OSPF Unit 1: Chapter: Introduction to OSPF | Reference Bandwidth & Interface Bandwidth
I went through your video & Notes, i tried much, But I am not understanding,
- What is Reference Bandwidth & Interface Bandwidth in OSPF?
let me tell you, correct me please if i am wrong.
As per my understanding:
Interface Bandwidth Means: Device/ Router Physical Interface Bandwidth. Isn’t it?
Ex: 1000Mb: Gig0/0, 100Mb: Fa0/0, 10Mb: Eth0/0. Am i rite?
Reference Bandwidth Means: It is the Link Bandwidth. Isn’t it?
Ex: Internet Link: 50Mbps, MPLS Link: 10Mbps, P2P Link:2Mbps, Leased Line: 40Mbps. Am i rite?
I dint understand the below sentence in the OSPF Chapter, Unit 1: Chapter: Introdcution to OSPF
The reference bandwidth is a default value on Cisco routers which is a 100Mbit interface. You divide the reference bandwidth by the bandwidth of the interface and you’ll get the cost.
Acc to you: what is reference bandwidth is a default value on Cisco routers*?
Hope you would help me soon.
