Want to know how to crash the Internet?
Cisco has issued an alert warning that a vulnerability in a commonly used routing protocol can be used to bring down service provider's core Internet infrastructure.
The vulnerability concerns BGP (Border Gateway Protocol), which is used for exchanging routing information between gateway host on the Internet, and can be exploited to create network outages.
Cisco said the issue came to light because of a malfunction in the BGP implementation of another (unnamed) vendor, which caused a series of crashes but it admits the problem might also affect its own kit.
