Hi, everyone.

While going through ccbootcamp lab 7, I found something very stange.

I am doing mutual redistribution on R2 and R6 without AD manipulation, I assume
 R3 should see
two equal cost routes about 10.51.0.0/16, one through R2, the other through R6,
 in fact R3 is
using only R2. If you shutdown the E0 interface of R2, it will use R6, when you
 bring R2's E0
back up, R3 is still using the R6 path.

R3's route table:
--------------------------
O IA 10.6.0.0/16 [110/74] via 10.100.1.6, 00:21:04, Serial0.1
O E2 10.21.0.0/16 [110/20] via 10.101.1.2, 00:21:04, Serial0.2
O E2 10.51.0.0/16 [110/20] via 10.101.1.2, 00:16:40, Serial0.2
O E2 10.65.0.0/16 [110/20] via 10.100.1.6, 00:21:04, Serial0.1
--------------------------
........

R2's configuration:
--------------------------
router ospf 1
 redistribute rip subnets
 network 10.101.0.0 0.0.255.255 area 0
 network 137.20.20.0 0.0.0.255 area 2
 default-information originate metric 200 metric-type 1
!
router rip
 redistribute ospf 1 metric 10
 passive-interface Ethernet0
 passive-interface Serial0
 network 10.0.0.0
---------------------------

R6's configuatioin:
--------------------------
router ospf 1
 redistribute rip subnets
 network 10.6.1.1 0.0.0.0 area 6
 network 10.100.0.0 0.0.255.255 area 0
!
router rip
 redistribute ospf 1 metric 10
 passive-interface Ethernet0
 passive-interface Serial0
 network 10.0.0.0
--------------------------

Can anybody shed some light on this ? TIA.

Best Rdgs.
