17-65 Cisco Prime Network 4.3.2 User Guide Chapter 17 Managing MPLS Networks Configuring MPLS-TP Step 2In the link properties window, right-click on the required physical link and choose the Show MPLS-TP tunnels option. The MPLS-TP tunnels’ commands dialog box is displayed, which lists all the tunnels in the selected link. Step 3In the MPLS-TP tunnels’ commands dialog box, choose the tunnels that you want to lock and select the Lock Out option in the Commands field. Step 4Click Execute Now. You are prompted to confirm the lockout operation. Step 5Click Ye s to confirm. A message is displayed confirming that the selected tunnels have been locked. The status of the tunnel is automatically updated as Lockout(UP) after this operation. Unlocking MPLS-TP Tunnels To unlock MPLS-TP tunnels in bulk: Step 1In the map view, right-click the required link and choose Properties. Step 2In the link properties window, right-click on the required physical link and choose the Show MPLS-TP tunnels option. The MPLS-TP tunnels’ commands dialog box is displayed, which lists all the tunnels in the selected link. Step 3In the MPLS-TP tunnels’ commands dialog box, select the locked tunnels that you want to unlock and select the Unlock option in the Commands field. Step 4Click Execute Now. You are prompted to confirm the unlock operation. Step 5Click Ye s to confirm. A message is displayed confirming that the selected tunnels have been unlocked. The status of the tunnels is automatically updated as Active(UP) after this operation. NoteIf you attempt to unlock a tunnel that is not locked, a message is displayed indicating that there are no valid tunnels to perform the unlock operation. Linear Protection for MPLS-TP As explained earlier, MPLS-TP is the transport profile that fulfills the deployment in the network for the MPLS technology. This technology provides fast protection switching for end-to-end segments wherein the protection switching time is generally less than 50 milliseconds. Protection switching is a mechanism wherein route and resources of a protection path are reserved for a selected working path or set of working paths. Linear protection provides rapid and simple protection switching because it can operate between any pair of points within the network. For every working Label Switched Paths (LSP) in the network, there is a protected LSP that is not related to any other working entity. When a working LSP fails, the protected LSP is ready to take up transmission of data. In Prime Network, the following commands are available for linear protection:
17-66 Cisco Prime Network 4.3.2 User Guide Chapter 17 Managing MPLS Networks Configuring MPLS-TP Force Switch (Lockout)—This command is used to switch normal traffic from a working LSP to a protected LSP. This command can only be applied on a working LSP. If Force Switch is enabled, then the Working LSP becomes standby and the Protected LSP becomes active. Manual Switch—This command is used to switch normal traffic from a working LSP to a protected LSP. This command can be applied only on a working LSP. If Manual Switch is enabled, then the working LSP becomes standby and the protected LSP becomes active. NoteThe Force Switch and Manual Switch commands are both used to switch traffic from the working LSP to the protected LSP. However, if the Manual Switch command is used, and there is a failure in the protecting LSP, then the working LSP becomes active. In case of the Force Switch command, then the working LSP does not become active if there is a failure in the protecting LSP.+ Lockout of Protecting (Lockout)—This command is used to switch traffic from the protected LSP to the working LSP. This command can be applied only on a protected LSP. If Lockout of Protecting is enabled, then the working LSP becomes active and the protected LSP becomes standby. Clear Force Switch (no Lockout)—This command is used to clear the force switch on a working LSP after which the working LSP becomes active and the protected LSP becomes standby. Clear Manual Switch—This command is used to clear the manual switch made on a working LSP, after which the working LSP becomes active and the protected LSP becomes standby. Clear Lockout of Protecting (no Lockout)—This command is used to clear the lockout of protecting made on a protected LSP. The working LSP becomes standby and the protected LSP becomes active after this command is executed. Figure 17-24 depicts the MPLS-TP topology along with the working and protected LSPs: Figure 17-24 Linear Protection for MPLS-TP NoteIn the above figure, you can find working and protected LSPs between two routers. In case of maintenance or network upgrade, the Force Switch and Manual Switch commands can be used to shut down the working LSP link. Similarly, the Lockout of Protecting command can be used to shut down the protected LSP link. To switch traffic using the Force Switch or Manual Switch command:

Viewing MPLS LDP, Static Information The Multi-Protocol Label Switching (MPLS) is a scalable, protocol-independent transport. In an MPLS network, data packets are assigned labels. The packet-forwarding decisions are made solely based on the contents of this label, without the need of examining the packet itself. This enables creating end-to-end circuits across any type of transport medium using any protocol. Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) enables peer label switch routers (LSRs) in an MPLS network to exchange label binding information for supporting hop-by-hop forwarding in an MPLS network.Command Navigation Description Create VRRP Group Delete VRRP InterfaceRouting Entities > Routing Entity > IP Interfaces tab, right-click the required interface> Commands > ConfigurationConfigure a group of routers to form a single virtual router. Example is using VRRP group as default router on the client.
