Cisco CCNP - BSCI Tutorial: To Pass the BSCI exam And Earn Your CCNP Certification,



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.

Let's say we have a router running both OSPF and RIP version 2. By default, the RIP process will not contain any OSPF-discovered routes, and vice versa. The two separate routing processes are just that - separate. If we want the other OSPF routers to know about the RIP routes, route redistribution must be configured. When the RIP routes are redistributed into OSPF, that router is then an ASBR.

In the below example, RIP subnets have been redistributed into OSPF. A seed metric is not necessary when redistributing routes into OSPF. The command "show ip ospf" confirms that this router is now an ASBR.

R1(config)#router ospf 1

R1(config-router)#redistribute rip subnets

R1#show ip ospf

Routing Process "ospf 1" with ID 1.1.1.1

Supports only single TOS(TOS0) routes

Supports opaque LSA

It is an autonomous system boundary router

The ASBR can also perform route summarization on the routes being injected into OSPF with the summary-address command. (To configure OSPF inter-area summarization, use the area range command.) By mastering route summarization and route redistribution, you're well on your way to passing the BSCI exam and earning your CCNP certification!

Microsoft Unveils Bing Search Engine



Microsoft Corporation’s brand new search engine Bing, codenamed kumo in it’s early development stage, has started to roll out last June 3 to deliver “new search experience” to it’s users and address what it’s describes as the “unmet needs” of other search engine users.


Microsoft executives believe that Bing, organizes information in a more logical fashion: “Instead of splitting them out (search results) in order of popularity, we break them into logical categories. We bring the best match to the top, pull out results buried on the site, highlight information, highlight instant answers and show related searches right on the result page, “ they said.

Bing claims to provide credibility as well, especially when users search for areas in health and or diseases. Being claims to pull in information first from the top medical sources in the world. Microsoft hopes for its new search engine to be eventually accepted as a verb following the Google example.
