Parameter
Mobile IP Node Configuration
SPI
The Security Parameter Index (SPI) identifying the security
context for the tunnel between the
mobile node
and the
home
agent
.
This is used to distinguish mobile nodes from each
other. Therefore each
mobile node
needs to be assigned a
unique SPI. This is a 32-bit hexadecimal value.
Authentication type
The used authentication algorithm. This can be prefix-suffix-
md5 (default for mobile IP) or hmac-md5.
Shared secret
The shared secret used for authentication of the
mobile node
at the
home agent
. This can be either a 128-bit hexadecimal
value or a random length ASCII string.
