Lab 8-1B OSPF PT Activity
Configuring OSPF in Packet Tracer:
In this individual lab, you will configure OSPF for a small enterprise with 4 routers.
Use the following table for IP addressing of your devices and networks. X is the number of your birthdate.
| Network Name | Network Address | Subnet Mask | Default Gateway | Router acting as Gateway |
|---|---|---|---|---|
| Border-to-Data Center | 10.22.1.0 | 255.255.255.248/29 | 10.22.1.1 | Border |
| East-Router2 to Data Center | 10.22.1.20 | 255.255.255.252/30 | 10.22.1.21 | East-Router |
| DataCenter-to WestRouter4 | 10.22.1.32 | 255.255.255.252/30 | 10.22.1.33 | Data Center-Router |
| East | 10.22.20.0 | 255.255.255.0/24 | 10.22.20.1 | East-Router |
| West | 10.22.40.0 | 255.255.255.0/24 | 10.22.40.1 | West-Router |
Table for PC IP addresses
| East-PC | 10.22.20.6 |
|---|---|
| West-PC | 10.22.40.6 |
Add your name as part of the hostname on each router (e.g. hostname Adam-EastRouter2)
- This is required to demonstrate it is your own PT file in the screenshots
Use IP info above to configure the network (this means assigning IP addresses to the appropriate router interfaces)
NOTE/Tips: The router-to-router subnets only have two addresses (/30) - the "router acting as gateway" gets the first useable address - and the other router on that network gets the next (only other) useable address.
Don't forget to set port status as on!
Assign ip to the East and West PC's from the appropriate network
(At this point, all routers can ping each other and the PCs can ping the routers in the same network)
Configure OSPF on all the routers:
Goal is to have East PC Ping West PC
Create an OSPF instance: The process ID specific to that router
#(config) router ospf instance_number (usually just 1)
Add all of the Directly Connected Networks on that router
- Network address with wildcard mask and area #
#(config-router) network (IP Address) (Inverse Mask=the last has to be the remainder of 255) area 0
