Filter the LSA-topology of Type 3 on the abr in the ospf Environment
LSA-requirement for filtering Type 3 in the OSPF Environment
Start OSPF on two routers, and make the frame relay interface participate in Area 0. Add three loopback interfaces on each router, loop0, loop1, and loop2, three loopback interfaces of R1 participate in ospf region 1, and three loopback interfaces of R2 participate in ospf Region 2.
