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.
Part 2 of this video goes over the use of Site-of-Origin attribute
Topic:
- EIGRP Basic Configuration
- EIGRP metric in VPNv4 routes
- Site-of-Origin (SoO) – Dualed Home Site
- Site-of-Origin (SoO) – Site with Backdoor
- BGP Cost Community

On R6/7 no topology entries but for their own loopbacks!?
Hi,
Was going for the task SoO.
However when verifying for the double entry for e.g. on R6 6.6.0.0/24 only 0.0.0.0 loopback10 exists. For some reason the route for 6.6.0.0 through R7 is not even considered as en entry for the topology table.
I cleared R7 eigrp and ran a debug ip eigrp on R6 and R7.
On R7 a route for 6.6.0.0/24 is installed via both interfaces.
On R6 I only see that 6.6.0.0/24 is advertised towards R7.
I working with Cisco router IOSv from Virl in GNS3 with only Gi interfaces but I do not think that is the cause. Or is it?
Your thoughts ? :)
Thanx Jaap
