Working group will examine security issues to determine what security threats it is appropriate for the VRRP protocol to handle and include the appropriate mechanisms in the VRRP protocol. The working group will also consider other internet drafts related to this topic allowing for issues regarding change control, security, running code, etc. Intellectual property issues regarding the technology to develop a virtual router redundancy protocol will be identified and addressed. Cisco claims VRRP infringes on the HSRP patent. Since HSRP was submitted to the working group, to standardize VRRP instead of HSRP would be an attempt to compromise patent rights.
