Routes Lab 01 - HQ LAN Routing Configuration

HQ LAN will use OSPF area 1. Once the configuration is done, other branch routers should be able to reach HQ LAN.

Below are couple of useful command to check on connectivity.

ping
traceroute
show ip route
show ip route ospf
show ip route a.b.c.d

Routes Lab 01 - HQ LAN address config

sooo.. before we proceed to make HQ LAN available over the WAN to other branch, make sure you have below config ready. There'll be a couple of changes from the original plan, I've decided to use Vlan interface rather than Loopback for Core01/02. After all config applied, make sure all point to point are ping-able.

because vlan config is not shows up in the runnning config, so I have to show you the actual config that I put in

all ping-able and looks good ? later we start to advertise HQ LAN over the WAN

Routes Lab 01 - WAN OSPF area 0

We could use a few type of frame-relay network (NBMA or point-to-multipoint). Let's go with point-to-multipoint, it's like a collection of point-to-point network from each sites. This is not going to be a Hub and Spokes network because each site have it's own DLCI to others. So it's a full mesh network.

Add below command on all WAN interfaces to make a point-to-multipoint Frame-relay network.

interface Serial0/1

 ip ospf network point-to-multipoint

configure OSPF area 0 for the WAN interfaces and Loopbacks, do the same for the rest of the Net

router ospf 1

 log-adjacency-changes

 network 10.9.9.1 0.0.0.0 area 0

 network 70.0.0.1 0.0.0.0 area 0

make sure neighbor are formed between the three WAN routers. below are a few useful command to get some information and troubleshoot.

show ip route

show ip route ospf

sh ip ospf interface serial 0/1

show ip protocols

show ip ospf

show ip ospf neighbor

next we will configure routing on the LAN using EIGRP and redistribute it to the OSPF so that the other side of the network can reach it.

Routes Lab 01 - Basic Frame-Relay

set the DLCI for NetA Frame-Relay switch as below

configure the Routers IP as below, make sure they can ping to each other IP address.

hq-rtra#

interface Serial0/1

 ip address 70.0.0.1 255.255.255.0

 encapsulation frame-relay

 clock rate 2000000

 frame-relay map ip 70.0.0.2 102 broadcast

 frame-relay map ip 70.0.0.3 103 broadcast

 no frame-relay inverse-arp

End

moon-rtra#

interface Serial0/1

 ip address 70.0.0.2 255.255.255.0

 encapsulation frame-relay

 clock rate 2000000

 frame-relay map ip 70.0.0.1 201 broadcast

 frame-relay map ip 70.0.0.3 203 broadcast

 no frame-relay inverse-arp

End

mars-rtra#

interface Serial0/1

 ip address 70.0.0.3 255.255.255.0

 encapsulation frame-relay

 clock rate 2000000

 frame-relay map ip 70.0.0.1 301 broadcast

 frame-relay map ip 70.0.0.2 302 broadcast

 no frame-relay inverse-arp

end

do the same for the NetB or backup WAN.. once finish test all the connectivity. Next we will start to configure the OSPF for the Frame-Relay

Routes Lab 01

let's start a route lab, I don't really have a specific topic to focus on, but basically we will go thru three main topics related to OSPF, EIGRP and Redistribution (or maybe some others thing that might seems to be a good idea to be included along the way)

In this scenario, we have a HQ and two branch office. All three sites connected via 2 ISP (WAN), NetA for primary and NetB for backup. HQ and Moon sites have their own Internet gateway.

prepare your GNS topology as below diagram with (1) DLCI (2) GNS3 (3) IP scheme details

*please take note that I missed Loopback 0 for all the WAN routers.
rtra hq/moon/mars - 10.9.9.1/2/3 255.255.255.255
rtrb hq/moon/mars - 10.9.9.11/12/13 255.255.255.255

next lab we will start with Frame-relay configuration.
*please take note that first half of the upcoming labs will focus on Primary WAN which is NetA network, we will bring up the backup WAN later..
