As of the version 4.0 blueprint OER/PfR is now being tested in the CCIE Routing & Switching lab exam. Since IOS release 12.4T Cisco renamed the technology previously called OER (Optimized Edge Routing) to PfR (Cisco Performance Routing). In the rest of this article and series the term PfR is used. The current command set is still using ‘oer’ but Cisco announced that this will become deprecated at some time.

Today we look an issue that often leads to some head scratching. For example, you redistribute OSPF into EIGRP and have reachability into the OSPF cloud.  Next, you redistribute a loopback into EIGRP and all of a sudden you can’t reach part of the OSPF network! Here is the topology:

R1—OSPF—R2—EIGRP—R3

OSPF: 192.168.12.0/24

EIGRP: 172.16.23.0/24

Hello everybody! Welcome to another tech-torial blog here at IPexpert!!!  Today we are going to be diving head first into one of the newest, most exciting, and in some ways most feared technologies on the new v4.0 R&S blueprint – MPLS L3 VPN.  Putting together this blog, I can see why Cisco has added this particular technology into the mix.  To get something like this working end to end you really HAVE to be an expert in many different technologies.  MPLS L3 VPN is not a single thing you have to master.  You must master all the little pieces individually, and then put it all together.  First, we’ll start with the quintessential network diagram of what we will be playing with today.
