It is based on the introduction of nexthops - objects holding all necessary state to pass a packet to the desired destination. gitref:a666325282ea[repository=src] + Multipath routing support has been rewritten in more scalable fashion, featuring 64-wide multipath routes with O(1) lookup time. gitref:fedeb08b6a58[repository=src]. The `RADIX_MPATH` kernel option got replaced with `ROUTE_MPATH`, which is turned on by default. Additionally, the `net.route.multipath` sysctl has been added to control the feature in runtime. gitref:d1d941c5b910[repository=src], gitref:d5fe384b4d41[repository=src] + Support for custom route lookup algorithms has been added. The framework decouples control-plane and data-plane, resulting in both faster lookups and better convergence times for large tables under load. gitref:f5baf8bb12f3[repository=src] + DPDK librte-based IPv4/IPv6 route lookup algorithms has been added, optimising control-plane and data-plane for large routing tables. gitref:537d13437314[repository=src] Interface fib is now used for proxyarp checks. gitref:66bc03d41566[repository=src] + Loopback route installation has been fixed for the interfaces in different fibs using the same prefix. gitref:9fdbf7eef5c0[repository=src] + Number of fibs can now be changed at runtime by controlling `net.fibs` sysctl. gitref:f5247a232a33[repository=src] + `net.add_addr_allfibs` sysctl default has been changed to 0. gitref:2d3982419593[repository=src] Temporal routes (routes with `-expire` time set) expiration have been for both IPv4 and IPv6. gitref:34a5582c47c7[repository=src] + Duplicate routes installation issue for /32 or /128 interface aliases has been fixed. gitref:81728a538d24[repository=src] + IPv6 interface routes are now marked with RTF_PINNED like their IPv4 counterparts. gitref:81728a538d24[repository=src] + The {{< manpage "route" "8">}} network auto-guessing has been eliminated by removing remnants of classful behavior. gitref:d28210b2c2aa[repository=src] + Sysctl `net.inet6.ip6.deembed_scopeid` , making it possible to disable IPv6 scope de-embedding, has been removed. gitref:bec053ffe01d[repository=src] [[hardware]]
