What transport protocol does EIGRP use?
As a result, end systems will not affected by the routing updates and queries. – EIGRP is a transport layer protocol that relies on IP packets to deliver its routing information. EIGRP packets are encapsulated in IP packets with the Protocol Number field value 88 (0x58) in the IP header.
What is the purpose of EIGRP routing 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).
Which routing protocol does Cisco use?
Cisco has created its own routing protocol – EIGRP. EIGRP is considered to be an advanced distance vector protocol, although some materials erroneously state that EIGRP is a hybrid routing protocol, a combination of distance vector and link state.
Is EIGRP still used?
EIGRP is known widely as a proprietary protocol. While it’s true that the informational RFC by Cisco will allow other vendors to use EIGRP as a routing protocol, the adoption of EIGRP by other vendors is still quite distant, if it ever happens at all.
Is Rip a routing protocol?
Routing Information Protocol (RIP) is a distance-vector routing protocol. Routers running the distance-vector protocol send all or a portion of their routing tables in routing-update messages to their neighbors. You can use RIP to configure the hosts as part of a RIP network.
Does rip use UDP or TCP?
RIP uses User Datagram Protocol (UDP) port 520. RIP has the following architectural limitations: The longest network path cannot exceed 15 hops (assuming that each network, or hop, has a cost of 1).
What is OSPF and EIGRP?
EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are two common Interior Gateway Protocols (IGP) specifying how routers or data switches communicate with each other. They are often applied in different situations for varied performance on speed, delay, etc.
What is the difference between OSPF and EIGRP?
EIGRP is a proprietary gateway protocol that contains optimisations intended to minimise routing instability incurred after topology changes; OSPF is a dynamic routing protocol that is used specifically for the IP networks. 2. EIGRP collects data in three tables; OSPF routes IP packets within a single routing domain.
How many protocols are there in CCNA?
Common routing protocols include RIP, RIPv2, IGRP, EIGRP, IS-IS and BGP. For the CCNA exam you will need to be well versed in RIP, RIPv2, IGRP and EIGRP. You should be aware of IS-IS and BGP, and be able to configure basic OSPF. Two main types of routing protocols exist – distance vector and link state.
What is Cisco RIP protocol?
The Routing Information Protocol (RIP) sends routing-update messages at regular intervals and when the network topology changes. When a device receives a RIP routing update that includes changes to an entry, the device updates its routing table to reflect the new route.
What four routed protocols are supported by EIGRP?
The four routed protocols supported by EIGRP are IP, IPv6, IPX, and AppleTalk. 2. Redistribution is required when more than one EIGRP session or process is running and they are identified with different ASNs. Redistribution shares topology information between EIGRP sessions. 3. router eigrp 300. 4. network 184.108.40.206. 5. Passive interface. 6
How to configure EIGRP on Cisco router step by step?

How to set default route with EIGRP?
Configure an offset-list on R4 that increases (by 20) the delay for any route starting with 10.1.3.x.
How to configure EIGRP over the top routing (OTP)?
