handoff
: Default: Enabled

MIP session occurs. If this is disabled, the HA is never triggered to send a Revocation message.
idle-timeout
: Default: Enabled

Usage

feature. Both the HA and the FA must have Registration Revocation enabled and FA/HA authorization must
be in use for Registration Revocation to be negotiated successfully.
Example
The following command enables Registration Revocation on the HA:
revocation enable
The following command sets the maximum number of retries for a Revocation message to
10
:
revocation max-retransmission 10
The following command sets the timeout between retransmissions to
3
:
revocation retransmission-timeout 3
The behavior of send MIP revocation to FA is as follows:
1st retry: Retransmit in 3 seconds after previous MIP revocation send.
2nd retry: Retransmit in 6 seconds after previous MIP revocation send (9 seconds after sending initial
MIP revocation).
3rd retry: Retransmit in 12 seconds after previous MIP revocation send (21 seconds after sending initial
MIP revocation).
4th retry: Retransmit in 24 seconds after previous MIP revocation send (45 seconds after sending initial
MIP revocation).
5th retry: Retransmit in 48 seconds after previous MIP revocation send (93 seconds after sending initial
MIP revocation).
Important:
The value of retransmission-timeout doubles. HA disconnects the session forcibly in 120 seconds
after sending initial MIP revocation.
