MPLS

MPLS Overview:

Multi-Protocol Label Switching (MPLS) defines a mechanism for packet forwarding in network routers. It was originally developed to provide faster packet forwarding than traditional IP routing, although improvements in router hardware have reduced the importance of speed in packet fowarding. However, the flexibility of MPLS has led to it becoming the default way for modern networks to achieve Quality of Service (QoS), next generation VPN services, and optical signaling.

Traditional IP networks are connectionless: when a packet is received, the router determines the next hop using the destination IP address on the packet alongside information from its own forwarding table. The router's forwarding tables contain information on the network topology. They use an IP routing protocol, such as OSPF, IS-IS, BGP, RIP or static configuration, to keep their information synchronized with changes in the network.

MPLS also uses IP addresses, either v4 or v6, to identify end points and intermediate switches and routers. This makes MPLS networks IP-compatible and easily integrated with traditional IP networks. However, unlike traditional IP, MPLS flows are connection-oriented and packets are routed along pre-configured Label Switched Paths (LSPs).

How does MPLS work?

MPLS works by tagging packets with an identifier (a label) to distinguish the LSPs. When a packet is received, the router uses this label (and sometimes also the link over which it was received) to identify the LSP. It then looks up the LSP in its own forwarding table to determine the best link over which to forward the packet, and the label to use on this next hop.
A different label is used for each hop, and it is chosen by the router or switch performing the forwarding operation. This allows the use of very fast and simple forwarding engines, as the router can select the label to minimize processing.

Ingress routers at the edge of the MPLS network use the packet's destination address 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.

In the diagram above, 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.

As MPLS uses only the label to forward packets, it is protocol-independent, hence the term "Multi-Protocol" in MPLS. Packet forwarding has been defined for all types of layer-2 link technologies, with a different label encoding used in each case.

MPLS Protocols

MPLS defines only the forwarding mechanism; it uses other protocols to establish the LSPs. Two separate protocols are needed to perform this task: a routing protocol and a signaling protocol.

MPLS Routing Protocols:

The routing protocol distributes network topology information through the network so that the LSP can be calculated. An interior gateway protocol, such as OSPF or IS-IS, is normally used, as MPLS networks typically cover a single administrative domain.

However, these routing protocols only distribute network topology. When traffic engineering is required to establish LSPs with guaranteed QoS characteristics and backup LSPs that avoid any single point of failure, the traffic engineering (TE) extensions to these protocols are used. These extensions distribute QoS and Shared Risk Link Groups (SRLGs) information on each link in the network. This information enables the route calculator to determine routes through the network with guaranteed QoS parameters, and backup LSPs that traverse different links from the primary path.

Mechanisms to extend this traffic engineering to inter-area and inter-carrier routing are still being agreed. Our White Paper on "Inter-Area Routing, Path Selection and Traffic Engineering" provides a detailed discussion of this topic.

MPLS Signaling Protocols

The signaling protocol informs the switches along the route which labels and links to use for each LSP. This information is used to program the switching fabric. One of two main signaling protocols is used, depending on the network requirements.

• RSVP-TE is used where traffic engineering is required. LDP is used when traffic engineering is not required, as it needs less management.
  

BGP is also used as a combined routing and MPLS signaling protocol in some situations. An example of this is BGP/MPLS VPNs.

Advanced MPLS Applications:

Optical MPLS

The concept of a label has been extended in Generalized MPLS (GMPLS). In GMPLS, the label no longer needs to be carried as an identifier on the data flow, but may be implicit. For example, time-slots (in SONET/SDH) and wavelengths (in DWDM) can be labels. In these cases, the label switching operations translate to operations such as "switch this incoming wavelength onto this outgoing wavelength."

GMPLS is therefore ideal for optical networking, and many extensions to the protocols have been defined, including user-to-network interfaces and network-to-network interfaces.

MPLS in Hierarchical Networks

MPLS is ideal for hierarchical networks, where lower-layer switching entities (for example packets) are aggregated into a higher-layer entity, for example a time-slot, and then once again into a wavelength and a whole fiber. MPLS allows a label stack to be defined so that switches can switch higher-layer aggregations and ignore the lower levels of the label stack. When the flow arrives at a switch capable of handling lower-layer entities, the switch strips off the outer label and examines the next lower level in the stack.

One example of the use of label stacking is in BGP/MPLS VPNs, where a two-deep label stack is used.

A transport label is used to route aggregated VPN traffic to the destination edge router in the provider's network. This is conventional MPLS, using either RSVP-TE or LDP signaling.

Once at the destination edge router, the transport label is stripped off and the second label examined. This label identifies the specific VPN to which the flow belongs. These VPN labels are signaled in extensions to the BGP protocol.

Cisco Router Password Recovery Procedure

Step-by-Step Procedure:

-----------------------------------
Attach a terminal or PC with terminal emulation to the console port of the router. Use the following terminal settings:
9600 baud rate No parity 8 data bits 1 stop bit No flow control
Type show version and record the setting of the configuration register. Click here to see output of a show version command.
The configuration register setting is usually 0x2102 or 0x102.
Using the switch, turn off the router and then turn it on.
Press Break on the terminal keyboard within 60 seconds of the powerup to put the router into ROMMON.
If the break sequence doesn't work, try CTRL+BREAK or use the terminal program to send the break as an ascii code.
Type o/r 0x2142 at the > prompt to boot from Flash without loading the configuration.
Type i at the > prompt.
The router reboots but ignores its saved configuration.
Type no after each setup question or press Ctrl-C to skip the initial setup procedure.
Type enable at the Router> prompt.
You'll be in enable mode and see the Router# prompt.
Important Type config mem or copy start running to copy the nonvolatile RAM (NVRAM) into memory. Do not type config term.
Type wr term or show running.
The show running and wr term commands show the configuration of the router. In this configuration you see under all the interfaces the shutdown command, which means all interfaces are currently shutdown. Also, you can see the passwords either in encrypted or unencrypted format.
Type config term and make the changes.
The prompt is now hostname(config)#.
Type enable secret .
Issue the no shutdown command on every interface that is used. If you issue a show ip interface brief command, every interface that you want to use should be "up up".
Type config-register 0x2102, or the value you recorded in step 2.
Press Ctrl-z to leave the configuration mode.
The prompt is now hostname#.
Type write mem or copy running startup to commit the changes.

Explanation, Fault Identification and Correction

Step1: Simulation understanding

Identify the faults in configuration on RTR_1 and RTR_2.

As the SIM specifies all other inter connectivity and internet access for the existing locations of the company are working properly.

Routing Protocols used in the SIM is EIGRP with AS 212 as provided by exhibit.

Faults Identified:

1. Wrong AS (EIGRP 22) provided at RTR_2 (New router),
2. RTR_1 does not advertise the new network between RTR_1 and RTR_2 into EIGRP.

We need to correct the above two configuration mistakes to have full connectivity

Correction:

Step2:

Correcting the EIGRP AS to 212 & Advertise the routes

Wrong AS (EIGRP 22) provided at RTR_2 (New router). All routers that want to exchange routes within EIGRP needs to be in same Autonomous System.

First we need to remove the current wrong EIGRP AS 22 from Router RTR_2

Click on Host-F to get CLI of RTR_2

RTR_2(config-router)#end

Note: Necessary step, save the changes made to router RTR_2

RTR_2#copy run start

Step 3:

RTR_1 does not advertise the new network between RTR_1 and RTR_2 into EIGRP.

Click on Host-G to get CLI of RTR_1

The network 192.168.77.0 is used between RTR_1 Fa0/0 - RTR_2 Fa 0/0.

This network needs to be advertise into EIGRP routing process at RTR_1

RTR_1>enable

Password : cisco (Provided in simulation)

RTR_1#conf t

RTR_1(conf)#

Enter EIGRP routing process for AS 212

RTR_1(conf)#router eigrp 212

The network 192.168.77.0 is used between RTR_1 Fa0/0 - RTR_2 Fa 0/0 .

Advertise this network into EIGRP

RTR_1(config-router)#network 192.168.77.0

RTR_1(config-router)#end

Important save the changes made to router

RTR_1RTR_1#copy run start

From RTR_2 CLI ping RTR_1 Serial 1/0 IP address 198.0.18.6

RTR_2#ping 198.0.18.6

!!!!!

A successful ping shows the new RTR_2 will have full connectivity with other routers.
