By default, no authentication mode is configured for an OSPF area.
Routers that reside in the same area must have the same authentication mode:
non-authentication, simple, or MD5.

Description
Use the bandwidth-reference command to specify a reference bandwidth value
for link cost calculation.
for link cost calculation.
Use the undo bandwidth-reference command to restore the default value.
The default value is 100 Mbps.
When links have no cost values configured, OSPF calculates their cost values:
Cost=Reference bandwidth value / Link bandwidth. If the calculated cost value is
greater than 65535, the maximum cost will be 65535.
Cost=Reference bandwidth value / Link bandwidth. If the calculated cost value is
greater than 65535, the maximum cost will be 65535.
