Cisco IOS XR Routing Configuration Guide
Examples
The following is sample output that displays the GTSM security TTL value configured on an OSPF 
interface:
RP/0/RP0/CPU0:router# show ospf 1 interface GigabitEthernet0/5/0/0
GigabitEthernet0/5/0/0 is up, line protocol is up 
 Internet Address 120.10.10.1/24, Area 0 
 Process ID 1, Router ID 100.100.100.100, Network Type BROADCAST, Cost: 1
 Transmit Delay is 1 sec, State BDR, Priority 1 
 TTL security enabled, hop count 2
 Designated Router (ID) 102.102.102.102, Interface address 120.10.10.3
 Backup Designated router (ID) 100.100.100.100, Interface address 120.10.10.1
 Flush timer for old DR LSA due in 00:02:36
 Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
 Hello due in 00:00:05
 Index 1/1, flood queue length 0
 Next 0(0)/0(0)
 Last flood scan length is 1, maximum is 4
 Last flood scan time is 0 msec, maximum is 0 msec
 Neighbor Count is 1, Adjacent neighbor count is 1
 Adjacent with neighbor 102.102.102.102 (Designated Router)
 Suppress hello for 0 neighbor(s)
 Multi-area interface Count is 0

or
commit
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-if)# end
or
RP/0/RP0/CPU0:router(config-ospf-ar-if)# 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.
