Appendix E

IP/OSPF Configuration Example

The IP/OSPF configuration in Figure E-1 shows an AS divided into different

types of OSPF areas using several types of OSPF routers and interfaces as well as

variable-length subnetting. This appendix describes parameter settings for router 1

through router 6. Routers W through Z and A through D are included in the figure

to complete the network map.

In the configuration in Figure E-1

• The OSPF Area Authentication parameter is set to none for all areas.

• All timer parameters (Hello, dead, and poll interval) are set to their default

values.

• No virtual links are configured.

• Route summarization is not used.

• The frame relay cloud is set to the default management type. It is non-fully

meshed with all group mode PVCs.

• There are three area border routers (router 2, router 3, and router 4), two

internal backbone routers (router 1 and router 5) and one AS boundary router

(router 6 has an Ethernet interface using RIP).

• Router 2 is the designated router for the FDDI segment. Router 4 must be the

designated router for the frame relay cloud.

• The unnumbered LAN connecting router 6 and router D is included to ensure

that every internal node in area 0.0.0.1 is reachable from every other internal

node.
