no site-min-down-timer
Context config>redundancy>bgp-multi-homing
Description This command configures the BGP multi-homing site minimum down time. When set to a non-zero
value, if the site goes operationally down it will remain operationally down for at least the length of
time configured for the site-min-down-timer, regardless of whether other state changes would have
caused it to go operationally up. This timer is restarted every time that the site transitions from up to
down.
The above operation is optimized in the following circumstances:
The no form of the command reverts to default value.
Default no site-min-down-timer
Parameters
min-down-time — Specifies the time, in seconds, that a BGP multi-homing site remains
synchronize
Syntax synchronize {boot-env | config}
no synchronize
Context admin>redundancy
Description This command performs a synchronization of the standby CPM's images and/or configuration files to
the active CPM. Either the boot-env or config parameter must be specified.
In the admin>redundancy context, this command performs a manually triggered standby CPM
synchronization. When the standby CPM takes over operation following a failure or reset of the active
CPM, it is important to ensure that the active and standby CPM have identical operational parameters.
This includes the saved configuration, CPM, XCM, and IOM images.
Basic System Configuration Guide
• If the site goes down on the designated forwarder but there are no BGP multi-homing peers
with the same site in an UP state, then the site-min-down-timer is not started and is not used.
• If the site goes down on the designated forwarder but there are no active BGP multi-homing
peers, then the site-min-down-timer is not started and is not used.
• If the site-min-down-timer is active and a BGP multi-homing update is received from the
designated forwarder indicating its site has gone down, the site-min-down-timer is
immediately terminated and this PE becomes the designated forwarder if the BGP multi-
homing algorithm determines it should be the designated forwarder.
operationally down after a transition from up to down.
