What is MD5 authentication in RIP?

What is MD5 authentication in RIP?

Authentication requires all routers within the RIP network or subnetwork to have the same authentication type and key (password) configured. This type of authentication is not supported on RIPv1 networks. MD5 authentication uses an encoded MD5 checksum that is included in the transmitted packet.

Which of the following commands enables RIP authentication?

The no shutdown (RIP) command in router-RIP configuration mode will enable RIP. This command enables RIP on the switch. Issuing this command enables RIP, but to send and receive RIP route updates and to route packets via RIP you must also specify interfaces on which RIP will run by using the network (RIP) command.

What are the steps required to configure RIPv2 authentication?

RIPv2 Authentication – Configuration Steps

1. Define a key chain with a name.
2. Define the key or keys on the key chain and specify the password or key-string to be used in the key.
3. Enable authentication on an interface and specify the key chain to be used.

What is Eigrp protocol?

Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol that enables routers to exchange information more efficiently than earlier network protocols, such as Interior Gateway Routing Protocol (IGRP) or Border Gateway Protocol (BGP).

How do I configure RIP routing?

To configure a basic RIP network:

1. Configure the network interfaces. This example shows multiple loopback interface addresses to simulate attached networks.
2. Create the RIP group and add the interface.
3. Create the routing policy to advertise both direct and RIP-learned routes.
4. Apply the routing policy.

How do I check my RIP version?

The commands used to verify the operation of the RIP version 2 is as follows:

1. Show ip route. This command will assist to determine the network of the IP address which is currently as either remotely or directly connected.
2. Show ip protocols.
3. Debug ip rip.
4. Show ip interface brief.
5. Ping.
6. Show running-config.

How do you implement RIPv2?

Configuring RIPv2

Configuring RIP routing protocol consists of three basic steps: Enabling RIP routing protocol on the router. Specifying the RIP version to run. Configuring the network addresses to be included in routing updates or specifying the interfaces to participate in routing updates.

What is RIP v2?

The Routing Information Protocol, version 2 (RIPv2) is an enhanced version of RIP that includes support for important routing features such as class-less addressing and variable-length subnet masks [37]. RIPv2 is a distance-vector protocol that has been in use for many years.

What is BGP port number?

BGP neighbors, called peers, are established by manual configuration among routers to create a TCP session on port 179.

Which is a difference between RIP version 1 and RIP version 2?

RIP v1 is an older, no longer much used routing protocol. RIP v2 is a classless protocol and it supports classful, variable-length subnet masking (VLSM), CIDR, and route summarization. RIPv2 supports authentication of RIPv2 update messages (MD5 or plain-text).

What is RIP v2 protocol?

RIPv2 is a classless, distance vector routing protocol as defined in RFC 1723. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. As with other classless routing protocols, RIPv2 supports CIDR supernets, VLSM, and discontiguous networks.

What is difference between RIPv1 and v2?

What is the difference between RIP version 1 and 2?

RIP v1 does not support authentication of update messages (plain-text or MD5). RIP v1 is an older, no longer much used routing protocol. RIP v2 is a classless protocol and it supports classful, variable-length subnet masking (VLSM), CIDR, and route summarization.

What information is found in a RIP v2 update but not in a RIPv1 update?

There are currently two IPv4 RIP versions: Version 1 and Version 2. The main difference between v1 and v2 is that v2 supports subnet masks and authentication. RIP uses a metric called hops to determine the cost of a route. A hop is viewed as a router which the traffic must pass through.

Is BGP Layer 3 or 4?

BGP in networking is based on TCP/IP. It operates on the OSI Transport Layer (Layer 4) to control the Network Layer (Layer 3).

Is BGP TCP or UDP?

TCP
BGP uses TCP port 179 to communicate with other routers. TCP allows for handling of fragmentation, sequencing, and reliability (acknowledgement and retransmission) of communication packets.

How do you implement RIP v2?

What is RIP v2 in networking?

RIPv2. RIPv2 stands for hybrid routing protocol version 2. It is a distance-vector routing protocol defined in RFC 1723 and has the characteristics of link-state routing protocols. It is a classless routing protocol which means it involves the subnet mask having the network addresses in the routing updates.

Which three statements describe the difference between RIP version 1 and RIP version 2?

RIP version 1 broadcasts updates whereas RIP version 2 uses multicasts. C. RIP version 1 multicasts updates while RIP version 2 uses broadcasts.

How does RIP version 2 work?

What layer is DNS in OSI?

layer 7
In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.

Why RIP is Layer 7 protocol?

RIP is responsible for announcing changes in routes between routers. Layer 7 is the application layer, which is what the user touches. Layer 3 is the network layer where routing and IP both reside. RIP is not a userland process; users do not interact with it, and user-level applications do not interact with it.

What port is RIP?

520
Routing Information Protocol (RIP) is a dynamic routing protocol that uses hop count as a routing metric to find the best path between the source and the destination network. It is a distance-vector routing protocol that has an AD value of 120 and works on the Network layer of the OSI model. RIP uses port number 520.

What are two characteristics of RIP v2?

The characteristics of RIPv2 follow:

• Distance-vector protocol.
• Uses UDP port 520.
• Classless protocol (support for CIDR).
• Supports VLSMs.
• Metric is router hop count.
• Maximum hop count is 15; infinite (unreachable) routes have a metric of 16.
• Periodic route updates sent every 30 seconds to multicast address 224.0.

Is DNS a TCP or UDP?

DNS uses TCP for Zone transfer and UDP for name, and queries either regular (primary) or reverse. UDP can be used to exchange small information whereas TCP must be used to exchange information larger than 512 bytes.
