Cisco CCNP – BSCI Tutorial: The Role Of The OSPF ASBR

To pass the BSCI exam and earn your CCNP certification, you’ve got to master the (many) details of OSPF. You might have thought there were quite a few OSPF details in your CCNA studies, but you’ll now build on that foundation on the way to earning your CCNP.

One such detail is the role of the Autonomous System Border Router (ASBR) in OSPF. The name itself raises some eyebrows, since you learned in your CCNA studies that OSPF doesn’t use autonomous systems! Just as an OSPF Area Border Router borders multiple OSPF areas, the ASBR borders the entire OSPF domain and another source of routes. This can be another dynamic routing protocol, or directly connected networks that are not being advertised into OSPF by the network command.

Cisco CCNA – CCNP Certification Exam Lab: Frame Relay Subinterfaces And Split Horizon

Earning your Cisco CCNA and CCNP is a tough proposition, and part of that is the fact that you quickly learn that there’s usually more than one way to do things with Cisco routers – and while that’s generally a good thing, you better know the ins and outs of all options when it comes to test day and working on production networks. Working with Frame Relay subinterfaces and split horizon is just one such situation.

Cisco CCNA Exam Tutorial: Using Trivial File Transfer Protocol (TFTP)

One of the first things you do when you start studying for the CCNA exam is memorizing a list of port numbers and the protocols that run on those ports. If you’re an experienced networker, you know most of the protocols that are mentioned – DNS, DHCP, FTP, SMTP, and so on. But there’s one protocol that you might not have experience with, but is actually vital for CCNA exam success and success in working with Cisco routers and switches, and that’s TFTP – Trivial File Transfer Protocol.

TFTP is basically FTP’s non-secure relative. There are no passwords, no authentication scheme, no nothing! As someone once told me, “If I’m transferring my files, there’s nothing ‘trivial’ about it.”

Cabling your home for computer network – still a requirement?
