Enabling Strict-Mode - Cisco ASR 9000 Series Routing Configuration Manual

Implementing OSPF
• Due to the dependency on BFD, OSPF operating in strict-mode may experience delayed neighbor

Enabling strict-mode

The following procedure describes how to enable BFD strict-mode for Open Shortest Path First (OSPF) on
an interface:
SUMMARY STEPS
1. configure
2. router ospf process-name
3. area area-id
4. interface type interface-path-id
5. bfd fast-detect strict-mode
6. commit
7. show ospf interface type interface-path-id
DETAILED STEPS
Command or Action
Step 1
configure
Example:
RP/0/RSP0/CPU0:router# configure
Step 2 router ospf process-name
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
Step 3
area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)#
Step 4 interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#

Purpose
Enters global configuration mode.
Enters OSPF configuration mode, allowing you to configure
the OSPF routing process.
Use the show ospf command in EXEC configuration mode to
obtain the process-name for the current router.
Configures an Open Shortest Path First (OSPF) area.
Replace area-id with the OSPF area identifier.
area 0
Enters interface configuration mode and specifies the interface
name and notation rack/slot/module/port.
The example indicates a Gigabit Ethernet interface in modular
