Hello!
I have cisco 3660 and 2801 connected over two serial lines and I use multippp. I have service-policy output on Multilink interfaces on both sides. But if I reload one of routes (like I did a hour ago) than service- policy on both routers disappears and router sets fair-queue on multilink interfaces. I think this is because service-policy I have can be appllied to multilink interface only when both serial interfaces are up otherwise there is no enough bandwidth.... How can I solve this without applying service-policy again and again? IOS version on both routers is 12.4.
