redirect
: This option enables a redirect policy for overloading conditions. When a redirect policy is
invoked, the PDSN service rejects new sessions with an A11 Registration Reply Code of 88H (unknown
PDSN address) and provides the IP address of an alternate PDSN. This command can be issued multiple
times.
PDSN address) and provides the IP address of an alternate PDSN. This command can be issued multiple
times.
address
: The IP address of an alternate PDSN expressed in IP v4 dotted decimal notation. Up to 16 IP
addresses can be specified either in one command or by issuing the redirect command multiple times. If you
try to add more than 16 IP addresses to the redirect policy the CLI issues an error message. If you specify an
IP address and weight that already exists in the redirect policy the new values override the existing values.

weight_num
: When multiple addresses are specified, they are selected in a weighted round-robin
scheme. Entries with higher weights are more likely to be chosen. If a weight is not specified the entry is
automatically assigned a weight of 1.

weight_num
must be an integer from 1 through 10.
restricted
: This is an optional keyword which means the zone is restricted. Restricted zone is meaningful
only if enhanced PCF redirection feature is enabled, otherwise the zone follows the default behavior.
policy
rrq
mei-from-current-pcf
suppress-ppp-restart
rrq
configures policy for PPP restart after getting mei in rrq.
mei-from-current-pcf
mei is received in rrq from current pcf.
suppress-ppp-restart
suppresses ppp restart when mei is received in rrq from current pcf
policy
service-option
enforce
service-option
configures R-P service-option to use for specific PDSN service. Must be followed by
valid service-option number, ranging from 0 to 1000.
enforce
designates enforcement of R-P service-option number.
policy
unknown-cvse
enforce
unknown-cvse
configures PDSN service unknown cvse policy.
enforce
enforces unknown cvse policy where unknown CVSEs in RRQs will cause Deny
Usage
Policies can be implemented to dictate PDSN service behavior for various conditions such as overloading.
The system invokes the overload policy if the number of calls currently being processed exceeds the licensed
limit for the maximum number of sessions supported by the system.
The system automatically invokes the overload policy when an on-line software upgrade is started.

after deleting the policy setting you desire to return the policy parameter to its default setting, use the

command.
The chassis is shipped from the factory with the policy options set as follows:
overload disabled
sequence-numbers enforced enabled

Incorrect configuration of the

keywords
could result in sessions failing to be established. For example, if PDSN1 is configured to redirect sessions to PDSN2
while PDSN2 is configured to redirect sessions to PDSN1, a loop is created in which all sessions would fail to be
connected. In addition, sessions will not be established if the PDSN to which the sessions are being redirected is
unavailable.
