Administrative distance the word you always hearing whenever you heard about the routing Protocols and you are very much aware of the AD values of all the routing protocols. These AD values are come into picture whenever you have Cisco routers and you are implementing the routing protocols on the top of it.
Apart from Cisco, when we have Juniper, HP or Huawei routers then the values actually changes.
