NOTE
The route map you specify must already be configured on the
device.
NOTE
If you use both the
redistribute ospf route-map
command and the
redistribute ospf match internal
command, the software
uses only the route map for filtering.
Redistributing static routes
To configure the device to redistribute static routes, enter the following command.
device(config-bgp)# redistribute static
Syntax:
[no] redistribute static
[
metric
num
] [
route-map
map-name
]
The
static
parameter indicates that you are redistributing static routes into BGP4.
The
metric
num
parameter changes the metric. You can specify a value from 0 - 4294967295. The default is 0.
The
route-map
map-name
parameter specifies a route map to be consulted before adding the static route to the BGP4 route table.
NOTE
The route map you specify must already be configured on the
device.
Redistributing IBGP routes
By default, the device does not allow redistribute IBGP routes from BGP4 into RIP, or OSPF. This behavior helps eliminate routing loops.
In non-default VRF instances, by default, the device does allow redistribution IBGP routes from BGP4 into RIP, OSPF.
To enable the device to redistribute BGP4 routes into OSPF and RIP, enter the following command.
device(config-bgp-router)# bgp-redistribute-internal
Syntax:
[no] bgp-redistribute-internal
To disable redistribution of IBGP routes into RIP, IS-IS, and OSPF, enter the
bgp-redistribute-internal
command.
