What are the advanced features of EIGRP?
One of the more advanced features of EIGRP is Manual route summarization. It improves stability and reduces the routing table size. EIGRP routing protocol can be accessible with the CISCO network devices. EIGRP is a distance vector routing protocol, and it relies on routes provided by neighbors.
What is the EIGRP protocol?
EIGRP is a classic hybrid protocol that supports classless routing, it supports automatic & manual summarization on an EIGRP enabled interface. It MD5 authentication on routers running EIGRP and also has a maximum hop count close to 255. EIGRP performs load balancing over the equal-cost path and un-equal cost path.
What are the cons of EIGRP?
Cons of EIGRP 1 EIGRP routing protocol can be accessible with the CISCO network devices. 2 EIGRP is a distance vector routing protocol, and it relies on routes provided by neighbors. 3 It does not support future applications as it is not extensible.
Which topologies are supported by EIGRP?
Support all LAN and WAN data link protocols and topologies – EIGRP supports multi-access networks like FDDI, token ring, etc, and all WAN topologies like leased line, point-to-point links. EIGRP doesn’t require any additional configuration across layer 2 protocols like frame relay.
What are the main features of EIGRP?
The characteristics of EIGRP follow:Hybrid routing protocol (distance vector that has link-state protocol characteristics).Uses IP protocol 88.Classless protocol (supports VLSMs).Default composite metric uses bandwidth and delay.You can factor load and reliability into the metric.More items...•
What are the advantages of EIGRP?
EIGRP helps in reducing network traffic by only enabling “need-based” updates. It provides encryption for security and can be used with iBGP for WAN routing. EIGRP with protocol-dependent modules can route several different layer protocols. It performs a much easier transition with a multi-address family.
What is the use of EIGRP?
Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration.
What type of routing protocol is EIGRP?
Dynamic routing Protocol performs the same function as static routing Protocol does. In dynamic routing Protocol, if the destination is unreachable then another entry, in the routing table, to the same destination can be used. One of the routing protocols is EIGRP.
Which feature is supported by EIGRP but is not supported by OSPF?
EIGRP is the only protocol supporting unequal path load balancing which helps routers route traffic across links of different bandwidth, while OSPF does not have this feature.
What are the benefits of EIGRP compared to OSPF?
The network convergence time is faster than OSPF networks, because EIGRP network can learn the topology information and updates more rapidly. The performance of packet delay variation for EIGRP is better than for OSPF.
What are the four basic components of EIGRP?
EIGRP has four basic components:Neighbor Discovery/Recovery.Reliable Transport Protocol.DUAL Finite State Machine.Protocol Dependent Modules.
Which operation feature is different between EIGRP and Rip?
Which operation feature is different between EIGRP and RIP? EIGRP uses periodic update timers. EIGRP has a metric of hop count. EIGRP stores all routes learned from neighbors in a topology table.
What are the different types of EIGRP packets?
EIGRP sends out five different types of packets—hello, update, query, reply, and acknowledge (ACK)—that are used to establish the initial adjacency between neighbors and to keep the topology and routing tables current.
What does EIGRP stand for?

What is metric in EIGRP?
Metric calculation is a critical component for any routing protocol. EIGRP uses multiple factors to calculate the metric for a path. Metric calculation uses bandwidth and delay by default but can include interface load and reliability, too. The formula shown in Figure 2-6 illustrates the EIGRP classic metric formula.
What is active and passive state in EIGRP?
Note - The EIGRP term "active" refers to a route for which a router is currently using the Query process to find a loop-free alternative route. Conversely, a route is in passive state when it is not in an active state. The neighboring routers view any received Query messages as an input event.
What are the advantages and disadvantages of EIGRP?
EIGRP is the most advanced routing protocol that relies on distance vector, and state route links are effective in identifying the optimal route path. It will have more impact in real-time as it makes use of required resources, and the only disadvantage is that it is not extensible.
What are the advantages and disadvantages of OSPF?
OSPF Features, Advantages, DisadvantagesOSPFv2OSPFv3You can run only one instance per link.You can run many instances per link.It needs a network mask to form an adjacency.It does not need a network mask to form an adjacency.It uses MD5 hashing for authentication.It uses IPSec for authentication.6 more rows•Apr 24, 2022
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.
What is the difference between BGP and EIGRP?
In BGP, Transmission control protocol is used. It is type of mesh topology or design.It works by two independent networks (Autonomous Systems or AS) exchanging routing information....Difference between EIGRP and BGP :SR.NOEIGRPBGP7.In EIGRP, Internet protocol is used.In BGP, Transmission control protocol is used.7 more rows•Jun 22, 2020
What is EIGRP 224.0.0.10?
EIGRP uses 224.0.0.10 as it’s multicast address. For each multicast it sends, the router prepares and maintains a list of routers (speaking EIGRP). If no acknowledgement of multicast is received then same data is transmitted through 16 unicast messages.
What is EIGRP in Cisco?
Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco-proprietary hybrid routing protocol that contains features of distance-vector and link-state routing protocols. It is a network layer protocol which works on the protocol number 88.
What is EIGRP protocol?
It is a technologically, more advanced distance vector-based routing protocol. To exchange information using EIGRP, first and foremost, the routers need to become neighbors to EIGRP, then EIGRP uses the multicast address to share the information.

What is EIGRP in Cisco routers?
Enhanced Interior Gateway Routing Protocol or EIGRP automates the routing decisions and configurations in computer networking. Cisco designed the protocol and is available only on Cisco routers. Minimum bandwidth is used from the source to destination, and the delay is measured using metrics of the network. This is an advanced protocol to measure the distance and uses both link servicing and distance routing. Hence it is called a hybrid protocol. It transitions well with IPv6 and has the support of IPv4 as well. This is a classless routing technique. Two routers are connected, and the network is shared in EIGRP.
What is EIGRP load balancing?
EIGRP performs load balancing over the equal-cost path and un-equal cost path. To perform the functions of EIGRP, it creates three tables which are: Following represents the ideology and concepts behind the three major tables: 1.
What does hello mean in router?
Hello: It determines the neighbors’ router and also serves as a keep-alive mechanism between the routers. If Router X is connected with Router Y and the Router X is not receiving the hello packets from Router Y, then it assumes that Router Y is not reachable and the network is down.
