Hi,
I was researching on Nexus 3000 routing scale and came across the option to enable ALPM mode that can support up to 128K IPv4 prefix or 80k IPv6 prefix in LPM table. Taking a further look, i see that by enabling "system routing max-mode l3" and disabling "urpf" i could see increase in available scale but It also means that switch will not support IPv6 route with prefix length between /65-/127 unless we use IPv6 carving option - Max Ucast IPv6 LPM_65_to_127 Limit Entries = 0
Does it mean that I can't even use /126 IPv6 on P2P link between Spine and leaf if I'm using L3 CLOS architecture and not advertising P2P link prefix through any routing protocol like BGP or so ?
Thanks,
Chintan
