New to most of this but couldn't you just salt the hashes being used per-router?

- bogomipz 8y agoYeah I think you could seed each router's hashing with something unique like a mac address hardware ID but you could also just use different hashing at each tier in your network like using source IP + dest IP on one tier and source IP + dest IP + IP protocol on another tier. This should achieve the same result.
- alecbenzer 8y agoYeah but then you need to keep coming up with new ways of hashing things as you add tiers. It's easier to generate a new salt than it is to figure out a new but still-valid way of hashing the packets.
- bogomipz 8y agoPractically speaking this isn't an issue though. You don't see many spine and leaf networks that are deeper than 3 tiers(edge, distribution, ToR) which means one link upstream and one down. It's not like people build networks arbitrarily deep.
