[j-nsp] load balance traffic

[sunnyday]

Hello I have a j router with 2 adsl cards  they have been assigned ip
address from the bras.

 

pp0.0                   up    up   inet     10.11.11.7          --> 1.1.1.1

pp0.1                   up    up   inet     10.11.11.8          --> 1.1.1.1

 

 

the problem is that only one adsl card(pp0.1) can ping the loopback(1.1.1.1)
of the bras:

1.1.1.1/32         *[Direct/0] 00:23:33

                    > via pp0.1

                    [Direct/0] 00:23:33

                    > via pp0.0

 

10.11.11.7/32      *[Local/0] 00:27:34

                      Local via pp0.0

10.11.11.8/32      *[Local/0] 00:27:34

                      Local via pp0.1

Any ideas on how to change the behavior and have both interfaces forwarding
for the gateway?
