Version Description
8.3.19.0 Introduced on the S4820T.
Usage Information
By default, the dead interval is four times longer than the default hello-interval.
Related Commands
• ipv6 ospf hello-interval – specify the time interval between hello packets.
ipv6 ospf encryption
Congure an IPsec encryption policy for OSPFv3 packets on an IPv6 interface.
Syntax
ipv6 ospf encryption {null | ipsec spi number esp encryption-algorithm [key-
encryption-type] key athentication-algorithm [key-encryption-type] key}}
Parameters
null Causes an encryption policy congured for the area to not be inherited on the interface.
ipsec spi number Security Policy index (SPI) value that identies an IPsec security policy. The range is from
256 to 4294967295.
esp encryption-
algorithm
Encryption algorithm used with ESP.
Valid values are: 3DES, DES, AES-CBC, and NULL.
For AES-CBC, only the AES-128 and AES-192 ciphers are supported.
key-encryption-
type
(OPTIONAL) Species if the key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key
Text string used in authentication.
The required lengths of a non-encrypted or encrypted key are:
3DES - 48 or 96 hex digits; DES - 16 or 32 hex digits; AES-CBC -32 or 64 hex digits for
AES-128 and 48 or 96 hex digits for AES-192.
authentication-
algorithm
Species the authentication algorithm to use for encryption. Valid values are MD5 or
SHA1.
key-encryption-
type
(OPTIONAL) Species if the authentication key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key
Text string used in authentication.
