Load Balance CISCO 3640 w/ 3 T1's

[achilleus]

Thanks in advance for any help you have to offer!

I am new to the world of Cisco. I have a 3640 router with 3 T1s coming into it and 3 Fast Ethernets going out.

Here is my question: I want to load balance connections between the 3 T1s. How do I do this? As it stands now, one T1 will get 99.9% of the traffic. I want it to be semi even among the three of them. Is this possible?

Thanks again! AJ

lets see I think that you would be ok with mutilink. here is a sample.


Router A
interface Multilink1
ip address 192.168.1.26 255.255.255.252
no ip directed-broadcast
no ip mroute-cache
no cdp enabled
ppp multilink
no ppp multilink fragmentation
multilink-group 1

interface serial0/0
bandwidth 1544
no ip address
no ip directed-broadcast
encapsulation ppp
no ip mroute-cache
no fair-queue
ppp mutilink
multilink-group 1

interface serial0/1
bandwidth 1544
no ip address
no ip directed-broadcast
encapsulation ppp
no ip mroute-cache
no fair-queue
ppp mutilink
multilink-group 1

ip default-gateway 192.168.1.25

RouterB
interface multilink1
ip address 192.168.1.25 255.255.255.252
no cdp enabled
ppp multilink
no ppp multilink fragmentation
multilink-group 1

int serial0/0
bandwidth 1544
no ip address
encapslation ppp
no ip mroute-cache
no fair-queue
ppp multilink
multilink-group 1

int serial0/1
bandwidth 1544
no ip address
encapslation ppp
no ip mroute-cache
no fair-queue
ppp multilink
multilink-group 1

ip default-gateway 192.168.1.26

You can setup an ip route

ip route 0.0.0.0 0.0.0.0 multilink 1

try this and let me know.

if you are running ospf, then it will automatically load balance traffic thru all 3 lines. since the "cost" 9ospf metric) is same on all 3 lines, load balance is acheived automatically.
