How to Implement OSPF on Cisco IOS XR Software
RC-293
Cisco IOS XR Routing Configuration Guide
Step 5
nsf {cisco [enforce global] | ietf [helper
disable]}
Example:
RP/0/RP0/CPU0:router(config-ospf)# nsf ietf
(Optional) Configures NSF OSPF protocol.
The example enables graceful restart.
Step 6
timers throttle spf spf-start spf-hold
spf-max-wait
Example:
RP/0/RP0/CPU0:router(config-ospf)# timers
throttle spf 500 500 10000
(Optional) Sets SPF throttling timers.
Step 7
area area-id
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 1
Enters area configuration mode.
The area-id argument can be entered in dotted-decimal or
IPv4 address notation, such as area 1000 or area 0.0.3.232.
However, you must choose one form or the other for an area.
We recommend using the IPv4 address notation.
Step 8
interface type instance
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface
GigabitEternet0/5/0/0
Enters interface configuration mode and associates one or
more interfaces to the area.
Step 9
security ttl [disable | hops hop-count ]
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-if)# security
ttl hopes 2
Sets the security TTL value in the IP header for OSPF
packets.
