Multiprotocol Label Switching MPLS is a way of routing traffic within a telecommunications network that directs data from one node to the next based path labels rather than long network addresses, It also allows the sharing of address space for clients as it is labels that are being routed not prefixes. MPLS was designed to work in a multiple protocol environment. Hi Roger, Very nice and self explanatory tutorial.
Is it possible for you to write and explain further more. I am Oussema from Tunisia and I have found this tutorial very useful for me. Thanks for this post.
Would you mind send me the GNS3 config files for this lab please? I would be so grateful. These are the subnets of the links — each router is configured with an address from that subnet. Therefore, both should act in the same way, or am I wrong? I have updated the tutorial and it is now complete, please review the last steps again and let me know if you get any issues. The initial config lists setting it with a R3 hostname R3 int lo0 ip add 3. Im interested in the troubleshooting, where can I find this?
Thank you BTW the tutorial was great, a lot to take in, but I loved that you went from start to finish. The following show ip route vrf commands show the same prefix Skip to content Skip to search Skip to footer. Available Languages.
Download Options. Updated: September 9, Contents Introduction. The logical units of the core interfaces are configured to belong to both family inet and family mpls.
The logical unit of the customer edge interface is configured to belong to family ccc. The logical unit of the core interface is configured to belong to both family inet and family mpls. Aggregated Ethernet interface on PE-2 that connects to aggregated Ethernet interface ae0 of the provider switch and belongs to family mpls. Table 3 shows the MPLS configuration components used for the provider switch in this example.
The statement must specify the loopback and the core interfaces that will be used for the RSVP session. The logical units for the loopback interface and the core interfaces belong to family inet.
The logical units of the core interfaces are also configured to belong to family mpls. To quickly configure the local ingress PE switch, copy the following commands and paste them into the switch terminal window of PE Configure family mpls on the logical unit of the core interface addresses:. To quickly configure the remote PE switch, copy the following commands and paste them into the switch terminal window of PE Configure family mpls on the logical unit of the core interface:.
To quickly configure the provider switch, copy the following commands and paste them into the switch terminal window:. Verify that the interfaces are up.
Perform this verification task on each of the switches. The show interfaces terse command displays status information about the Gigabit Ethernet interfaces on the switch. This output verifies that the interfaces are up. The Local column for the core interfaces shows the IP address configured for these interfaces. Verify the state of the configured routing protocol. The state must be Full. The show ospf neighbor command displays the status of the routing protocol. This output shows that the state is Full , meaning that the routing protocol is operating correctly—that is, hello packets are being exchanged between directly connected neighbors.
The show mpls interface command displays the status of the core interfaces that have been configured to belong to family mpls. This output shows that the interface configured to belong to family mpls is Up. Verify the status of the RSVP sessions.
Verify which interface is being used as the beginning of the CCC and which interface is being used to push the MPLS packet to the next hop. Perform this task only on the PE switches. After you have checked the local PE switch, run the same command on the remote PE switch. The show connections command displays the status of the CCC connections.
