1110 CHAPTER 76: OSPF CONFIGURATION COMMANDS

Description Use the authentication-modecommand to specify an authentication mode for the OSPF area.

Use the undo authentication-modecommand 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.

<Sysname> system-view [Sysname] ospf 100 [Sysname-ospf-100] area 0

[Sysname-ospf-100-area-0.0.0.0] authentication-mode md5

bandwidth-reference (OSPF view)

Syntax bandwidth-reference value

undo bandwidth-reference

View OSPF view

Parameters value: Specifies a bandwidth reference value for link cost calculation, in the range 1 to 2147483648 Mbps.

Description Use the bandwidth-referencecommand to specify a reference bandwidth value for link cost calculation.

Use the undo bandwidth-referencecommand 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.
