IGP Commands
Default
The default tag number is 0. The default setting is disabled.
Usage Guidelines
After it is enabled, the OSPF router is considered to be an ASBR. Interface routes that correspond to the
interface that has OSPF enabled are ignored.
Exporting routes from OSPF to RIP, and from RIP to OSPF, are discrete configuration functions. To run
OSPF and RIP simultaneously, you must first configure both protocols and then verify the independent
operation of each. Then you can configure the routes to export from OSPF to RIP and the routes to
export from RIP to OSPF.
The cost metric is inserted for all RIP-learned, static an direct routes injected into OSPF. For “i” series
switches, the cost metric is also inserted for all BGP and VIP, injected into OSPF. If the cost metric is set
to 0, the cost is inserted from the route. The tag value is used only by special routing applications. Use 0
if you do not have specific requirements for using a tag. The tag value in this instance has no
relationship with 802.1Q VLAN tagging.
The same cost, type, and tag values can be inserted for all the export routes, or route maps can be used
for selective insertion. When a route map is associated with the export command, the route map is
applied on every exported route. The exported routes can also be filtered using route maps.
Example
The following command enables OSPF to export BGP-related routes using LSAs to other OSPF routers
on an
“i” series switch:
enable ospf export bgp cost 1 ase-type-1 tag 0
