Quickstart with LDP daemon

Step 1: Boot an MPLS enabled kernel - see MPLS
Step 2: Run /usr/sbin/ldpd
Step 3: Add some routes to neighbors bindings and see routes being automatically tagged or just use zebra/quagga in order to do avoid manual routes
Step 4: You can look over some reports on control interface: telnet localhost 2626 - use root password - and use question mark for help

/etc/ldpd.conf example

# a default ldpd.conf
   
#       hello-time 8;
        max-label 400;
        min-label 200;
        command-port 2424;
#       ldp-id 1.2.3.4;


# USE TCP SIGNATURE FOR THIS NEIGHBOUR - don't forget to add entries in ipsec.conf && echo ipsec=yes >> /etc/rc.conf
# add -4 1.2.3.4 1.2.3.50 tcp 0x1000 -A tcp-md5 "mypassword" ;
# add -4 1.2.3.50 1.2.3.4 tcp 0x1000 -A tcp-md5 "mypassword" ;

        neighbour 1.2.3.50 {
                authenticate yes;
        }
