Introduction

The goal of this tutorial is to experiment with authentication and SDU protection policies. The scenario to be setup is illustrated in the figure below.

Tutorial 3 scenario

Configuration

Configuration files must be copied to the stack's installation path "etc" folder (e.g. if you installed it in /usr/local/irati, config files must be in /usr/local/irati/etc).

Customer border router

Copy the following files into <installation_path>/etc. The configuration assumes that this system will communicate via the Ethernet interface "eth1", configured with VLAN "300".

Provider border router 1

Copy the following files into <installation_path>/etc. The configuration assumes that this system will communicate via the Ethernet interface "eth1", configured with VLAN "300" and via the Ethernet interface "eth2", configured with VLAN 310.

Provider border router 2

Copy the following files into <installation_path>/etc. The configuration assumes that this system will communicate via the Ethernet interface "eth1", configured with VLAN "310".

System initialization

Customer border router

Configure the VLAN 300 on the eth1 interface

modprobe 8021q
ip link add link eth1 name eth1.300 type vlan id 300
ip link set dev eth1 up
ip link set dev eth1.300 up

Load the RINA kernel modules

modprobe shim-eth-vlan
modprobe rina-default-plugin
modprobe normal-ipcp

Startup the IPC Manager in the background

cd <installation_path>/bin
./ipcm -c ../etc/ipcm.conf -l DEBUG &

Log into the IPCM console

telnet localhost 32766

If everything went ok, you should see the following output when typing the "list-ipcps" command

IPCM >>> list-ipcps
Current IPC processes (id | name | type | state | Registered applications | Port-ids of flows provided)
    1 | test-eth-vlan:1:: | shim-eth-vlan | ASSIGNED TO DIF 300 | A.IRATI-1-- | -
    2 | A.IRATI:1:: | normal-ipc | ASSIGNED TO DIF access.DIF | E.IRATI-1-- | -
    3 | E.IRATI:1:: | normal-ipc | ASSIGNED TO DIF multi-provider.DIF | - | -

Provider 1 border router

Configure the VLAN 300 on the eth1 interface and VLAN 310 on the eth2 interface

modprobe 8021q
ip link add link eth1 name eth1.300 type vlan id 300
ip link set dev eth1 up
ip link set dev eth1.300 up
ip link add link eth2 name eth2.310 type vlan id 310
ip link set dev eth2 up
ip link set dev eth2.310 up

Load the RINA kernel modules

modprobe shim-eth-vlan
modprobe rina-default-plugin
modprobe normal-ipcp

Startup the IPC Manager in the background

cd <installation_path>/bin
./ipcm -c ../etc/ipcm.conf -l DEBUG &

Log into the IPCM console

telnet localhost 32766

If everything went ok, you should see the following output when typing the "list-ipcps" command

IPCM >>> list-ipcps
Current IPC processes (id | name | type | state | Registered applications | Port-ids of flows provided)
    1 | test-eth-vlan:1:: | shim-eth-vlan | ASSIGNED TO DIF 300 | B.IRATI-1-- | -
    2 | test-eth-vlan2:1:: | shim-eth-vlan | ASSIGNED TO DIF 310 | C.IRATI-1-- | -
    3 | C.IRATI:1:: | normal-ipc | ASSIGNED TO DIF regional.DIF | F.IRATI-1-- | -
    4 | B.IRATI:1:: | normal-ipc | ASSIGNED TO DIF access.DIF | F.IRATI-1-- | -
    5 | F.IRATI:1:: | normal-ipc | ASSIGNED TO DIF multi-provider.DIF | - | -

Provider 2 border router

Configure the VLAN 310 on the eth1 interface

modprobe 8021q
ip link add link eth1 name eth1.310 type vlan id 310
ip link set dev eth1 up
ip link set dev eth1.310 up

Load the RINA kernel modules

modprobe shim-eth-vlan
modprobe rina-default-plugin
modprobe normal-ipcp

Startup the IPC Manager in the background

cd <installation_path>/bin
./ipcm -c ../etc/ipcm.conf -l DEBUG &

Log into the IPCM console

telnet localhost 32766

If everything went ok, you should see the following output when typing the "list-ipcps" command

IPCM >>> list-ipcps
Current IPC processes (id | name | type | state | Registered applications | Port-ids of flows provided)
    1 | test-eth-vlan:1:: | shim-eth-vlan | ASSIGNED TO DIF 310 | D.IRATI-1-- | -
    2 | D.IRATI:1:: | normal-ipc | ASSIGNED TO DIF regional.DIF | G.IRATI-1-- | -
    3 | G.IRATI:1:: | normal-ipc | ASSIGNED TO DIF multi-provider.DIF | - | -

Enrollment

From the provider border router 2, open the IPCM console and type the following commands

telnet localhost 32766
IPCM >>> enroll-to-dif 2 regional.DIF 310 C.IRATI 1
DIF enrollment successfully completed in 12 ms

IPCM >>> enroll-to-dif 3 multi-provider.DIF regional.DIF F.IRATI 1
DIF enrollment successfully completed in 16 ms

If everything went ok, you should see the "DIF enrollment successfully ..." statements. Now from the provider border router 1, open the IPCM console and type the following commands

telnet localhost 32766
IPCM >>> enroll-to-dif 4 access.DIF 300 A.IRATI 1
DIF enrollment successfully completed in 117 ms

IPCM >>> enroll-to-dif 5 multi-provider.DIF access.DIF E.IRATI 1 DIF enrollment successfully completed in 124 ms

As you have seen the enrollment takes much more time now, because both IPCPs have used the SSH2-based authentication policy, and encrypt all the traffic with the SDU Protection policy that uses AES128.

Trying some applications

rina-echo-time

Open a rina-echo-time server at the provider border router 2

cd <stack installation path>/bin
./rina-echo-time -l
18924(1445007262)#librina.logs (DBG): New log level: INFO
18924(1445007262)#librina.nl-manager (INFO): Netlink socket connected to local port 18924

If everything went ok, you should see the log statements. Now, at the customer border router open a rina-echo-time client, which will be sending 10.000 SDUs of 1400 bytes and maximum speeds, and compute some statistics from the replies.

cd <stack installation path>/bin
./rina-echo-time -w 0 -c 10000 -s 1400
4063(1445007376)#librina.logs (DBG): New log level: INFO

Minimum RTT: 0.3724 ms; Maximum RTT: 4.3496 ms; Average RTT:0.55281 ms; Standard deviation: 0.27377 ms

rina-tgen

Open a rina-tgen server at the customer router

cd <rina-tgen installation path>/bin
./rina-tgen -l
8839(1445007850)#librina.logs (DBG): New log level: INFO
8839(1445007850)#librina.nl-manager (INFO): Netlink socket connected to local port 8839

If everything went ok, you should see the log statements. Now, at the provider border router 2 open a rina-tgen client, which will be sending SDUs of 1400 bytes for 20 seconds at maximum speed (the speed that can be handled by the DIF).

cd <rina-tgen installation path>/bin
./rina-tgen --duration 20 -s 1400
25131(1445007877)#librina.logs (DBG): New log level: INFO
25131(1445007877)#librina.nl-manager (INFO): Netlink socket connected to local port 25131
