MPLS VPN

Multi-Protocol Label Switching (MPLS) :

Provides a mechanism for forwarding packets for any network protocol.

Unlike traditional IP, MPLS flows are connection-oriented and packets are routed along pre-configured Label Switched Paths (LSPs).

MPLS directs and carries data from one network node to the next

MPLS is operable between the Data Link Layer and the Network Layer.

MPLS VPN: (P2P VPN)

Virtual Private Network (VPN) :

A Data network that utilizes a portion of a shared public network to extend a customer’s private network.

VPN use cryptographic tunnelling protocols to provide high level security;

Important for anyorganizations that havemanyoffices at different locations. Why?

To expandtheirnetworkingcapabilities

To securetheirtraffic

To reducetheircost

Layer 2 MPLS VPN

How Does it Work?

MPLS-basedLayer 2 VPNsprepends a label to a Layer 2 PDU and thenforwarding the packet across the MPLS backbone.

Provider (P) routers not be aware of the VPNs. They will continue to forward packets over pre-establishedlSPs.

CE Routers will operatewithoutanyknowledge of the existence of MPLS VPNs.

PE Routers do not participate in the routingalgorithms of the end-users, and there no requirements for the construction of VPN routing and forwardingtables (VRFs)

MPLS VPN

How Does it Work?

A different label is used for each hop, and it is chosen by the router or switch performing the forwarding operation.

Ingress routers at the edge of the MPLS network classify each packet potentially using a range of attributes, not just the packet's destination ddress, to determine which LSP to use.

Inside the network, the MPLS routers use only the LSP labels to forward the packet to the egress router. Contd…...

MPLS VPN

How Does it Work?

An LSP acts as a tunnel carrying multiple VCs

VCs are uni-directional, for bi-directionalcommunication, a pair of VCs – one in eachdirection –is needed.

Tunnel LSPsbetween the PE routers could be createdusinganyprotocol like RSVP/TE or LDP

PE routers exchange the VC labels via LDP

The PE router encapsulates the subscriber layer- 2 frame and attaches two labels ( top & inner)

The receiving PE router pops the tunnel label and use the inner label to deliver the packet to the correctend-user.

MPLS VPN

How Does it Work?

Customer frames are switched based on their destination MAC address.

VPN is established by creating a full mesh of VCs between the PEs facing the sites that make the VPN.

A PE router maintains a separate layer-2 forwarding table, VirtualForwardingInstance (VFI), for each VPN that it carries.

A PE router learns MAC addressesrelatedonly to the VPNs that it carries.

A P router does not learnany MAC addtreeses, they just performlabelswitching.

slide9

LSR (Label Switched Router) A uses the destination IP address on each packet to select the LSP which determines the next hop and initial label for each packet (21 and 17).

When LSR B receives the packets, it uses these labels to identify the LSPs, from which it determines the next hops (LSRs D and C) and labels (47 and 11).

The egress routers (LSRs D and C) strip off the final label and route the packet out of the network.
