Here is something I just stumbled over and am a little puzzled by. Network
config is like ascii picture below...
R4
I
I
I
Frame----------------R2
I I
I vlan20
I I
R7 ------------------CAT5--------isl trunk------------R6
vlan70 I
vlan50
I
R5
R2/R4 and R7 are connected over the frame cloud and OSPF area 0 runs there
only. Vlans 20/50/70 are all trunked on R6 which performs router on a stick.
R4 has an ethernet LAN running OSPF area 2. OSPF area 3 runs on all the vlan
links between R2/R7/R5 and R6. Dilemma: R5 and R6 only have OSPF area 3
defined under their OSPF processes yet I can still see complete routes to all
other OSPF networks!! I am puzzled why I do not need a virtual link on R5 and
R6 to R2 or R7 see the other OSPF networks. I can ping any and all OSPF
networks from any and all routers. Anyone know why????
Cheers
