It would be nice to be able to specify large numbers of confederation peers in a form other than an explicit list. For example, if you want to specify all the ASNs between 65280 through 65287, and 65296 through 65299, you currently need to specify:
/routing bgp instance set INSTANCE confederation-peers=65280,65281,65282,65283,65284,65285,65286,65287,65296,65297,65298,65299
It would be nice to be able to specify it as something like one of these, or both:
/routing bgp instance set INSTANCE confederation-peers=65280/13,64296/14
/routing bgp instance set INSTANCE confederation-peers=65280-65287,65296-65299
Not really a big deal with twelve sub-ases, but with hunderds it would be a huge help. In the not too distant future, with 32-bit asns, it would be especially helpful to be able to specify 1.0/16, and have that entire ‘reserved’ block treated as part of a confederation.
Just a thought,
