4. Configure Router B and Router C to redistribute BGP routes into OSPF:
# Configure OSPF to redistribute routes from BGP on Router B.
[RouterB] ospf
[RouterB-ospf-1] import-route bgp
# Configure OSPF to redistribute routes from BGP on Router C.
[RouterC] ospf
[RouterC-ospf-1] import-route bgp
# Display the routing table of Router A.
[RouterA] display ip routing-table

5. Configure summary route 10.0.0.0/8 on Router B and advertise it:
[RouterB-ospf-1] asbr-summary 10.0.0.0 8
# Display the routing table of Router A.
[RouterA] display ip routing-table
