From Wikipedia, the free encyclopedia
The Cisco 12000, also known as a Gigabit Switch Router or GSR, is a series of large network routers designed and manufactured by Cisco Systems.[1]
Cisco 12000 series routers feature a high-performance switched backplane providing 2.4 Gbit/s across 16 switched ports simultaneously.[2] The Multi-Service Blade module (introduced for the XR 12000 line) provides firewall and acts as a session border controller.[3]
Certain line cards in Cisco 12000 routers are potentially vulnerable to denial-of-service attacks.[4] Additionally, certain software versions were vulnerable to specially crafted IPv4 packets.[5]
