AREA AUTHENTICATION IPSEC SPI

area authentication ipsec spi
Overview Use this command in Router Configuration mode to enable either MD5
(Message-Digest 5) or SHA1 (Secure Hash Algorithm 1) authentication for a
specified OSPF area.
Use the no variant of this command in Router Configuration mode to disable the
authentication configured for a specified OSPF area.

Usage Use this command on an OSPFv3 area, use the
ipsec spi
Parameters Index) value on all interfaces that connect to the same link. SPI values
are used by link interfaces. Use a different SPI value for a different link interface
when using OSPFv3 with link interfaces.
Use the sha1 keyword to choose SHA-1 authentication instead of entering the
md5 keyword to use MD5 authentication. The SHA-1 algorithm is more secure
than the MD5 algorithm. SHA-1 uses a 40 hexadecimal character key instead of a
32 hexadecimal character key as used for MD5 authentication.

Parameter Description
<area-id>
The OSPF area that you are specifying the summary route default-
cost for. This can be entered in either dotted decimal format or
normal decimal format. Use one of the following formats:
<ip-addr>
<0-4294967295>
For example, the values 0.0.1.2 and decimal 258 would both define
the same area-ID.
<256-
