Redistributing Routes into IS-IS
Each routing protocol uses different metrics to transfer routes. Some protocols use
hop count metrics, while others use bandwidth and delay attributes to define metrics.
When a specific route is redistributed from one routing protocol or domain into
another, a common metric must be applied by the receiving protocol. Routes are
redistributed to advertise networks on another routing protocol.
Follow these steps to redistribute routes into IS-IS:
1. Enter the IS-IS routing process in which the routes are to be redistributed, as
shown below:
MOT(config)#router isis
2. Choose from one or more of the following options to redistribute routes from a
specified protocol:
• Use the redistribute ospf command in Router Configuration mode to
redistribute OSPF routes into IS-IS, as shown below:
MOT(config-isis)#redistribute ospf {[external | internal] | metric
<n> | metric-type [external | internal] | route-map <map-name> | <cr>}
where:
The external argument is used to redistribute external OSPF routes.
The internal argument is used to redistribute internal OSPF routes.
metric <n> is the redistribution metric number for OSPF routes.
The metric-type external argument is used to redistribute external IS-IS
metric-type.
The metric-type-internal argument is used to redistribute internal IS-IS
metric-type.
route-map <map-name> is the OSPF route-map name.
cr is a command return that redistributes of all OSPF routes.
• Use the redistribute connected command in Router Configuration mode to
redistribute connected routes into IS-IS, as shown below:
