The Performance Route Processor (PRP) is the core of a GSR.

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]

IP Services Engine (ISE) with four Gigabit Ethernet SFPs on the left.

Features

Cisco 12000 series routers feature a high-performance switched backplane providing 2.4Gbit/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]

Criticism

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]
