DETAILED STEPS
Configuring Authentication Message Digest Management for OSPF
This task explains how to manage authentication of a keychain on the OSPF interface.
Prerequisites
A valid keychain must be configured before this task can be attempted.
To learn how to configure a keychain and its associated attributes, see the “Implementing Key Chain
Management on Cisco IOS XR Software” module of Cisco IOS XR System Security Configuration
Guide.
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
Enables OSPF routing for the specified routing process and
places the router in router configuration mode.
Note The process-name argument is any alphanumeric
string no longer than 40 characters.
Step 3
mpls ldp auto-config
Example:
RP/0/RP0/CPU0:router(config-ospf)# mpls ldp
auto-config
Enables LDP IGP interface auto-configuration for an OSPF
instance.
• Optionally, this command can be configured for an area
of an OSPF instance.
Step 4
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-ospf)# end
or
RP/0/RP0/CPU0:router(config-ospf)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
