Appendix B. The Abridged OSI Reference Model

Part II

Section IX: BGP Configuration

1. R1, R2, and R6 are in autonomous system 2010. R4 is in autonomous system 2020. The Backbone 1 router is in autonomous 2001. Configure an IBGP peer from R1 to R2 and from R2 to R6.

2. Configure an EBGP peer from R2 to R4. Configure an EBGP peer from R1 to the Backbone 1 router, 160.100.2.254, in autonomous system 2001.

3. Synchronize BGP with OSPF.

4. On R4 assign and advertise the 10's network through BGP.

5. Three subnets are being advertised from the backbone router: 192.190.100.0 to 192.190.102.0. Summarize the subnets into the supernet of 192.0.0.0/8. Advertise only this subnet and suppress all other routes.

Section X: DLSw Configuration

1. Configure a DLSw TCP peer between R3, Ring 1, and R5, VLAN 55. Configure another TCP peer from R3 to R1's Backbone 1.

2. Allow only NetBIOS reachability from Ring 1 to Backbone 1.

3. Configure R5 to advertise local reachability to a server called unnamed.

Section XI: Miscellaneous Cisco IOS Software Features

1. Configure R5 so that IP ping traffic from VLAN 55 destined toward VLAN 30 will take the ISDN link. All other IP traffic will take the frame circuit.

2. Configure R4 so that only SNA traffic to MAC address 3745.0001.0001 is allowed on Ring 2.

3. Configure R1 so that when the user unnamed logs into the router, that user immediately is put in enable mode.

4. Configure the access server so that the reverse Telnet sessions to the routers in the lab will never time out.
