Hi Konrad,
As of 18.01 the amount of memory available for IP routes is controlled in the
startup config with:
ip {heap-size <value>}
/neale

Subject: [vpp-dev] adding large number of route prefixes
Hi,
While testing ipv4 routing I found that vpp crashes when supplied with
large sets of prefixes, the exact point when vpp goes down changes
depending on prefix set and vpp version tested.
Tried 17.10 and 18.01, first consistently crashes at around 1m (though
tested only with sequential /24 and /32 prefixes), for the latter it
depends on the set, for sequential it's around 390k, while public bgp
table does crash pretty randomly around 100-300k, (my file has around 750k
routes).
For 17.10, adding less than 1m prefixes works for both scenarios and
continues working - adding and deleting it multiple times does not cause
any stability issues.
It doesn't seem dependent on heap-size parameter value.
I used both cli "ip route add count" as well as modified router plugin to
pull the table from netlink.
Any suggestions are welcome.
