PE-CE Connectivity: EIGRP
The last protocol to review in this chapter is EIGRP. This protocol, described in depth in the EIGRP Network Design Solutions book by Cisco Press (ISBN 1-57870-165-1), has been widely adopted within the Enterprise space, and a large percentage of Enterprise networks rely on EIGRP for their connectivity requirements. Therefore, it is important to provide support for EIGRP within the MPLS VPN architecture, specifically for PE-CE connectivity.
EIGRP PE-CE Connectivity Requirements
As with all other PE-CE routing protocols, the MPLS VPN backbone within an EIGRP environment must be transparent. The backbone should also integrate with existing EIGRP route selection rules to ensure that the intersite traffic flow is affected ...
