<Please login to see the content>
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
  • 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

Was going for the task SoO.
However when verifying for the double entry for e.g. on R6 only loopback10 exists. For some reason the route for 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 is installed via both interfaces.
On R6 I only see that 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
