OSPF
Enable or disable the exporting of RIP, static, and direct (interface) routes to OSPF, using
the following commands:
enable ospf export [static | rip | direct] cost <metric> [ase-type-1 |
ase-type-2] {tag <number>}
disable ospf export [static | rip | direct]
These commands enable or disable the exporting of RIP, static, and direct routes by way
of LSA to other OSPF routers as AS-external type 1 or type 2 routes. The default setting
is disabled.
The cost metric is inserted for all RIP-learned, static, and direct routes injected into
OSPF. If the cost metric is set to zero, the cost is inserted from the route. The tag value
is used only by special routing applications. Use the number zero 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.
Enable or disable the export of Virtual IP addresses to other OSPF routers, using the
following commands:
enable ospf export vip cost <metric> [ase-type-1 | ase-type-2] {tag
<number>}
disable ospf export vip
Verify the configuration using the command:

ISTRIBUTION
When re-distributing RIP routes you should turn off RIP aggregation unless you are
expertly familiar with the possible consequences and impact. By default, new
configurations of RIP using ExtremeWare 4.0 and above disable RIP aggregation. In
previous ExtremeWare versions, RIP aggregation is enabled by default. This
configuration is preserved when upgrading to ExtremeWare 4.0. Verify the configuration
using the command
show rip
.
