IP SLA tracking in Route MAP

Examples


The following configuration sample shows a configuration used to track an object:




! Configure the objects to be tracked.
! Object 123 will be up if the router can ping 10.1.1.1.
! Object 124 will be up if the router can ping 10.2.2.2.
ip sla monitor 1
 type echo protocol ipicmpecho 10.1.1.1
ip sla monitor schedule 1 start-time now life forever
!
ip sla monitor 2
 type echo protocol ipicmpecho 10.2.2.2
ip sla monitor schedule 2 start-time now life forever
!
track 123 rtr 1 reachability
track 124 rtr 2 reachability
!
! Enable policy routing using route-map alpha on Ethernet 0.
interface ethernet 0
 ip address 10.4.4.254 255.255.255.0
 ip policy route-map alpha
!
! 10.1.1.1 is via this interface
interface ethernet 1
 ip address 10.1.1.254 255.255.255.0
! 10.2.2.2 is via this interface
interface ethernet 2
 ip address 10.2.2.254 255.255.255.0
!
! Configure a route-map to set the next-hop to 10.1.1.1 if object 123 is up. If object 123
! is down, the next hop will be set to 10.2.2.2 if object 124 is up. If object 124 is also
! down, then policy routing fails and unicast routing will route the packet.
route-map alpha
 set ip next-hop verify-availability 10.1.1.1 10 track 123
 set ip next-hop verify-availability 10.2.2.2 20 track 124

SuperPuTTY for EVE-NG

To use SuperPuTTY as default client for telnet in Eve-NG for multi tab console

When we click on Router or Switch in EVE-NG by default console open in CMD. Here I posting a method to use SuperPutty with EVE-NG so that you can use TAB function of SuperPutty.
You need to edit registry 
Enable handling of telnet://hostname:port/ URLs on the command line. With this feature, you can now set SuperPuTTY as the default handler for Telnet URLs 
If you run the Registry Editor (Start->Run->regedit.exe) and set the value in:
HKEY_CLASSES_ROOT\telnet\shell\open\command to be: "\path\to\SuperPutty.exe"
(with the full pathname of your SuperPuTTY executable)

In my case it like this :

C:\Program Files (x86)\SuperPuTTY\SuperPutty.exe %1




Second most important thing :

Select "Only allow single instance of SuperPutty to run" in SuperPutty options (Tools > Options)




And in GUI options , select Tab Text : "Dynamic"




And Finally you will get the multi tab console in Superp…

Install Linux in Eve-NG

Install Linux in Eve-NG :
You can choose any of Linux image from the pack below and simply upload into EVE. Download your preferred image from this link:Download Linux Images Here  (This Link is Provided by EVE - NG)     2. Download your desirable image     3. Using WinSCP or FileZilla SSH (TCP 22) to your EVE and upload downloaded image to the location: /opt/unetlab/addons/qemu/     4. Using Putty or other telnet client, CLI SSH (TCP 22) to your EVE and go to location: cd /opt/unetlab/addons/qemu/    5. Unzip your uploaded image file, make sure you are using right name of uploaded image. Example for ubuntu desktop image below. tar xzvf linux-ubuntu-desktop-16.04.4.tar.gz    6. Remove raw zipped image file from EVE rm -f linux-ubuntu-desktop-16.04.4.tar.gz   7. Fix permissions /opt/unetlab/wrappers/unl_wrapper -a fixpermissions   6. Repeat this procedure for each downloaded image, expecting right image name in commands
Ready to go images recommeneded settings: IMPORTANT NOTE: Before you start Li…

NAT Cloud in EVE-NG

NAT Cloud in EVE-NG


I want to share with you how to create a NAT cloud in the EVE-NG community edition. Essentially, this is a virtual network with a DHCP server, which will allow NAT connections over the management interface of the EVE-NG VM for Internet access.


Interface, DHCP Server and NAT First of all, we need to create a network which can be used in the topology. I’ll be using the predefined pnet9 interface (Cloud 9 network) for this, but any other interface will do. 1 2 3 ip address add192.168.255.1/24dev pnet9 echo1

What is Ansible?

Ansible is a simple automation language or you can say application that can perfectly automate IT infrastructure or network infrastructure.

Ansible is a free-software platform for configuring and managing computers or network devices which combines multi-node software deployment, ad hoc task execution, and configuration management. (description taken from wikipedia)

It can also be used for network management. Like Puppet or Chef which requires agent to be installed on host system but Ansible does not require an agent on the host system. It uses SSH for transport to communicate with the host. When Ansible was first developed it was used primarily for server administration but in the last few years of development more and more network modules have been added to the software. Currently these Network vendor devices can be manage by Ansible. Current version is Ansible Ver 2.4 :

A10 Networks

Cisco ACI

Aireos

AOS

Aruba Networks

Cisco ASA

AVI

Bigswitch

Bigswitch

Citrix

Cloudengine

Cloudvision

Cumulus

Dell OS

First look of Open NX-OS

Cisco NX-OS is the network operating system that is used in Cisco Nexus switches. These Nexus switches from Cisco are built for DATA-CENTERS. In this post I will give you a brief idea regarding the NX-OS operating system.  NX-OS has been evolved from SAN-OS which was originally developed for MDS switches by Cisco only. These MDS switches are used for storage network.

Cisco NX-OS is purely based on Micro-kernel Linux where as traditional Cisco IOS is also based on Linux but with Monolithic kernel. I will tell you the difference between these two types of kernel below in this post because it is the key difference between NX-OS and IOS.
 Monolithic Kernel :
Monolithic kernel is a single large process running entirely in a single address space or memory space. It is a single static binary file. All kernel services exists and executes in the kernel address space. If one process having some problem then it will effect all other processes and may interrupt the complete kernel flow. As an ex…
