PPP and host routes
Maybe some of you did configure a ppp connection and wondered about the new host route in the routing table after the PPP connection went alive. This is nothing to worry about since its a normal behavior of PPP and IPCP and also allows the routers to not even share the same subnet to get the line up and running.
Given the following diagram with a simple back to back connection between R4 and R5. Both interfaces have a different subnet.
About
Im a network engineer working for an international medical company based in Basel, Switzerland. I began my professional life in 2000 after 4 years of an IT apprenticeship. I started as the Network Management System responsible with quite a lot other of other tasks inside the Cisco networking field. In 2005 I changed to my current employer where I changed my field of knowledge from part NMS part Networking to full time Networking. I also started to educate myself deeper into networking. After passing the CCNA and CCNP exams I wanted to go further with my education and took the CCIE R&S track instead of doing a school with lots of stuff Im not interested in 
I started the CCIE journey in August 2007 with the first of 5 workshops at the Cisco Network Academy in Rapperswil and passed the CCIE in Brussels at 07th of May 2008.
During that time I wrote a lot of documents to keep the stuff I learned and I thought it might be an idea to make it public so it might help other people on their path through the Cisco Certifications. I hope this site gets useful not only for CCIE candidates but also for other networking professionals on their search for knowledge.
