The Juniper PE router must be configured with Unicast Reverse Path Forwarding (uRPF) loose mode, or a firewall filter, enabled on all CE-facing interfaces.
Medium Severity
<VulnDiscussion>The uRPF feature, and ingress firewall filters, are defenses against spoofing and denial-of-service (DoS) attacks by verifying if the source address of any ingress packet is reachable. To mitigate attacks that rely on forged source addresses, all provider edge routers must enable uRPF or ingress firewall filters to guarantee that all packets received from a CE router contain source addresses that are in the route table.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
