BACKUP/RESTORE Cisco Devices:

Fast we are backup download on our TFTP server

Router#enable

Router#copy running-config tftp:

Address or name of remote host []? 8.8.8.8

Destination filename [Router-confg]? fast_backup


Writing running-config...!!

[OK - 963 bytes]

963 bytes copied in 0.035 secs (27514 bytes/sec)



 we want to upload this backup on our existing router :


Router#copy tftp: running-config

Address or name of remote host []? 8.8.8.8

Source filename []? fast_backup

Destination filename [running-config]?


Accessing tftp://8.8.8.8/fast_backup...

Loading fast_backup from 8.8.8.8: !

[OK - 963 bytes]


963 bytes copied in 0.001 secs (963000 bytes/sec)

Router#

%LINK-5-CHANGED: Interface GigabitEthernet0/0.50, changed state to up


%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0.50, changed state to up


%LINK-5-CHANGED: Interface GigabitEthernet0/0.60, changed state to up


%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0.60, changed state to up


%SYS-5-CONFIG_I: Configured from console by console


now backup is done to upload in our router

  Mikrotik Hotspot Configuration Initial Setup If you’re using a new Mikrotik router, we recommend resetting the device to remove the preinstalled configuration as it contains settings you will probably not need.

Adding IP Addresses to the Mikrotik Add an IP for your Hotspot network by going to IP > Addresses. Ensure you assign the IP address to the proper interface on which the switch or AP for the hotspot network will be connected. It is also best practice to put comments on the newly added subnet . Configuring the Hotspot Server To configure a hotspot server, follow these steps: Click IP ...

  In this lab, I am gonna teach you   OSPF Multi Area Configuration of 4 Routers Given Network: 192.168.0.0 Required hosts on Router 1= 100 Required hosts on Router 2= 30 Required hosts on Router 3= 6 Required hosts on Router 4= 1 R1<= 100 100<= 2 n  – 2 100<= 2 7  – 2 100<= 128 – 2 100<= 126 Total number of network bits = 32 32 – n = 32 – 7 = 25  (CIDR value of given network i.e. Router 1) i.e. 192.168.0.0/25 N.S.M = 11111111. 11111111. 11111111.10000000                         = 255.255.255.128 Block Size       = 256 – N.S.M                         = 256 – 128 = 128 Note: Add this block size in given network so that we can get our new network for Router 2. So the new network is 192.168.0.128/? N...
