• Changes in the neighbor state or interface state before or during a switchover do not take eect.
• Trac counters are not synchronized because the neighbor and LSA database counters are recalculated on the standby module
during synchronization.
• LSA acknowledging is delayed because it has to wait until standby acknowledging occurs.
• Depending on the sequence of redistribution or new LSAs (from neighbors), the LSAs accepted within the limits of the database
may change after switchover.
• In NSR hitless failover, after switchover, additional ooding-related protocol trac is generated to the directly connected
neighbors.
• OSPF startup timers, database overow, and max-metric, are not applied during NSR switchover.
• Brocade NetIron devices may generate OSPF log messages or OSPF neighbor timers are reset but these issues do not cause
any OSPF or trac disruption.
Disabling conguration
To disable the route-map parameter from the conguration, enter the following command:
device(config-ospf-router)# no default-information-originate route-map defaultToOspf
The above CLI would retain the conguration with default-information-originate alone and the route-map option would get reset or
removed.
The following commands with any or all of the options will remove the options from the default-information-originate command if any
of the options are congured:
device(config-ospf-router)# no default-information-originate always
device(config-ospf-router)# no default-information-originate always route-map test
device(config-ospf-router)# no default-information-originate always route-map test metric 200
device(config-ospf-router)# no default-information-originate always route-map test metric 200 metric-type
type1
In the following example, the parameters of the default-information-originate command are reset if they are
congured and if none of
the parameters are congured then, these commands will have no eect.
To disable the origination of default route, issue the command with no option and without any other options. This would remove the
conguration of the default information origination even if any of the above mentioned options are congured.
Syntax: [no] default-information-originate [ always ] [ metric metricvalue ] [ metric-type metric-type ] [ route-map rmap-name ]
The always parameter advertises the default route regardless of whether the router has a default route. This option is disabled by default.
The metric value parameter species a metric for the default route. If this option is not used, the default metric is used for the route.
The metric-type type parameter species the external link type associated with the default route advertised into the OSPF routing
domain. The type can be one of the following:
• type1 - Type 1 external route
• type2 - Type 2 external route
If you do not use this option, the default redistribution metric type is used for the route type.
