Features
Cisco 12000 series routers feature a high-performance switched backplane providing 2.4Gbit/s across 16 switched ports simultaneously. The Multi-Service Blade module (introduced for the XR 12000 line) provides firewall and acts as a session border controller.
Criticism
Certain line cards in Cisco 12000 routers are potentially vulnerable to denial-of-service attacks. Additionally, certain software versions were vulnerable to specially crafted IPv4 packets.
