Cost Tuning of OSPF

NLRI - Multilevel Level Reachability Details

OSPF channels are usually primarily grouped based on the metric, the spot that the Metric along with Charge are usually computed based solely about the Website link Bandwidth.

Charge = 100/(BW[Mbps])

You will find a couple of points you could potentially participate in with here:

1. Set your REFERENCE BW (because while using solution earlier mentioned your Utmost charge benefit can be 1, along with we all won't would like exactly the same values for 100M along with 10G link)

(config-router)#auto-cost reference-bandwidth 10000

*10000 can be 10000 Mbps

* Please don't forget to be able to apparent your OSPF practice in order that your alterations for taking effect:

#clear ip ospf practice

a couple of. Alter the price inside the Interface Setting

(config-if)#ip ospf charge 20

along with check the actual result:

Cisqueros_R1#show ip ospf inter Lo0 | i Charge
Procedure IDENTIFICATION 1, Router IDENTIFICATION 1. 1. 1. 1, Multilevel Variety POINT_TO_POINT, Charge: 20

Next check your metric about the OSPF Neighbor:

Cisqueros_R2#show ip route 1. 0. 0. 0
Direction-finding entry for 1. 0. 0. 0/8
Identified via "ospf 1", range 110, metric 84, kind intra place <--- METRIC 84
Very last up-date from 10. 1. 12. 1 in Serial1/0. 7, 00: 02: 31 in the past
Direction-finding Descriptor Hinders:
* 10. 1. 12. 1, from 1. 1. 1. 1, 00: 02: 31 in the past, via Serial1/0. 7
Course metric can be 84, visitors write about rely can be 1

Metric can be 84, and that is the cost of your Serial program in between routers 1 along with a couple of, along with the cost of your Loopback0 program in Router 1.

Default charge of the Loopback program can be 1, in order that it actually improved for 20-1 = twenty.
