Processing a specially crafted IPv6 Type 0 Routing header can crash a device running Cisco IOS 
software. This vulnerability does not affect IPv6 Type 2 Routing header which is used in mobile 
IPv6. IPv6 is not enabled by default in Cisco IOS. 

Cisco has made free software available to address this vulnerability for affected customers. 

There are workarounds available to mitigate the effects of the vulnerability. The workaround 
depends on if Mobile IPv6 is used and what version on Cisco IOS is being currently used.
