Hi All
I have HUB and Spoke Topology with default ospf network type (NON_BROADCAST).
R2 --- HUB (DR)
R5 --- Spoke (DRother)
R6 --- Spoke (DRother)
I am using ip ospf network non_broadcast (default type) on all routers
Problem # 1
***********
I tried to put "neighbor command" on my Spokes. Router accepts
it and then command vanishes from Configuration?? Any clue??
IOS (tm) 2500 Software (C2500-IS-L), Version 12.0(9),
Problem # 2
************
Router 5 shows up 2nd neighbor (Spoke) in Attempt STATE
R5-Spoke-2509#sh ip os ne
Neighbor ID Pri State Dead Time Address Interface
200.0.0.2 255 FULL/DR 00:01:58 150.50.100.2 Serial0 <---
this is R2 (HUB)
N/A 0 ATTEMPT/DROTHER - 150.50.100.6 Serial0
<===== problem!!
Why is the other spoke (r6) showing up here in R5 neighbor???
