1.4 Configuration Procedure

1) Specify an LSR ID

From the system view, specify the MPLS LSR ID.

2) Run the MPLS

From the system view, run the MPLS.

3) Run the MPLS L2VPN

From the system view, run the MPLS L2VPN.

4) Create a CCC local connection

Create a CCC local connection, whose interfaces are the ports connected to RTC and RTD respectively.



1.5 Result Verification

1) Execute the display ccc command. You can find that a CCC local connection has been established.

[RTA]display ccctotal connections : 1local connections : 1, 1 upremote connections : 0, 0 up

name: CEA-CEB, type: local, state: up,intf1: Serial2/0 (up), intf2: Serial3/0:0 (up)

Note:

Local connection is a connection established between two local CEs. Switching can be completed directly on the PE, and no static LSP needs to be configured.

2) Detect the connectivity between RTC and RTD through the Ping command.[RTD] ping 172.1.1.2 PING 172.1.1.2: 56 data bytes, press CTRL_C to break Reply from 172.1.1.2: bytes=56 Sequence=1 ttl=255 time=31 ms Reply from 172.1.1.2: bytes=56 Sequence=2 ttl=255 time=29 ms Reply from 172.1.1.2: bytes=56 Sequence=3 ttl=255 time=29 ms Reply from 172.1.1.2: bytes=56 Sequence=4 ttl=255 time=30 ms Reply from 172.1.1.2: bytes=56 Sequence=5 ttl=255 time=30 ms

1.6 FAQ

Q: What’s the full name of CCC? Can a CCC connection bear multi-service? Why?

A: CCC is abbreviated from Circuit Cross Connect, and MPLS L2VPN is implemented through static configuration. Unlike the MPLS L2VPN which uses two layers of label, CCC uses one layer of label to transmit user data. Therefore, CCC uses the LSP exclusively.

Chapter 2 Configuration Guide to CCC Remote Connection


Figure 1-3

RTB and RTC are connected through Serial interfaces, and PPP is encapsulated at the link layer. RTA and RTB are connected through Ethernet interfaces, and so are RTC and RTD. RTA and RTD have a CCC remote connection established between them.

RTB’s interface connected to RTA does not need to have an IP address configured.

In VRP5.10, each CCC remote connection does not need to have two static LSPs, but only need to have an inbound label and an outbound label configured. The inbound label is used exclusively by the CCC connection. This has the same effect as a configured static LSP.

Note:

If the egress interface is an Ethernet interface, you must specify the next-hop IP address.

2) Run the MPLS

Run the MPLS from the system view and run the MPLS at the corresponding port.

3) Create a static LSP

Create two static LSPs from the MPLS view. Each LSP is responsible for unidirectional data transmission. To be specific, one LSP transmits data from RTB to RTD, and the other LSP transmits data from RTD to RTB.



5) Create a CCC remote connection

Create a CCC local connection, whose interfaces are the ports connected to RTC and RTD respectively.




Instructions for the author: Give the methods and procedures for verifying the result. Perform the verification in diversified ways on a step-by-step basis. In this way, the students can understand the working principles of services more completely while verifying the result.

1) Execute the display ccc command. You may find that a CCC remote connection has been established.

[RTB]display ccc total connections : 1local connections : 0, 0 upremote connections : 1, 1 up

Note:

If you view the CCC connection information on RTB and RTC, you will see an established CCC remote connection in UP status.

2) On the other hand, you may view the status information of the LSP and static LSP through the display mpls lsp and display mpls static-lsp commands.

2) Run the MPLS




3) Run the MPLS LDP

Run the MPLS LDP from the system view and activate the MPLS LDP at the corresponding port.

4) Create an LDP remote session

First, in the MPLS-LDP view, execute the remote-peer index command to enter the MPLS-LDP-Remote view.

Then, in the MPLS-LDP-Remote view, execute the remote-ip ip-address command to specify a remote peer entity.

Caution:

The precondition for establishing an LDP session is that a TCP connection must be established between the LSR-IDs of both parties. If both the routers take their Loopback addresses as LSR-IDs, each router needs the information of the route to the Loopback address of the other router.



6) Create a Martini MPLS L2VPN connection

Create an L2VPN connection at the access interface.


1) Execute the display mpls l2vc command to view the L2VPN connection information on RTB and RTC. You may find that an L2 VC is established.

3.6 FAQ

Q: What are the main contents of a Virtual Circuit (VC) that is established between two CEs in the Martini mode?

A: Martini uses VC-TYPE and VC-ID to identify a VC.

VC-TYPE: To indicate that the VC type is ATM, VLAN, PPP or others. VC-ID: VC-ID is unique in the whole PE for all VCs of the same VC-TYPE.

A PE that connects two CEs switches VC labels through LDP and binds CEs through VC-ID.

When an LSP is successfully established to connect two PEs, a VC is established after the two PEs complete label switching and binding. In this case, CEs at both ends may transmit layer-2 data over this VC.

In order to switch VC labels between PEs, the Martini draft expands the LDP by adding an FEC type: VC FEC.

In addition, it is possible that two PEs that switch VC labels are not connected directly, so the LDP must establish a remote session using remote peer and transmit VC FEC and VC label over the session.

3.7 Additional Task

Change the Martini access mode to PPP, and make RTA and RTD to be pinged successfully.

4.6 FAQ

Q: Why is Kompella applied extensively in practice?

A: Because the Kompella MPLS L2VPN also uses VPN Target to manage VPN routes. As a result, this networking mode is much flexible.

Q: Why should you assign a reasonable CE-ID range in configuring Kompella.

A: Because the CE range can only be made larger, but not smaller. To make a CE range smaller, you should first delete the CE and then re-create it.
