Features
Cisco 12000 series routers feature a high-performance switched backplane providing 2.4 Gbit/s across 16 switched ports simultaneously.{{cite web |title=Fast Switched Backplane for a Gigabit Switched Router |publisher=Department of Electrical Engineering, Stanford University |url=http://idc-online.com/technical_references/pdfs/data_communications/Fast_Switched_backplane_for_gigabit_switched_router.pdf |accessdate=January 19, 2013}}
The Multi-Service Blade module (introduced for the XR 12000 line) provides firewall and acts as a session border controller.{{cite web |last=Duffy |first=Jim |date=March 19, 2007 |title=Cisco adds firewall, SBC module to XR 12000 line |publisher=Network World |url=http://www.networkworld.com/news/2007/031907-cisco-firewall-xr12000.html |accessdate=January 19, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20081203163148/http://www.networkworld.com/news/2007/031907-cisco-firewall-xr12000.html |archive-date=December 3, 2008}}
Criticism
Certain line cards in Cisco 12000 routers are potentially vulnerable to denial-of-service attacks.{{cite web |last=Leyden |first=John |date=15 November 2001 |title=Cisco high-end routers in DoS peril |publisher=The Register |url=https://www.theregister.co.uk/2001/11/15/cisco_highend_routers_in_dos/ |accessdate=January 19, 2013}} Additionally, certain software versions were vulnerable to specially crafted IPv4 packets.{{cite web |last=Berndtson |first=Chad |date=May 27, 2011 |title=Cisco Warns Of Vulnerabilities In IOS XR Software |publisher=CRN |url=http://www.crn.com/news/security/229700102/cisco-warns-of-vulnerabilities-in-ios-xr-software.htm |accessdate=January 19, 2013}}
