OSPF Interface Cost
Closed, ResolvedPublicBUG

Description

OSPF assign a cost values for each interface type/speed.

Actually, though configured as Ethernet/10Mbits/s, VyOS interface assumes an OSPF cost of 1.

Event Timeline

@ronie For OSPF bandwidth use command:

vyos@r4-roll# set interfaces ethernet eth0 ip ospf bandwidth 
Possible completions:
   <1-100000>   Bandwidth in megabits/sec (for calculating OSPF cost)

Not speed interface.

@Viacheslav I supposed that by default Ethernet Interfaces/10Mbits should be assigned a cost of 10 without changing any parameter. So it is not a bug? Should I cancel this request?

Not speed interface.

It was all a confusion on interface naming. When Cisco says Ethernet, they mean an Ethernet interface of 10M, that's not the case for VyOS. In VyOS eth means the interface uses the Ethernet protocol, but it could have any speed.

So, cost calculations were ok.
