ipv6 ospf authentication ipsec command. To congure encryption, you must rst delete the
authentication policy.
• All neighboring OSPFv3 routers must share the same encryption key to decrypt information. Only a non-
encrypted key is supported. Required lengths of the non-encrypted key are: 3DES — 48 hex digits; DES — 16
hex digits; AES-CBC — 32 hex digits for AES-128 and 48 hex digits for AES-192.
• All neighboring OSPFv3 routers must share the same authentication key to exchange information. Only a non-
encrypted key is supported. For MD5 authentication, the non-encrypted key must be 32 plain hex digits. For
SHA1 authentication, the non-encrypted key must be 40 hex digits. An encrypted key is not supported.
Example
OS10(config)# interface ethernet 1/1/6
OS10(conf-if-eth1/1/6)# ipv6 ospf encryption ipsec spi 500 esp des

Supported Releases 10.4.0E(R1) or later
ipv6 ospf hello-interval
Sets the time interval between hello packets sent on an interface.
Syntax
ipv6 ospf hello-interval seconds
Parameters seconds — Enter the hello-interval value in seconds, from 1 to 65535.
Default 10 seconds
Command Mode INTERFACE
Usage Information All routers in a network must have the same hello time interval between the hello packets. The no version of the
this command resets the value to the default.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# ipv6 ospf hello-interval 30
Supported Releases 10.3.0E or later
ipv6 ospf network
Sets the network type for the interface.
Syntax
ipv6 ospf network {point-to-point | broadcast}
Parameters
• point-to-point — Sets the interface as part of a point-to-point network.
• broadcast — Sets the interface as part of a broadcast network.
Default Broadcast
Command Mode INTERFACE
Usage Information The no version of this command resets the value to the default.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ipv6 ospf network broadcast
Supported Releases 10.3.0E or later
