Hello, I am starting to play with OSPF in GNS3 and I cannot get my routes to summarize in the routing tables of R1 and R2. The routing tables are as follows: R1#sh ip route Gateway of last resort is not set 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback10 10.0.0.0/8 is variably subnetted, 10 subnets, 2 masks O 10.2.10.0/24 [110/20] via 10.0.0.6, 00:18:04, FastEthernet0/1 C 10.1.3.0/24 is directly connected, Loopback3 C 10.1.2.0/24 is directly connected, Loopback2 C 10.1.1.0/24 is directly connected, Loopback1 C 10.0.0.0/30 is directly connected, FastEthernet0/0 C 10.0.0.4/30 is directly connected, FastEthernet0/1 C 10.1.4.0/24 is directly connected, Loopback4 O 10.2.30.0/24 [110/20] via 10.0.0.6, 00:18:05, FastEthernet0/1 O 10.2.20.0/24 [110/20] via 10.0.0.6, 00:18:05, FastEthernet0/1 O 10.2.40.0/24 [110/20] via 10.0.0.6, 00:18:05, FastEthernet0/1 R1# --------------------------------------------------------------------------------------------------------------- R2#sh ip route Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 10 subnets, 3 masks C 10.2.10.0/24 is directly connected, FastEthernet0/1.10 O 10.1.2.1/32 [110/11] via 10.0.0.5, 06:05:30, FastEthernet0/0 O 10.1.3.1/32 [110/11] via 10.0.0.5, 06:05:30, FastEthernet0/0 O 10.0.0.0/30 [110/20] via 10.0.0.5, 06:05:30, FastEthernet0/0 O 10.1.1.1/32 [110/11] via 10.0.0.5, 06:05:30, FastEthernet0/0 O 10.1.4.1/32 [110/11] via 10.0.0.5, 06:05:30, FastEthernet0/0 C 10.0.0.4/30 is directly connected, FastEthernet0/0 C 10.2.30.0/24 is directly connected, FastEthernet0/1.30 C 10.2.20.0/24 is directly connected, FastEthernet0/1.20 C 10.2.40.0/24 is directly connected, FastEthernet0/1.40 R2# I have put in summary addresses in the configs of both routers (attached) but R1's routing table won't summarize the 10.2.x.x networks and R2 won't summarize the 10.1.x.x networks. Am I doing something wrong? Thanks in advance Matt
