Routes Lab 01 - WAN OSPF area 0

We could use a few type of frame-relay network (NBMA or point-to-multipoint). Let's go with point-to-multipoint, it's like a collection of point-to-point network from each sites. This is not going to be a Hub and Spokes network because each site have it's own DLCI to others. So it's a full mesh network.

Add below command on all WAN interfaces to make a point-to-multipoint Frame-relay network.

interface Serial0/1
 ip ospf network point-to-multipoint

configure OSPF area 0 for the WAN interfaces and Loopbacks, do the same for the rest of the Net

router ospf 1
 network area 0

 network area 0

make sure neighbor are formed between the three WAN routers. below are a few useful command to get some information and troubleshoot.

show ip route
show ip route ospf
sh ip ospf interface serial 0/1
show ip protocols
show ip ospf
show ip ospf neighbor

next we will configure routing on the LAN using EIGRP and redistribute it to the OSPF so that the other side of the network can reach it.
