Routing Information Protocol (RIP) on Huawei Routers

Routing Information Protocol (RIP) is belong to Distance Vector category of dynamic routing protocol. In today's enterprises network it is mostly replaced by OSPF and EIGRP. But you may encounter this in legacy network where due to some reason its not possible to it. Theory related to RIP is as you have study from any other vendor because it is a Standard routing protocol based on RFC 2453. We will be configuring RIP on the following topology.

Fist we will configure IP addresses as per the Topology:

As RIP is configured on all three routers now we can confirm by looking at their routing table.

There is some variation related to RIP metric which we can manipulate only if we have multiple links. Which we will discuss in later tutorial.
