Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Sets the security TTL value in the IP header for OSPF packets.
security ttl [ disable | hops hop-count ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar-if)#
security ttl hopes 2
Step 9
commit
Step 10
Displays OSPF interface information.
show ospf [ process-name ] [ vrf vrf-name ] [ area-id
] interface [ type interface-path-id ]
Step 11
Example:
RP/0/RSP0/CPU0:router# show ospf 1 interface
GigabitEthernet0/5/0/0
Examples
The following is sample output that displays the GTSM security TTL value configured on an OSPF interface:
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
