📈 Configuring OSPF Reference Bandwidth | Explained with Examples

By default, the reference bandwidth is 100 Mbps.

Formula:
Cost = reference bandwidth / interface bandwidth

Example:
Cost = 100,000 kbps/100,000 kbps = 1

To adjust the reference bandwidth, use the auto-cost reference-bandwidth Mbps router configuration command.
This command must be configured on every router throughout the entire network.

CONFIGURE:
R1:
conf t
router ospf 1
auto-cost reference-bandwidth 1000
end
wr

VERIFY:
show run all | sec router ospf 1 !To check the default auto-cost reference-bandwidth 100.
show ip ospf | include Reference !To check the reference bandwidth.
show interfaces gig 0/0 | include BW
show ip ospf interface gig 0/0 | include Cost !To check the cost.
