MPLS - Basic MPLS Part 1
October 23rd, 2008 in CCIE SP | tags:

Recently I decided to start looking into CCIE SP. Since I already am a CCIE R&S, CCIE SP seems to be the logical next step. Below you can see a topology I created with GNS3. It is a simple MPLS network just to start things off.

MPLS

The config-file looks like this :

autostart = False
[localhost:7202]
    workingdir = C:\Temp
    udp = 10100

    [[3640]]
        image = C:\Program Files\Dynamips\images\c3640-js-mz.123-14.T3\C3640-JS.BIN
        idlepc = 0x604ed000
        ghostios = True
        chassis = 3640

    [[ROUTER R5]]
        model = 3640
        console = 2005
        slot0 = NM-1FE-TX
        f0/0 = R4 f3/0
        slot1 = NM-1FE-TX
        slot2 = NM-1FE-TX
        slot3 = NM-1FE-TX

        slot1 = NM-1FE-TX

You can grab the GNS3 file here

In the next part I will show how to configure MPLS, BGP and OSPF for this network.
