What is variance in EIGRP?
What is variance in EIGRP?
Introduction. 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.
Is EIGRP Classful or classless?
classless
Newer protocols, including RIP-2, EIGRP, and OSPF, are classless.
How do you set up a variance?
To configure the variance calculation split, go to Financial Accounting > General Ledger Accounting > Periodic Processing > Integration > Materials Management > Define Accounts for Splitting Price Differences in Configuration.
What is the variance command?
The variance command allows unequal-cost load balancing over up to 6 different paths. But here’s the key, it only works when the cost of the path is lower than the variance number multiplied by the best metric. Here is an example scenario. R1 will by default use the path through R3 because it has the lowest metric.
Which routing protocols are classless?
Only RIPv1 and IGRP are classful. All other IPv4 and IPv6 routing protocols are classless.
What is the difference between classless and classful?
Classful addressing is a technique of allocating IP addresses that divides them into five categories. Classless addressing is a technique of allocating IP addresses that is intended to replace classful addressing in order to reduce IP address depletion.
Which is the fastest routing protocol?
Many network engineers believe that EIGRP is the best choice for a routing protocol on private networks because it offers the best balance between speed, scalability and ease of management.
Is EIGRP scalable?
Scaling EIGRP with Multiple Autonomous Systems. Implementing multiple EIGRP autonomous systems is sometimes used as a scaling technique. The usual rationale is to reduce the volume of EIGRP queries by limiting them to one EIGRP autonomous system.
