no ip mobile home-agent

#### Release Information

Command introduced in JunosE Release 9.0.0.

#### Description

Configures the Mobile IP home agent on a virtual router. Issuing this command does not affect existing parameters such as lifetime, replay value, or care-of-access ACL for any mobile node's existing binding. The new parameters take effect only upon each re-registration or new registration. For example, configuring a shorter lifetime does not cause an existing binding to be removed prematurely, but the new lifetime value is used only upon re-registration by a mobile node so that both the mobile node and the home agent are informed of the newly negotiated value. The no version disables the home agent service on the virtual router.

| Note: The values for lifetime, replay, and care-of access configured per mobile host by using the ip mobile host command override the values configured by using the ip mobile home-agent command.

#### Options

- acl—Name of the access control list applied to the care-of-access, which restricts access for foreign agents or networks. You can override this care-of-access ACL with other ACLs for specific host mobile nodes. By default, the router does not apply a care-of-access ACL
- lifetimeSeconds—Maximum number of seconds, in the range 5–65535, during which registration requests are established; default value is 36,000 seconds. The maximum lifetime configured for specific mobile nodes can override this lifetime value
- replaySeconds—Number of seconds, in the range 1–255, by which a registration request can exceed the home agent configured time value; default value is 7 seconds
- reverse-tunnel-off—Disables reverse tunneling support by the home agent, which denies T bit registration requests. By default, reverse tunneling is enabled on the router. When you modify support for reverse tunnels, the modification takes effect only for subsequently accepted registration requests
