Mobile IP Con guration
The Security Parameter Index (SPI) identifying the security
context for the mobile IP 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.
The used authentication algorithm. This can be pre x-su x-
md5 (default for MIP) or hmac-md5.
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.
The lifetime of security associations in seconds
Speci es whether UDP encapsulation shall be used or not. To
allow NAT traversal, UDP encapsulation must be enabled.
Optionally speci es a subnet which should be routed to the
mobile node. This information is forwarded via Network Mo-
bility (NEMO) extensions to the home agent. The home agent
can then automatically add IP routes to the subnet via the
mobile node. Note that this feature is not supported by all
third party home agent implementations.
The network mask for the optional routed network
