Well, when I've done practices, I have done many scenarios where I set
priority of 100 on the hub on the int. and 'neigh xxx prior 1' under router
ospf config, and 'neigh xxx' under the spoke router config, the neighbor
association would take place (although slow to initialize) and naturally
since you are doing this using a routing protocol, the spokes could
communicate. Now if you weren't using ospf, it would be a different issue
altogether. But this will definately fill his criteria of needing
reachibility btwn. the routers without using map statements.
Am I misunderstanding the situation?
ex:
r2 (hub)
router ospf 1
log-adjacency-changes
network 135.1.2.0 0.0.0.255 area 1
network 135.1.7.0 0.0.0.31 area 1
network 135.1.22.0 0.0.0.63 area 2
network 135.1.28.0 0.0.3.255 area 0
neighbor 135.1.7.5 priority 1
neighbor 135.1.7.1 priority 1
interface Serial0
ip address 135.1.7.2 255.255.255.240
ip ospf priority 100
r5 (spoke)
router ospf 1
network 135.1.1.0 0.0.0.255 area 1
network 135.1.7.0 0.0.0.15 area 1
neighbor 135.1.7.2 priority 100
default-metric 64
r1 (spoke)
router ospf 1
network 135.1.1.0 0.0.0.255 area 1
network 135.1.7.0 0.0.0.15 area 1
neighbor 135.1.7.2 priority 100
default-metric 64
