i have 142 largish bgp customers, a large enough number that the number of prefixes i receive from them varies annoyingly. how do i reasonably automate setting of my outbound prefix limit?
First, it seems you know the inbound so automating the outbound is simple arithmetic.
I would have said the same... i ought to know high-water marks for your inbound peer count(s), and can work out a +20% outbound... you also probably can survey your outbound peerings and +20% some high-water mark there, or make a 'meet in the middle' between the inbound-math and outbound-math.
But even if that is unruly, setting the outbound to, say, 300K or so would keep you from spilling a full table. Not perfect, but better than nothing.
Orrrrrr, perhaps this feature is not for you?
