Actually, your t-1's will probably not be in the same subnet. They will probably have a /30 for each link. Additionally, you may consider adding no ip route-cache to each t1 interface. This will allow per-packet load balancing instead of per destination.

[7:33599] I have a configuration question. I have 3 dedicated T1's a router 3620 with three T1 CSU/DSU and one FastEthernet ports installed. All dedicated T's are from the same ISP. I want to aggregate the three T1's for increased bandwidth (4.5 Mbps) Would I run into issues Here is my config. Would this work? ! hostname Cisco3620 ! ! no ip name-server ! ip subnet-zero no ip domain-lookup ip routing ! interface Ethernet 0/0 no description ip address 172.16.10.1 255.255.255.0 ! interface Serial 0/0 no shutdown ip address 1.1.1.2 255.255.255.248 ! interface Serial 0/1 no shutdown ip address 1.1.1.3 255.255.255.248 ! interface Serial 1/0 no shutdown ip address 1.1.1.4 255.255.255.248 ! ip route 0.0.0.0 0.0.0.0 serial0/0 ip route 0.0.0.0 0.0.0.0 serial0/1 ip route 0.0.0.0 0.0.0.0 serial1/0 ! ! ip classless no ip http server ! end I tried this config with Cisco's config maker and I get IP address errors on the serial ports, specifically being on the same subnet. Would this do basic aggregation?
