Importing BGP routes into OSPF
With this enhancement you can import routes from BGP into OSPF. OSPF will
then redistribute these routes. This enhancement adds three parameters to the
set ospf command, and modifies the output of the show ospf command. The
new parameters are bgpimport, bgpfilter and bgplimit.
BGP can learn thousands of routes, so it’s important to consider the network
impact of importing these routes. Routing devices in the OSPF domain may
become overloaded if they store too many routes. You can prevent this by
limiting the number of routes that will be imported.
Do not enable the importing of BGP routes into OSPF unless you are sure about
the consequences for the OSPF domain.
Enabling BGP route import
To enable importing BGP routes into OSPF, use the command:
set ospf bgpimport=on
Limiting the number of routes
There are two ways to limit the number of BGP routes imported into OSPF.
One way is to specify a maximum number of routes with the command:
set ospf bgplimit=1...300
When the limit is reached, the importing of routes will stop until existing
routes are removed. Because they are BGP routes, actions of BGP control when
the routes disappear.
