Spanning tree uses cost to determine the shortest path to the root bridge. The slower the interface, the higher the cost is. The path with the lowest cost will be used to reach the root bridge. Here’s where you can find the cost value: In the BPDU, you can see a field called root path cost.
14 lip 2008 · It is used to determine which route is the most believable in the case of two protocols having the same network. For example if you had a route from RIP to 10.0.0.0/24 and a route from IGRP to the same network, you cannot directly compare the metrics as they are calculated differently.
18 sty 2022 · It contains spanning-tree path cost value or root path cost value which is used to determine the root port of the switch. BPDU Spanning tree path cost value can be defined as the sum of the port costs of all the ports included in the path from non-root switch to root switch.
14 sty 2017 · The Metric field indicates the cost of a route. If multiple routes exist to a given destination network ID, the metric is used to decide which route is to be taken. The route with the lowest metric is the preferred route.
Understand and master the EIGRP Metric formula and how to calculate it. The ultimate resource to explain the EIGRP cost calculation.
31 sie 2023 · EIGRP puts up to four routes of equal cost in the routing table, which the router then load balances. The type of load balance (per packet or per destination) depends on the type of switching that is done in the router. EIGRP, however, can also load balance over unequal cost links.
9 cze 2024 · It runs the SPF algorithm on all paths to calculate the cost of all paths. It selects the path having the least cost for every destination and adds it to the routing table. A destination may have multiple paths.
