2 adsl dialers on the same router

Unanswered Question
Feb 20th, 2007

hey,

i have 2 adsl lines i need to connect to 1 router. i can't change the pvc number or take 1 big line. i also need to have load sharing between the lines.

so far i did so by 2 vrfs - only way the lines work together, because of the same pvc as far as i know. i ran bgp and then i could route between the vrfs, but i can't ping to the dialer if it's in different vrf.

can someone help? thanks.

I have this problem too.

the configuration is followed, the diagram is attached.

the weird thing is i can route between different vrfs except for the dialer, which can be reached only from the same vrf.
