Technology application MPLS In the network and use routing protocols to experiment with the network and learn about MPLS

1. Ping Show ip route

2. MPLS VPN Configure all IP addresses as specified in the topology picture. Configure a loopback0 interface on each router: HQ: 1.1.1.1 /25 SP1: 2.2.2.2 /25 SP2: 3.3.3.3 /25 SP3: 4.4.4.4 /25 BRANCH: 5.5.5.5 /25 Configure OSPF Area 0 at the provider side (Router SP1, SP2 and SP3). Advertise the loopback interfaces as well in OSPF. Ensure you have full reachability in the OSPF domain. Configure MPLS on all physical interfaces in the service provider domain, do not configure MPLS on physical interfaces pointing towards the customer. Force MPLS to use the loopback interface as router-id.

3. Configure VRF “customer” on SP1 and SP3 as following: RD 100:1 Route-target both 1:100 On router SP1 and SP3 add the interfaces pointing towards the customer to the VRF you just created. Ensure you can ping from within the VRF, try this as following on SP1: ping vrf customer 192.168.12.1 Configure EIGRP AS 100 on router HQ and Branch. Advertise the loopbacks as well. Disable EIGRP auto-summary . Configure EIGRP on router SP1 and SP3 for the correct VRF “customer”. Ensure you have established a EIGRP neighbor relationship between Router HQ and SP1, and between SP3 and Branch. See if you have learned routes by using “show ip route vrf customer”.
