Description Use the authentication-mode command to specify an authentication mode for
the OSPF area.
Use the undo authentication-mode command to cancel a specified
authentication mode.
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.
Related commands: ospf authentication-mode .
Examples # Specify the MD5 ciphertext authentication mode for OSPF area0.

Parameters value : Specifies a bandwidth reference value for link cost calculation, in the range
1 to 2147483648 Mbps.
Description Use the
bandwidth-reference
command to specify a reference bandwidth value
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.
Examples # Specify the reference bandwidth value as 1000 Mbps.
