I've private AS connected to other private AS's via 2 routers. I received route at first router with as-path 3 and on the second with as-path 4(i've made it for influence traffic). But during redistribution to OSPF all as-path information will be lost. How to preserve that info and use it later in OSPF domain for managing routes?
Ah well, you never said you wanted to do anything with them :)
If you want to set metrics you are better doing it when you redistribute - on the 7200 in our example. So you still use the as-paths to identify the relevant routes but then just set the metric you need.
