TASK 2: Configure OSPF area 0 on R2, R3, and R4 on the links connecting the routers to each

other and their L0 interface only.

R2 Configuration

router ospf 1

network 2.2.2.2 0.0.0.0 area 0

network 10.1.23.2 0.0.0.0 area 0

R3 Configuration

router ospf 1

R4 Configuration

router ospf 1

network 4.4.4.4 0.0.0.0 area 0

network 10.1.34.4 0.0.0.0 area 0



TASK3 Configure Label Distribution Protocol on Core Routers. Ensure that the LDP-ID is based

on the IP address assigned to the Loopback O interface of these router .

Configure Following label ranges on these routers

R2: 200 – 299

R3: 300 – 399

R4: 400- 499

On all Routers:

mpls label protocol ldp

mpls ldp router-id loopback0

R2 Configuration

int eth0/1

mpls ip

int eth0/1

mpls ip



mpls label range 200 299

Once done Reload to take this Effect.



TASK4: Configure MP-BGP between R2 – R4 as they are RE routers and in AS 65001.Dont allow

BGP peers to share IPV4 routing information by –default. BGP Peering relationship will be

VPNV4.
