CCIE SPv4 - MPLS L3 VPN - VRF Lite - EIGRP and EIGRPv6

Software versions:
IOS XE 15.5
IOS XR 5.3

The topology for this demo:

This post will cover EIGRP in a VRF Lite environment. Like OSPF, EIGRP has full support for VRF Lite for both AFIs. I use named mode which is the only way IPv6 EIGRP is supported in our version of IOS.

Since we are running AFI aware EIGRP with named mode in IOS and specific to VRF Lite, we have the ability to get specific with our verification.
