A method of linking inner and outer MPLS labels to provide enhanced security is disclosed. The method of linking inner and outer MPLS labels to provide enhanced security includes provisioning both an outer label database with reference keys. The outer label database entry provides a key that must be used in conjunction with the inner label database lookup to realize appropriate actions. As the provided key is not publically accessible an additional increment of security is provided. The method of linking inner and outer MPLS labels to provide enhance security is particularly useful blocking malicious packets from being sent into a remote VLAN or VFI. |
