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…

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

IOS upgrade on Cisco Switch in Stack

Upgrading Cisco switch in stack :
The .bin file is the Cisco IOS Software image. If you want to use only the CLI to manage the switch, this is the only file you need to download. To upgrade follow this steps: 1. Download the bin image from the cisco.com website. 2. Issue the dir flash: command to verify the amount of free memory that you have for the upgrade. 3. Copy the bin image to the flash of each switch. In this case, two are the switches so the commands are: copy ftp: flash1: copy ftp: flash2: 4. Configure the boot variable to boot the switch with the newly copied IOS: boot system switch all flash:/c2960s-universalk9-mz.150-2.SE5.bin

5. enter "reload" command from Master Switch. All stack members will be reloaded.

Note: if you just issue the reload command from the master, the whole stack will reboot. The reload slot [id] will reload a single switch.
