How do you calculate EIGRP metric?
How do you calculate EIGRP metric?
EIGRP uses these scaled values to determine the total metric to the network: metric = [K1 * bandwidth + (K2 * bandwidth) / (256 – load) + K3 * delay] * [K5 / (reliability + K4)]
What is d ex in EIGRP?
EIGRP routes that appear with a “D” in the routing table indicate that they are intra-AS routes, and those with “D EX” indicate that they are external AS routes. No EIGRP routes in the routing table can indicate that a Layer 1 or 2 issue or an EIGRP neighbor problem exists.
How do you manipulate EIGRP metric?
R2 has 2 equal cost paths to network 192.168. 0.0/24 , 1st from interface fa0/0 and 2nd via interface fa0/1. Since Loopback0 of R1 has delay of 5000 Microseconds while Fa0/0 of R2 has delay of 1000 microseconds, hence Total DLY will be 1000 + 5000 = 6000 Microseconds.
What is offset list in EIGRP?
An offset list is the mechanism for increasing incoming and outgoing metrics to routes learned via EIGRP or Routing Information Protocol (RIP). (Offset lists are only used for distance vector routing protocols.) Optionally, an offset list can be limited by specifying either an access list or an interface.
What is administrative distance of EIGRP?
This is because EIGRP routes have (by default) the administrative distance of 90, while RIP route have a higher administrative distance of 120.
What factors are used in the calculation of the default EIGRP metric?
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.
How does EIGRP choose the bandwidth metrics for the optimal route calculation?
Bandwidth: The bandwidth value used in the EIGRP metric calculation is determined by dividing 10,000,000 by the bandwidth (in kbps) of the slowest link along the path to the destination network.
What is the K value in EIGRP?
As such, Cisco elected to only consider Bandwidth and Delay, and to weigh them equally, in their default EIGRP metric calculation. The default K-Values are K1 and K3 set to one, and K2, K4, and K5 set to zero.
