configure mpls between linux host and mikrotik

*** setup information

linux ip : 192.168.56.24
       router-id: 1.1.1.2

mikrotik: 192.168.56.6
       router-id: 1.1.1.1


*** on linux
1- install quagga-ldpd and prerequisite
$ sudo apt-get install gcc
$ sudo  apt-get install libtool make autoconf gawk libreadline-dev texinfo
if your kernel is <4.2, upgrade your kernel
$ sudo install linux-headers-4.2.0-18 linux-headers-4.2.0-18-generic linux-image-4.2.0-18-generic

$ git clone https://github.com/rwestphal/quagga-ldpd.git
$ cd quagga-ldpd
$ autoreconf -i
$ ./configure --enable-mpls --enable-ldpd --sysconfdir=/etc/quagga --localstatedir=/var/run/quagga
$ make
$ sudo make install

2- create user and directory
$ sudo useradd -m quagga
$ sudo mkdir /var/run/quagga
$ sudo chown quagga:quagga /var/run/quagga

3- create the following configuration
- /etc/quagga/zebra.conf
hostname Router
password zebra
enable password zebra
/etc/quagga/ospfd.conf
 
-log file /var/log/quagga/ospfd.log
router ospf
 network 1.1.1.2/32 area 0.0.0.0
 network 192.168.56.0/24 area 0.0.0.0
!

- /etc/quagga/ldpd.conf
debug mpls ldp messages recv
debug mpls ldp messages sent
debug mpls ldp zebra
log file /var/log/quagga/ldpd.log
!
mpls ldp
 router-id 1.1.1.2
 !
 address-family ipv4
  discovery transport-address 1.1.1.2
  label local advertise explicit-null
  !
  interface eth0
  !
 !

4- setup the host to enable mpls routering
$ sudo sysctl -w net.ipv4.ip_forward=1
$ sudo modprobe mpls-router
$ sudo python -c "import os;os.system("echo 100000 > /proc/sys/net/mpls/platform_labels")
$ sudo python -c "import os;os.system("echo 0 > /proc/sys/net/mpls/conf/eth1/input")
$ sudo ip link add name lo1 type dummy
$ ifconfig lo1 1.1.1.2/32 up

5- run the folllow daemon
$ sudo zebra -d
$ sudo ospfd -d
$ sudo ldpd -d
