It is possible for a single CE device to serve multiple MPLS clients. This requires traffic segregation to be extended to the CE device. The video looks at a scenario of multi-VRF CE device in Cisco MPLS VPN. We will configure two PE-CE routing protocols; BGP and OSPF, in VRF-lite setup and enable support for MPLS label exchange all the way to the CE router. Special configuration will be presented now that our CE router contains multiple VRF and participates in MPLS forwarding.

The video demonstrates configuration of OSPF as PE-CE routing protocol in Cisco MPLS VPN. In addition to basic OSPF configuration, we will go through more advance scenarios of dualed-home site and sites with a backdoor link, and try to understand how a use of Sham Link can prevent a backdoor link from being preferred over MPLS, and how Down-Bit and how Domain Tag can prevent learnt routes from being re-advertised out of the site. We will also look at the Domain ID and the affect that it has on OSPF LSA type.

The video walks you through basic and advance configuration of OSPFv3 on Cisco router. You will be able to see configuration similarities and differences between OSPFv3 and OSPF in IPv4. Our tasks include simple route advertisement, routing process and interface parameter adjustment, and route manipulation. We will also look at various types of OSPF area and LSA messages. You should become familiar with OSPFv3 by the end of this lab. We recommend having basic understanding of IPv6 before viewing this video.
