I need to summarize routes from the backbone area to connected areas!
The line in the config of the ABR looks like:
router ospf 2
area 0 range 10.4.0.0 255.255.0.0
area 1 range 10.2.0.0 255.255.0.0
The routing table on a router in area 1 looks like this:
d7-2610xm-TelAnl#sh ip route os
188.8.131.52/24 is subnetted, 1 subnets
O IA 184.108.40.206 [110/11] via 220.127.116.11, 00:18:31, FastEthernet0/0
10.0.0.0/32 is subnetted, 2 subnets
O IA 10.4.1.1 [110/12] via 18.104.22.168, 00:18:31, FastEthernet0/0
No summary 10.4.0.0/16
Is summarization only supported from an area to backbone area?
I found some examples in the net from cisco training sites, which show that summary should als work from backbone area to outside!
