OSPF Posts: Frame Relay OSPF-radio host

Objectives:

In R1, R4 and R5's Frame Relay network configuration between the OSPF, the network type is broadcast, to achieve VLAN A, VLAN B and VLAN C interoperability






Configuration Guide:

Configured on the R1 interface, Ethernet0 / 0 address is 1.0.0.1 / 8

In the R4 on the configuration interface Ethernet0 / 0 address is 4.0.0.4 / 8

In R5 the configuration interface Ethernet0 / 0 address is 5.0.0.5 / 8

Configuration interface on the R1 Seria0 / 0 address is 10.0.0.1 / 8

In the R4 on the configuration interface Serial0 / 0 address is 10.0.0.4 / 8

Configuration interface on the R5 Serial0 / 0 address is 10.0.0.5 / 8

In R1, R4 and R5 of the Serial interface configuration Frame Relay encapsulation

R4 and R5 in the Reverse Address Resolution disable Frame Relay

Configure a static mapping in the R1 through DCLI104 to 10.0.0.4 and 10.0.0.5 through DLCI105 to

Configure a static mapping in the R4, to the 10.0.0.1 and 10.0.0.5 through DLCI401

Configure a static mapping in the R5, to the 10.0.0.1 and 10.0.0.4 through DLCI501

Ensure that the link supports broadcast and multicast packet delivery

In R1, R4, and R5 of the Serial interface configured OSPF network type as broadcast

R4 and R5 in the Serial Interface Configuration OSPF priority to 0

Configure R1, R4 and R5 join all the interfaces area 0

Self-question:

broadcast type of network and other network types are different?

This network type is a unicast or multicast LSA to send?

This type of network support for DR / BDR election?

These attributes have any effect on the configuration?

Final configuration and validation:

Notes:

Type in the network broadcast network OSPF hellos packets through multicast transmission, such as non-broadcast network type as required DR / BDR election. For Ethernet or Token Ring type network that broadcast, this is the default network type. Note that in this example framerelay map command to increase the broadcast option, because the hello packet is a multicast transmission. In addition, since not a single broadcast is why the DR and BDR do not need to configure the neighbor command. Similarly, there will be a precedent referred to the priority allocation problem, skip.

By using the show ip ospf neighbor command to verify that the neighbor relationship between the use of show ip ospf interface command to verify the network type and DR / BDR.

Next hop of the problem on a similar precedent.
