AIS AI2524 Configure Ospf over Different Physical Networks, Ip ospf dead-interval seconds

Chapter 8: AI2524 Protocol Configuration Steps

6.Set the number of seconds that a device's hello packetsmust not have been seen before its neighbors declare the OSPF route down.

ip ospf dead-interval seconds

7.Assign a specific password to be used by neighboring OSPF rout- ers on a network segment that is using OSPF's simple password authentication.

ip ospf authentication-key key

8. Enable OSPF MD5 authentication.

ip ospf message-digest-key key id md5 key

Configure OSPF over Different Physical Networks

OSPF classifies different media into three types of networks by de fault:

zBroadcast networks (Ethernet, Token Ring, FDDI)

zNonbroadcast multi-access networks (SMDS, Frame Relay, X.25

zPoint-to-point networks (HDLC, PPP)

Configure your network as either a broadcast or a nonbroadcast multi- access network.

X.25 and Frame Relay provide an optional broadcast capability that can be configured in the map to allow OSPF to run as a broadcast net- work.
