EIGRP Lab: Redistribution, Route-maps and Tagging

Overview:
========
 This lab is an extension fo the previous lab, EIGRP over frame-relay. In this lab I added R4 to the topology and configured the R4<>R1 link in EIGRP AS1. I also created loopbacks on R4 and advertised them into EIGRP AS2.
Objective:
=========
1. Redistribute EIGRP AS1 routes into EIGRP AS2 routes( Simple)
2. Use route map to redistribute loopback routes into EIGRP AS1 and tag the /24 or lesser subnets with 2000.
Config:
======

R4#             sh ip prefix-list det
Prefix-list with the last deletion/insertion: LOW
ip prefix-list LOW:
   count: 1, range entries: 1, sequences: 5 - 5, refcount: 3
   seq 5 permit 40.0.0.0/8 le 24 (hit count: 6, refcount: 1)
