Back in the Game - I have a session tonight

[Tom4498]

It has been a long time since I had a session on www.expert-labs.com. I have a session tonight where I want to get a basic setup in place and work out the bugs.

I haven't had much time to prepare and I think some of the gear has changed since the last time. I am hoping to go over Frame-Relay and some OSPF and BGP. If I have time, I would like to plan with NAT and GRE tunnels.

The basic layout is below.

loopbacks - 172.16.1.0/32
Serial Links - 172.31.1.x/30
Frame Relay - 192.168.1.0/24
VLAN10 - 10.1.10.0/24
VLAN20 - 10.1.20.0/24

Here is the basic config for each device. It should bring up a loopback, ethernet and a very basic frame-relay config. I will hammer out something more substantial in the next section for frame-relay.

I decided to build a very basic OSPF network. I am going to have to rework my unlying IP scheme to get more flexibility out of the network.

10.1.10.0/24 - OSPF Area 0
10.1.20.0/24 - OSPF Area 1
192.168.1.0/24 - OSPF Area 2
172.31.1.0/24 - OSPF Area 3
172.31.1.4/24 - OSPF Area 4
172.31.1.8/24 - OSPF Area 5
172.31.1.0/24 - OSPF Area 6

I setup a simple OSPF setup, but it was boring and didn't have alot of areas. I went back and broke up frame-relay into one network with three multipoint devices and two point to point links. I also went back and broke out each ethernet into its own segment. This leads to some more interesting scenarios. I don't think I am going to have time to do this....

R1 + R2 + R3 = OSPF network
R5 = transit area to R4 and R6 + BGP
R4 = Ripv2 + BGP
R6 = Ripv2 + BGP
