Chapter 54 Configuring Routing Policies on Firewall Devices
Configuring OSPFv3
Transmit Delay The estimated time, in seconds, required to send an LSA packet on the
interface. LSAs in the update packet have their ages increased by the
amount specified by this field before transmission. If the delay is not
added before transmission over a link, the time in which the LSA
propagates over the link is not considered. The value assigned should
take into account the transmission and propagation delays for the
interface. This setting has more significance on very low-speed links.
Valid values range from 1 to 65535 seconds.
Authentication
Type The type of authentication enabled on this interface. Choose one of the
following:
• Area – OSPFv3 does not provide “built-in” authentication, instead
relying on IPv6/IPSec protocols. Choose this option to use those
protocols to authenticate OSPFv3 traffic on all interfaces in the
area; this means all routing devices in the area must use this option.
This is the default.
• Interface – Choose this option to secure this interface and protect
OSPFv3 virtual links. The additional parameters in this section are
enabled when you choose this option.
• None – OSPFv3 authentication is disabled.
Security Parameter Index Enter an IPSec identification tag used to distinguish this particular
OSPFv3 interface; used in conjunction with the specified
authentication and encryption rules. Valid values range from 256 to
4294967295.
Authentication Algorithm Choose the type of authentication algorithm to use:
• md5 – Message Digest 5; produces a 128-bit hash value.
• sha1 – Secure Hash Algorithm version 1; produces a 160-bit hash
value.
Authentication Key Enter an authentication key. The length of the key entered depends on
the type of authentication chosen as the Authentication Algorithm, and
whether the key is to be encrypted (when you check the Encrypt
Authentication Key box):
• md5 – 32 characters.
• md5 (encrypted) – 66 characters.
• sha1 – 40 characters.
• sha1 (encrypted) – 82 characters.
Encrypt Authentication Key Check this box to require encryption of the specified Authentication
Key for transmission.
Include Encryption Check this box to require encryption of OSPFv3 packets. The following
options are enabled.
