Proxy-Mobile IP
Configuring Proxy Mobile-IP Support ▀
Cisco ASR 5x00 Packet Data Network Gateway Administration Guide ▄
455
Notes:
The
proxy-mip max-retransmissions
command configures the maximum number re-try attempts that the
FA service is allowed to make when sending Proxy Mobile IP Registration Requests to the HA.
proxy-mip retransmission-timeout
configures the maximum amount of time allowed by the FA for a
response from the HA before re-sending a Proxy Mobile IP Registration Request message.
proxy-mip renew-percent-time
configures the amount of time that must pass prior to the FA sending a
Proxy Mobile IP Registration Renewal Request.
Example
If the advertisement registration lifetime configured for the FA service is 900 seconds and the renew-time is
configured to 50%, then the FA requests a lifetime of 900 seconds in the Proxy MIP registration request. If
the HA grants a lifetime of
600
seconds, then the FA sends the Proxy Mobile IP Registration Renewal
Request message after
300
seconds have passed.
Use the
fa-ha-spi remote-address
command to modify configured FA-HA SPIs to support Proxy Mobile
IP. Refer to the
Command Line Interface Reference
for the full command syntax.
Important:
Note that FA-HA SPIs
must
be configured for the Proxy-MIP feature to work,
while it is optional for regular MIP.
Use the
authentication mn-ha allow-noauth
command to configure the FA service to allow
communications from the HA without authenticating the HA.
Verify the FA Service Configuration
Use the following command to verify the configuration of the FA service:
show fa-service name
<
fa_service_name
>
Notes:
Repeat this example as needed to configure additional FA services to support Proxy-MIP.
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec
mode command
save configuration
. For additional information on how to verify and save configuration
files, refer to the
System Administration Guide
and the
Command Line Interface Reference
.
Proceed to the optional
Configuring Proxy MIP HA Failover
section to configure Proxy MIP HA Failover support or
skip to the
Configuring HA Services
section to configure HA service support for Proxy Mobile IP.
Configuring Proxy MIP HA Failover
Use this example to configure Proxy Mobile IP HA Failover:
Important:
This configuration in this section is optional.
When configured, Proxy MIP HA Failover provides a mechanism to use a specified alternate Home Agent for the
subscriber session when the primary HA is not available. Use the following configuration example to configure the
Proxy MIP HA Failover:
