Is RIP version 2 classless or classful?

First, RIP version 2 is a classless routing protocol. Classless routing protocols always advertise the subnet mask in their routing updates.

What does Auto Summary do in RIP?

Auto summarization is a feature which allows Routing Information Protocol (RIP) to summarize its routes to their classful networks automatically.

Does RIP support classless?

RIP v2 is a classless protocol and it supports classful, variable-length subnet masking (VLSM), CIDR, and route summarization.

What is Auto summary in Eigrp?

EIGRP supports automatic summarization which as the name implies means that it will automatically advertise summary routes to other EIGRP routers. EIGRP will check if you have any subnets that fall within the range of your network command(s) and if so, it will advertise the classful A, B or C network to its neighbors.

Is OSPF classless?

The classless IPv4 routing protocols (RIPv2, EIGRP, OSPF, and IS-IS) all include the subnet mask information with the network address in routing updates. Classless routing protocols support VLSM and CIDR. IPv6 routing protocols are classless.

Should I enable RIP on my router?

RIP is a dynamic routing protocol. Unless you have multiple routers you need to distribute routes to there really isn’t any reason to run it. All it will do is put extra traffic on the wire and eat up a few cpu cycles on your router. The con to using it is that it will flood your network with updates periodically.

Why do we use no auto-summary in RIP?

RIP Version 1 always uses automatic summarization. If you are using RIP Version 2, you can turn off automatic summarization by specifying no auto-summary. Disable automatic summarization if you must perform routing between disconnected subnets. When automatic summarization is off, subnets are advertised.

How does RIP Summarise routes?

RIP automatically summarizes along classful network boundaries. So if your router sees that several subnets of the same network all use the same path, and there are no subnets of this network using a different path, it will automatically summarize this information. The routes to the individual subnets are suppressed.

What is the main disadvantage of using RIP?

The disadvantages of RIP include: Increased network traffic: RIP checks with its neighboring routers every 30 seconds, which increases network traffic. Maximum hop count: RIP has a maximum hop count of 15, which means that on large networks, other remote routers may not be able to be reached.

How do I turn off auto-summary in EIGRP?

Each router is advertising each other about the same network. To turn off Auto summarization feature in Enhanced Interior Gateway Routing Protocol (EIGRP), we can use the “no auto-summary” command from the Router Configuration mode.

Why OSPF is classless?

OSPF is a classless routing protocol, which means that in its updates, it includes the subnet of each route it knows about, thus, enabling variable-length subnet masks.
