Gurus,
Pls do enlighten me on this:
A simple hub and spoke topology on FR.
2 spokes R3 and R4 and a hub router R1. I have a common prefix say 13.13.6.6 which is being redistributed in via R3 and R4 towards R1 over OSPF.
Case1:
router ospf 10
redistribute eigrp 10 subnets
R1 get the prefix and does not load balances via R3 and R4 , even after i check all the path metrics and forward metric were exactly same from both R3 and R4.
13.0.0.0/8 is variably subnetted, 10 subnets, 2 masks
O E2 13.13.6.6/32 [110/20] via 13.13.11.4, 00:00:10, Serial2/0
R1#sh ip route 13.13.6.6
Routing entry for 13.13.6.6/32
Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric 64
Last update from 13.13.11.4 on Serial2/0, 00:01:15 ago
Routing Descriptor Blocks:
* 13.13.11.4, from 13.13.4.4, 00:01:15 ago, via Serial2/0
Route metric is 20, traffic share count is 1
"failover to R3" , shutting the S2/0 of R4.
13.0.0.0/8 is variably subnetted, 11 subnets, 2 masks
O E2 13.13.6.6/32 [110/20] via 13.13.11.3, 00:00:03, Serial2/0
R1#sh ip route 13.13.6.6
Routing entry for 13.13.6.6/32
Known via "ospf 1", distance 110, metric 20, type extern 2, forward metric 64
Last update from 13.13.11.3 on Serial2/0, 00:00:02 ago
Routing Descriptor Blocks:
* 3.3.11.3, from 3.3.3.3, 00:00:02 ago, via Serial2/0
Route metric is 20, traffic share count is 1
Case2:
router ospf 10
redistribute eigrp 10 metric 20 subnets
in this case , R1 shows me prefix X via both R3 and R4.
13.0.0.0/8 is variably subnetted, 11 subnets, 2 masks
O E2 13.13.6.6/32 [110/20] via 13.13.11.4, 00:00:26, Serial2/0
[110/20] via 13.13.11.3, 00:00:26, Serial2/0
Seems im missing something.
do advise.
Thanx
Shukla.
