hi,
i've just implemented fib compression based on the following two ideas:
-two consecutive prefixes with the same nexthop...
-subnets of a supernet with the same nexthop...
it reduced the niif v6 fib from 160968 to 72298 (44%) and the v4 fib from
901199 to482847 (53%)
for the
https://bitbucket.software.geant.org/projects/RARE/repos/rare/browse/profiles/9.10.0/tofino2/profile-rawip.p4
profile we have a plenty of headroom for v6 and some headroom for v4...
for now only show commands are there but nothing holds back from adding
auto-summary knob
to the routing protocols and/or export-compress knob to the p4lang server...
or both...:)
br,
cs
