MPLS P NODE REPLACEMENT USING LINK STATE PROTOCOL CONTROLLED ETHERNET NETWORK |
摘要 |
<p>When a MPLS Virtual Forwarding Entity (VFE) on a Link State Protocol Controlled Ethernet Network learns a forwarding equivalency class (FEC) to label binding from an attached MPLS-LER, it will determine an associated MAC address for the FEC, and advertise the FEC/label binding along with the MAC address. Nodes in the Ethernet network will install shortest path forwarding state for the MAC to the MPLS-VFE advertising the FEC/label binding. Each MPLS-VFEs on the Ethernet network that receive the advertisement will update its database and generate a label that is distributed to attached MPLS LERs using LDP. When the MPLS-LER needs to transmit traffic to the FEC, it will use the label provided by the MPLS-VFE. The MPLS-VFE maintains a mapping between the label and the MAC address so that it may use the MAC address to forward the packet across the Ethernet network.</p> |
