This simulation is EIGRP Named. I have IPv4 and IPv6 configured for EIGRP using Address family. I have MD5 and SHA 256 setup for iosv2 and iosv4. I can ping out to the real world and TFTP IPv6 redirects.
In this diagram we have two VRF groups HR and ACCT. I used VRF to isolate HR department traffic from ACCT department traffic.
I setup loopbacks on each router that are in HR or ACCT. All routers can ping out to the real world. 172.16.1.1 is my 60E. 192.168.1.240 is my workstation for TFTP. I use redirects to build these pages. I used ip tftp source-interface g0/x to allow the TFTP traffic out.
EIGRP doesn’t allow default-information originate always. I setup ip route vrf routing commands for 0.0.0.0 0.0.0.0 as one test to get to the 60E and my workstation. A setup a second ip route vrf HR and ACCT with 172.16.1.0 255.255.255.0 and another set with 192.168.1.0 255.255.255.0 to get out. Either would work but for completeness, I did both.
