Posted on by

Configure the routers therefore each router will be able to ping others using the following information:

  • Each router connected using point-to-point network link.
  • Serial link on Router 3 (R3) to Router 4 (R4) is DTE-DCE.
  • Use only OSPF routing protocol.
  • Each OSPF process should use Router number (Eg. Router 1 (R1) has OSPF process ID 1).
  • Do not use Loopback interface.
  • Use specific Router ID using address 20.20.20.<Router number> (Eg. Router 1 (R1) has Router ID 20.20.20.1).
  • Do not involve any Designated Router (DR).
  • Do not use dynamic layer 3 to layer 2 mapping on any of these frame relay connections, instead, use static mapping.
  • Frame relay link between R3 and R4 is provided as backup link. Use the Serial link as primary link. Do not use backup interface command to accomplish this.
  • Router 4 (R4) should not receive ospf summary and external updates from Router 3 (R3).
  • Routing in Router 4 (R4) should appear as follows: 
         10.0.0.0/30 is subnetted, 2 subnets
C       10.10.10.8 is directly connected, Serial0.1
C       10.10.10.12 is directly connected, Serial1
O*IA 0.0.0.0/0 [110/74] via 10.10.10.13, 00:00:36, Serial1

Routers configuration will be provided tomorrow, 30 May 2006
