Multi-domain configuration of OSPF-OSPF + RIP

Configuration process on R1: 1. Allocate IP addresses to the Loopback 0 interface. 2. Assign IP3. to ethernet 0/0 to allocate IP addresses to interfaces S1/0 and encapsulate the PPP protocol.

Configure area 51 as The NSSA region on R2: 1. assign an IP address to the Loopback 0 interface. 2. Assign IP3. enable the OSPF routing protocol to the ethernet 0/0 interface. The process number is 110 and the network segment is directly connected. On R3: 1. assign an IP address to the S1/1 interface and encapsulate the PPP protocol 2. assign IP3. enable OSPF routing protocol to E0/0 interface. The process number is 110 and the network segment is directly connected.

Configure area 51 as The NSSA region and re-distribute the RIP route information. 5. enable the RIP Routing Protocol, declare the direct connection CIDR block, and re-distribute the OSPF route information on R4. assign IP2. enable the RIP Protocol to the E0/0 interface, advertise the direct connection network segment, and re-distribute the OSPF route information for experimental verification on R1: 1. on R1, view the OSPF neighbor and neighbor relationship. 2. view the route table on R1. 3. show ip protocols on R1 on R2: 1. View OSPF neighbor and Neighbor Relationship on R2. 2. view the route table in R2. 3. In R2show ip protocols on R3 1. In R3, view the OSPF neighbor and neighbor relationship. 2. view the route table on R3.
