Parameters
• process-id—Enter an OSPFv3 process ID for a specic OSPFv3 process (1 to 65535).
• area-id—Enter the OSPFv3 area ID in dotted decimal format (A.B.C.D) or enter an area ID number (1 to
65535).
Default Not congured
Command Mode INTERFACE
Usage Information The no version of this command removes an interface from an OSPFv3 area.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# ipv6 ospf 10 area 1
Supported Releases 10.3.0E or later
ipv6 ospf authentication
Congures OSPFv3 authentication on an IPv6 interface.
Syntax
ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} key}
Parameters
• null — Prevents area authentication from being inherited on the interface.
• ipsec spi number — Enter a unique security policy index number (256 to 4294967295).
• md5 — Enable MD5 authentication.
• sha1 — Enable SHA-1 authentication.
• key — Enter the text string used by the authentication type.
Default IPv6 OSPF authentication is not congured on an interface.
Command Mode INTERFACE
Usage Information
• Before you enable IPsec authentication on an OSPFv3 interface, you must enable IPv6 unicast routing globally,
congure an IPv6 address and enable OSPFv3 on the interface, and assign it to an area.
• The SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. You
cannot congure the same SPI value on another interface even if it uses the same authentication or encryption
algorithm.
• You cannot use an IPsec authentication type (MD5 or SHA-1) and the null setting at same time on an
interface. These settings are mutually exclusive.
• All neighboring OSPFv3 routers must share the 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 authentication ipsec spi 400 md5
