CTYPE html> OSPF and Networking Configuration

OSPF Configuration on the Router

Configure OSPF with Process ID 10

router ospf 10
router-id x.x.x.x

Replace x.x.x.x with the desired router ID (typically an IP address that uniquely identifies the router within the OSPF domain).

Advertise Networks

Advertise the g0/0/0 network (assuming 172.16.0.x/24):

network 172.16.0.0 0.0.0.255 area 0
network 192.168.x0.0 0.0.0.255 area 0

Advertise subinterfaces on g0/0/1 (VLAN subnets):

network 192.168.x1.0 0.0.0.255 area 0
network 192.168.x2.0 0.0.0.255 area 0
network 192.168.x3.0 0.0.0.255 area 0
network 192.168.x4.0 0.0.0.255 area 0

Replace x1, x2, x3, and x4 with the correct IP ranges for your subinterfaces.

Check OSPF

Check OSPF Neighbor Relationships:
```
show ip ospf neighbor
```
Check OSPF Routing Table:
```
show ip route ospf
```
Check OSPF Status:
```
show ip ospf
```
Check OSPF Database:
```
show ip ospf database
```

Student Router Configuration

Student	Router-ID	WAN	LAN 1	LAN 2	LAN 3	LAN 4
Eric	1.1.1.1	172.16.1.1	192.168.11.1	192.168.12.1	192.168.13.1	192.168.14.1

Set Up Remote Access to the Router

Configure SSH:

ip domain name renegar.lol
crypto key generate rsa general-keys modulus 2048
ip ssh version 2
line vty 0 4
login local

Create User Accounts:

username eric privilege 15 secret P@ssword
username cameron privilege 15 secret P@ssword
username adam privilege 15 secret P@ssword

Test Access:

ssh -l name 172.16.0.1
telnet 172.16.0.1
password: P@ssword

Configuring VLANs and Trunking

Steps:

Create VLANs
Assign Ports to VLANs
Set Up a Trunk Port
Verify Configuration

enable
conf t
vlan 10
 name LAN1
vlan 20
 name LAN2
vlan 30
 name LAN3
vlan 40
 name LAN4

interface range g1/0/1-5
 switchport mode access
 switchport access vlan 10

interface range g1/0/6-10
 switchport mode access
 switchport access vlan 20

interface range g1/0/11-15
 switchport mode access
 switchport access vlan 30

interface range g1/0/16-20

interface g1/0/24
 switchport mode trunk
 switchport trunk allowed vlan 10,20,30,40

Configuring DHCP Pools and Sub-interfaces

DHCP Pools:

ip dhcp pool LAN1
