NETGEAR 8800 Chassis Switch CLI Manual Syntax Description blackhole direct ospf ospf-extern1 ospf-extern2 ospf-inter ospf-intra rip static address-family Specifies blackhole routes. Specifies direct routes. Specifies OSPF routes. Specifies OSPF-extern1 routes. Specifies OSPF-extern2 routes. Specifies OSPF-inter routes. Specifies OSPF-intra routes. Specifies RIP routes. Specifies static routes. The address family to which the IGP routes is exported. BGP supports two address families: IPv4 Unicast and IPv4 Multicast. Default Disabled. If no address family is specified, IPv4 unicast is the default. Usage Guidelines The exporting of routes between any two routing protocols is a discrete configuration function. For example, you must configure the switch to export routes from OSPF to BGP and, if desired, you must configure the switch to export routes from BGP to OSPF. 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 BGP, and the routes to export from BGP to OSPF. Similarly for BGP and RIP. You can use policies to associate BGP attributes including Community, NextHop, MED, Origin, and Local Preference with the routes. Policies can also be used to filter out exported routes. Using the export command to redistribute routes complements the redistribution of routes using the configure bgp add network command. The configure bgp add network command adds the route to BGP only if the route is present in the routing table. The enable bgp export command redistributes an individual route from the routing table to BGP. If you use both commands to redistribute routes, the routes redistributed using the network command take precedence over routes redistributed using the export command. Example The following command disables BGP from exporting routes from the OSPF protocol to BGP peers: 1128 | Chapter 25. BGP Commands
