEthernet0/0.20
L 20.1.1.1/32 is directly connected, GigabitEthernet0/0.20
30.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 30.1.1.0/24 is directly connected, GigabitEthernet0/0.30
L 30.1.1.1/32 is directly connected, GigabitEthernet0/0.30
Router(config)#end
2.Switches Configuration
i. Top switch (switch0)
Switch>
Switch>en
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#hostname VTP-Server
VTP-Server(config)#VTP mode server
Device mode already VTP SERVER.
VTP-Server(config)#vtp domain bct73
Changing VTP domain name from NULL to bct73
VTP-Server(config)#vlan 10
VTP-Server(config-vlan)#name admin
VTP-Server(config-vlan)#exit
VTP-Server(config)#vlan 20
VTP-Server(config-vlan)#name labs
VTP-Server(config-vlan)#exit
VTP-Server(config)#vlan 30
VTP-Server(config-vlan)#name students
VTP-Server(config-vlan)#exit
VTP-Server(config)#do show vlan
