Configuring Support for Opaque LSAs
The RS supports opaque LSAs as defined in RFC 2370. This ability is turned off by default because it can enlarge the
link state database unnecessarily.
To turn on support for RFC 2370 opaque LSAs, enter the following command in Configure mode:
Setting Route Preference
Preference is the value the RS routing process uses to determine the order of routes to the same destination in a single
routing database. The active route is chosen by the lowest preference value.
A default preference is assigned to each source from which the RS routing process receives routes. The default
preference value for OSPF routes is 10. You can change the default preference by entering the following command in
Configure mode:
For additional information on how the RS uses preference values, refer to Chapter 18, "Routing Policy Configuration" .
Setting the Reference Bandwidth
The RS uses the reference bandwidth to calculate the cost of an OSPF interface. The default reference bandwidth is
1000. You can change this value by entering the following command in Configure mode:
Specifies how many ASEs will be
generated and flooded in each batch.
The default is 250.
ospf set export-limit
<num>
Specifies AS external link
advertisement default parameters.
ospf set ase-defaults [preference
<num>

[cost
<num>

Enables the processing of opaque
LSAs on the RS.
