What's Hot

Cisco "TAC Certified" Graphic Tags To Be Removed From Document Hypertext Links

The Cisco "TAC Certified" Program was launched in November 1999 to help TAC Web site users quickly locate the most recent, edited, and/or lab-checked Cisco TAC Web site technical support documentation developed by Cisco TAC engineers. Since November, Cisco TAC engineers have published hundreds of "TAC Certified" technical support documents on the Cisco TAC Web site, and there is no longer a need to place a "TAC Certified" graphics tag next to each of these documents. TAC Certification will continue on the Cisco TAC Web site as a mark of high-quality technical support content, but effective immediately all "TAC Certified" material will be denoted only with a "TAC Certified" reference within the actual document.

Tech Tip:
Removing Private Autonomous System Numbers in BGP

When customers are multihomed to a single Internet Service Provider (ISP), the ISPs assign private autonomous system (AS) numbers in order to conserve AS numbers. When Border Gateway Protocol (BGP) a nnounces customer prefixes to external neighbors, it needs to drop the private AS number from the path.
