Reference Guide
• When you congure encryption on an interface, both IPsec encryption and authentication are enabled. You
cannot congure encryption if you have already congured an interface for IPsec authentication (ipv6 ospf
authentication ipsec). To congure 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
SHA-1 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

OS10(config)# interface ethernet 1/1/5
OS10(conf-if-eth1/1/5)# ipv6 ospf encryption null
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 (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
