Configuring the Local Authentication Attributes
for the Mobile Node
You specify for each mobile node
several attributes that enable authentication of registration requests
from the node. These attributes include security association context
for the peering relationship, the entity type of the node, the encryption
algorithm and key used to authenticate the request, and replay protection.
To configure authentication attributes for
the mobile node:
Configure the peer entity for the security parameter.
[edit services mobile-ip]
user@host# set peer ip-address 10.4.2.20 spi 500 entity-type mobility-agent
Configure the algorithm used for authenticating
Mobile IP messages. By default, the hmac-md5 algorithm is used.
Configure the authentication key for
the security association, in either HEX or ASCII format.
[edit services mobile-ip]
user@host# set peer ip-address 10.4.2.20 spi 500 key ascii

Configure a timestamp tolerance for registration
replay protection or specify that the timestamp tolerance be taken
from the value configured on the home agent.
