These routers work well on the Ethernet interface when the OSPF network type is "broadcast". However, if R1 is changed to use the "endpoint-to-endpoint" network type on the G0/0 interface, then the problem arises. What will happen? The two routers would still be neighbors, but they would not be able to exchange their LSDBs, and R1 would no longer have any routes known to the OSPF, as shown in Example 11-16.242 Chapter 11 Troubleshooting IPv4 Routing ProtocolsExample 11-16 Mismatched OSPF Network Type Causes LSDB Exchange FailureRl# configure terminal Enter configuration commands, one perline. end with CNTL/Z. rl(config)# interfacegigabitethernetO/O Rl(config-if)# ip ospf network point-to-point Rl(config-if)# AZ Rl# Rl# showip route ospfCodes:L -local,C -connected,S -static,R -RIP,M -mobile,B -BGP D-EIGRP,EX -EIGRP external,0 -OSPF,IA -OSPFinter areaN1 OSPF NSSA external type 1, N2 -OSPF NSSA external type 2E1 OSPF external type 1, E2 -OSPF external type 2 i-IS-IS, su -IS-IS summary,LI -IS-ISlevel-1,L2 -IS-ISlevel-2 ia IS-ISinter area, *-candidatedefault ,U -per-userstaticrouteo-ODR,P -periodicdownloadedstaticroute,H -NHRP,1 -LISP +-replicated route, % -next hop overrideRl# 1 Lines omitted for brevityNote that in an active network, it is best to use the default OSPF network type unless it is necessary to modify these values. Chapter 14 gives a common example of how you can configure non-default values when using a particular style of Frame Relay configuration. Mismatched MTU Settings
