Either way, the routes are getting into the global table...does the end of the aspath matter that much?It adds zero useful data to the global table, but increases RAM, CPU, etc. on every router looking at the global table. Given how vociferously people argue against items in the table which _do_ add useful data, superfluous info should be avoided whenever possible. IMHO, of course.
In the past under these circumstances, if the customer still insists on BGP after I strongly recommeded just a static DFG, I'd peer with the customer with a private AS (64512-65535). Then they usually ask me to annouce a DFG to them. Sometimes they'd want a full table. Sigh. At least they'd have the future flexibility of adding another provider without much change. I've personally done that too. Chris
