Redistribute routes Add routes from other routing instances or protocols to the OSPFv2 process and include BGP, static, or connected routes in the OSPFv2 process. Do not route IBGP routes to OSPFv2 unless there are route-maps associated with the OSPFv2 redistribution. NOTE: With the redistribute static command in the running configuration, if a static route is configured which is also learned through OSPF, even if the static route preference is higher than OSPF, the static route is installed in the routing table. • Enter which routes redistribute into the OSPFv2 process in ROUTER-OSPF mode. redistribute {bgp as-number| connected | static} [route-map map-name] • bgp | connected | static-Enter a keyword to redistribute those routes. • route-map map-name-Enter the name of a configured route map.

Default route You can generate an external default route and distribute the default information to the OSPFv2 routing domain. • Generate the default route using the default-information originate [always] command in ROUTER-OSPF mode. Configure default route OS10(config)# router ospf 10 OS10(config-router-ospf-10)# default-information originate always View default route configuration OS10(config-router-ospf-10)# show configuration ! router ospf 10 default-information originate always Summary address You can configure a summary address for an ASBR to advertise one external route as an aggregate, for all redistributed routes that are covered by specified address range. • Configure the summary address in ROUTER-OSPF mode. summary-address ip-address/mask [not-advertise | tag tag-value] Configure summary address OS10(config)# router ospf 100 OS10(config-router-ospf-100)# summary-address 10.0.0.0/8 not-advertise View summary address OS10(config-router-ospf-100)# show configuration ! 618 Layer 3
