Nick,
Of course, but the server condenses all of the paths it learns at the XP
to just one path per prefix learned at the XP, thus significantly
reducing the load on the router: now the router has several times fewer
paths to choose from and store in memory.
The amount of saving depends entirely on the average number of paths per
destination at the XP. Perhaps some empirical data in this area would help
to quantify the possible gain.
Yakov.
