OSPFv3 neighbor authentication 6.2.1

This feature adds OSPFv3 neighbor authentication for IPv6 enhanced security.

The following CLI commands are added for authentication for OSPF6 interface:

config router ospf6
    config ospf6-interface
        edit <name>
            set authentication {none | ah | esp | area}
            set key-rollover-interval <integer>
            set ipsec-auth-alg {md5 | sha1 | sha256 | sha384 | sha512}
            set ipsec-enc-alg {null | des | 3des | aes128 | aes192 | aes256}
            config ipsec-keys
                edit <spi>
                    set auth-key <string>
                    set enc-key <string>
                next
            end
        next
    end
end

The following CLI commands are added for authentication for OSPF6 virtual-link:

config router ospf6
    config area
        edit <id>
            config virtual-link
                edit <name>
                    set authentication {none | ah | esp | area}
                    set key-rollover-interval <integer>
                    set ipsec-auth-alg {md5 | sha1 | sha256 | sha384 | sha512}
                    set ipsec-enc-alg {null | des | 3des | aes128 | aes192 | aes256}
                    config ipsec-keys
                        edit <spi>
                            set auth-key <string>
                            set enc-key <string>
                        next
                    end
                next
            end
        next
    end
end

The following CLI commands are added for authentication for OSPF6 area configuration:

config router ospf6
    config area
        edit <id>
            set authentication {none | ah | esp}
            set key-rollover-interval <integer>
            set ipsec-auth-alg {md5 | sha1 | sha256 | sha384 | sha512}
            set ipsec-enc-alg {null | des | 3des | aes128 | aes192 | aes256}
            config ipsec-keys
                edit <spi>
                    set auth-key <string>
                    set enc-key <string>
                next
            end
        next
    end
end

CLI command descriptions

Command	Description
<id>	Area entry IP address.
authentication {none | ah | esp | area}	Authentication mode: none: Disable authentication ah: Authentication Header esp: Encapsulating Security Payload area: Use the routing area's authentication configuration
key-rollover-interval <integer>	Enter an integer value (300 - 216000, default = 300).
ipsec-auth-alg {md5 | sha1 | sha256 | sha384 | sha512}	Authentication algorithm.
ipsec-enc-alg {null | des | 3des | aes128 | aes192 | aes256}	Encryption algorithm.
<spi>	Security Parameters Index.
auth-key <string>	Authentication key should be hexadecimal numbers. Key length for each algorithm: MD5: 16 bytes SHA1: 20 bytes SHA256: 32 bytes SHA384:48 bytes SHA512:84 bytes If the key is shorter than the required length, it will be padded with zeroes.
enc-key <string>	Encryption key should be hexadecimal numbers. Key length for each algorithm: DES: 8 bytes 3DES: 24 bytes AES128: 16 bytes AES192: 24 bytes AES256: 32 bytes If the key is shorter than the required length, it will be padded with zeroes.
