Back in 2014, I wrote an article that highlighted that global Internet routing table passed the 512,000 or 512k route mark. Today we know that another significant milestone has been reached, as we passed the 768,000 or 768k route mark! Many have predicted Internet outages may be expected. In short, the “sky is not falling”. The possibility of TCAM resource exhaustion at 768k routes is a known issue that we all know has been coming for some time. There is no related security vulnerability, and it cannot be easily triggered by a remote, untrusted user.
