Alcatel

The Alcatel-Lucent virtualized Simulator (vSim) is a virtualization-ready version of SR OS called SR OS-VM. This new operating system is designed to run in a virtual machine (VM) on a generic Intel x86 server. In control and management plane aspects, the vSim is functionally and operationally equivalent to an Alcatel-Lucent hardware-based SR OS router.The vSim is intended to be used as a laboratory tool to fully simulate the control and management plane of an SR OS node. The vSim is not intended to be used in a production network environment and the forwarding plane is limited to 250 pps per interface. Furthermore, without a license file it will run for 1 hour before reloading.

Virtual Machines Software and Hardware Requirements

Extract image from the zip file.

$ unzip TiMOS-SR-13.0.R4-vm.zip

Now a virtual disk sros-vm.qcow2 is extracted. To start Qemu virtual machine use the command:

$ /usr/local/bin/qemu-system-x86_64 -m 2048MB -enable-kvm alcatel-sros-vm-13.0.R4.qcow2 -serial  telnet:localhost:3366,server,nowait -smp 2

Telnet to a serial port of virtual machine with the command:

$ telnet localhost 3366

Login with username admin and password admin.

Check  cards that are presented presented in a system with the command:

A:vRR# show card state

Picture 1 - Card iom3-xp-b is Detected but not Provisioned

Card IOM3-XP-B is equipped in slot 1 of chasis but it is not provisioned. Thus we mustto provision it for the slot 1.

*A:vRR# configure card 1 card-type "iom3-xp-b"

Picture 2 - Card iom3-xp-b Provisioned in Slot 1

Card iom3-xp-b accepts up to two Media Dependent Adapters (MDAs). There is a one unprovisioned module m5-1gb-sfp-b equipped in port one of card iom3-xp-b that provides five Ethernet interfaces.   We have to specify slot and mda type and save configuration.

*A:vRR# configure card 1 mda 1 mda-type "m5-1gb-sfp-b" *A:vRR# admin save

Now we can connect vSIM virtual machine to connect to GNS3.

We are going to create a simple topology in order to check network connectivity between vSIM ports and Core Linux hosts.

Picture 3 - Port Connectivity Testing Topology

They are six Linux Core hosts connected to the ports of virtual service router. A table mapping vSIM ports and how they are presented in TiMOS configuration is following:

Timos ----- vSIM ports bof ----------- eth0 1/1/1 --------- eth1 1/1/2 --------- eth2 1/1/3 --------- eth3 1/1/4 --------- eth4 1/1/5 --------- eth5

2.1 Configure GNS3 Qemu VMs Preferences

Navigate to Edit -> Preferences -> QEMU VMs and configure VM parameters according to the picture below.

Picture 4 - GNS3 Qemu VM Configuration

2.2 IP Address Configuration  for Control Proccessor Module (CPM) Management Ethernet Interface

The interface eth0 is connected to CPM management interface. Use BOF command-line interface (CLI) to configure IP address for CPM interface.

*A:vRR# bof address 10.10.10.1/24

Save bof configuration. *A:vRR# bof save

To ping an IP address of the host connected to a management interface of vSIM issue the command:

*A:vRR# ping 10.10.10.2 router "management"

The config file of vSIM router can be displayed with the command:

*A:vRR# admin display-config

2.15 Testing Connectivity between vSIM Ports

Login to PC1 and ping IP address of PC2, PC3, PC4 and PC5. As the hosts have default gateway configured, ping should be successful.

Picture 5 - Testing Connectivity Between vSIM Ports

In this lab we will focus on configuration and testing authentication in OSPF routing protocol running on Cisco CSR1000v router and Alcatel-Lucent virtual simulator.

Installation and configuration  of Cisco Cloud Service Router CSR1000v in GNS3 is explained here.

Picture 6 - OSPF Authentication Testing Topology

Note: A Link labeled as eth0 and connected to the first available port on CSR1000v is presented as interface GigabitEthernet 1 in CSR1000v configuration. Similarly, a link labeled as eth1 and connected to the second available port on Alcatel-Lucent vSIM is presented as port 1/1/1 in TiMOS CLI.

3.1 OSPF Configuration on CSR1000v

Password is set to lab123 and it must match between two OSPF neighbors.

Note: If you want to enable MD5 authentication for all interfaces in area 0, add the command:

CSR1000v-I(config-router)#area 0 authentication message-digest

3.2 OSPF Configuration Alcatel-Lucent Virtual Simulator

*A:vRR#configure system name Timos-I *A:Timos-I# configure port 1/1/1 no shutdown *A:Timos-I# configure router interface toCSR address 192.168.1.2/30 *A:Timos-I# configure router interface "toCSR" port 1/1/1 *A:Timos-I# configure router interface lo0 address 10.10.10.2/30 *A:Timos-I# configure router interface "lo0" loopback

*A:Timos-I# configure router ospf router-id 2.2.2.2 *A:Timos-I# configure router ospf area 0.0.0.0 interface "toCSR" interface-type point-to-point *A:Timos-I# configure router ospf area 0.0.0.0 interface "lo0"

Note: vSIM has the maximum transmission unit (MTU) set to 8936 Bytes for Ethernet interfaces by default. The default MTU value for CSR 1000v  Ethernet interfaces is 1500 Bytes. In order to establish OSPF neigborship between two routers, MTU must match on both sides of link. For this reason we must configure MTU 1500 Bytes for vSIM port 1/1/1.

However as it is shown from the debug command enabled on Cisco, CSR 1000v continues complaining about smaller size of MTU. The MTU received in OSPF packets from the neighbor vSIM router is 1486 Bytes. It causes that routers are not fully adjacent and they stay in EXCHANGE neighbor state.

CSR1000v-I#debug ip ospf adj *Dec 16 19:17:24.428: OSPF-1 ADJ Gi1: Rcv DBD from 2.2.2.2 seq 0x1E opt 0x42 flag 0x7 len 32 mtu 1486 state EXCHANGE *Dec 16 19:17:24.428: OSPF-1 ADJ Gi1: Nbr 2.2.2.2 has smaller interface MTU

Changing MTU parameter to 1514 Bytes for Ethernet port 1/1/1 on vSIM  helps to solve the issue.

*A:Timos-I# configure port 1/1/1 ethernet mtu 1514

3.3 OSPF MD5 Authentication Trobleshooting

We are going to check if routers are fully adjacent and if OSPF routes are presented in both routers's routing tables.
