How does variance work in EIGRP?
How does variance work in EIGRP?
EIGRP provides a mechanism to load balance over unequal cost paths throungh Variance Command. Variance is a number (1 to 128), multiplied by the local best metric then includes the routes with the lesser or equal metric. The default Variance value is 1, which means equal-cost load balancing.
How many unequal-cost paths does EIGRP?
six unequal-cost paths
If a path is not a feasible successor, it is not used in load balancing. EIGRP supports up to six unequal-cost paths.
What are the disadvantages of EIGRP?
Cons of EIGRP
- 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.
- It does not support future applications as it is not extensible.
What is EIGRP and how it works?
How EIGRP Works Neighbor Relationship. A router discovers a neighbor when it receives its first hello packet on a directly connected network. Reliable Transport Protocol. Diffusing Update Algorithm (DUAL) All route computations in EIGRP are handled by DUAL. Protocol-Dependent Module. EIGRP Packet Format.
What are the k values represent In EIGRP?
EIGRP Metric K Values Explained with Examples Bandwidth (K1) Bandwidth is a static value. It will change only when we make some physical (layer1) changes in route such as changing cable or upgrading link types. Load (K2) Load is a dynamic value that changes frequently. It is based on packet rate and bandwidth of interface. EIGRP Metric Calculation Formula.
What does EIGRP mean?
EIGRP is a Cisco proprietary routing protocol loosely based on their original IGRP (Interior Routing Protocol). EIGRP is an advanced distance-vector routing protocol, it can only use it in an all-Cisco network, but EIGRP more than makes up for this deficiency by being easy to configure, fast, and reliable.
What is the formula for price variance?
Price variance is the difference between the actual price paid by a company to purchase an item and its standard price, multiplied by the number of units purchased. The formula for price variance is: Price variance = (actual price – standard price) x actual quantity.
