In this article, we will connect two Routers, Cisco and MikroTik, through the Ip Tunnel, a protocol used to provide network access for two devices that are not physically connected. For this you will need a static IP and a local IP address in both locations, 10.200.0.1 and 172.16.16.2 will be the “public” IP addresses, as shown in the example below.

On the Cisco router, in the general configuration mode, we enter the following configuration to create the IP tunnel:

Backing up and restoring Cisco Router / Switches often saves us from a great mess in our network systems that have collapsed. Now, let’s briefly back up our cisco devices, and then let’s do the barber how to restore this backup.

In the first step, we will see how the backup process is done.

Cisco Router / Switch BACKUP

1. Open TFTP server

2. Access Cisco Router/Switch

3. Try to ping the TFTP server

Administrative Distance (AD)

Before starting RIP we should about Administrative Distance (AD).
AD: Sets the priority of routing protocols. If 2 protocols are configured on a router, the router will first put the data of the low AD protocol in the routing table.
The table below contains the administrative distance values of the routing protocols. The data of the protocol with a low AD value is placed first in the routing table.

DEFAULT ROUTİNG

Default routing is used to send packets to the next-hop router for an unknown remote destination network that is not in the routing table. Default routing should only be used in stub networks, which are the only way out of the network.

As you can see in the above picture, while R1 and R3 can be used defective routing. Because R2 is not effective to use the default routing.
Router(config) #ip route 0.0.0.0 0.0.0.0 10.0.0.1
The above command means to send all unknown packets to output 10.0.0.1, wherever they come from.

IP ROUTING

Routers know how to reach the networks they are connected to. However, they do not know how to reach remote networks that not connected. But, they can learn how to access remote networks to which they are not connected by using one of the following routing protocols.
1. Static routing
2. Default routing
3. Dynamic routing
a) RIP (international standard)
1) RIPv1       2) RIPv2
b) IGRP (cisco-based protocol, but not supported by cisco anymore)
c) EIGRP (cisco-based)
d) OSPF (international standard)
e) Is-Is  (international standard)
