The video extends the use of Route Target to implementing provider-managed CE devices in Cisco MPLS VPN. A provider usually only need a single IP on a managed CE device to be reachable and this is achieved by selectively exporting an IP, usually on a loopback interfaces, to the provider management VRF. This simple trick allows the provider to manage devices in multiple clients network without compromising network separation.

The video demonstrates different ways of using Route Target (RT) to build advance Cisco MPLS VPN topologies. We will spend time to gain a better understanding of the role of Route Target, and re-enforce the concept of Route Target import, and export, which is needed for our subsequent labs. These will be delivered through two example topologies of hub-and-spoke and extranet MPLS VPN. This method of exchanging routes between VRFs is also known as route leaking.

The video demonstrates configuration of BGP as PE-CE routing protocol in Cisco MPLS VPN. In addition to basic BGP configuration, we will go through more advance scenarios of dualed-home site and sites with a backdoor link, and try to understand how a Site-of-Origin (SoO) BGP attribute can be used to make inter-site traffic to always prefer the backdoor link. You will also learn two common BGP deployment options; identical and unique ASN, and the concept of AS Override. The lab finishes with verification of behavior of Local Preference in MPLS VPN.

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 demonstrates configuration of EIGRP as PE-CE routing protocol in Cisco MPLS VPN. In addition to basic EIGRP configuration, we will go through more advance scenarios of dualed-home site and sites with a backdoor link, and try to understand how a Site-of-Origin (SoO) BGP attribute can be used to prevent routes from being readvertised into its own site. The lab finishes with a discussion of BGP cost community, which is unique to EIGRP and the affect that it has on the path selection.
