The Cisco perimeter router must be configured to not redistribute static routes to an alternate gateway service provider into BGP or an Interior Gateway Protocol (IGP) peering with the NIPRNet or to other autonomous systems. An XCCDF Rule
The Cisco perimeter router must be configured to not redistribute static routes to an alternate gateway service provider into BGP or an Interior Gateway Protocol (IGP) peering with the NIPRNet or to other autonomous systems.
Low Severity
<VulnDiscussion>If the static routes to the alternate gateway are being redistributed into an Exterior Gateway Protocol or Interior Gateway Protocol to a NIPRNet gateway, this could make traffic on NIPRNet flow to that particular router and not to the Internet Access Point routers. This could not only wreak havoc with traffic flows on NIPRNet, but it could overwhelm the connection from the router to the NIPRNet gateway(s) and also cause traffic destined for outside of NIPRNet to bypass the defenses of the Internet Access Points.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
