When running all daemons with config for most of them, FRR has sharpd@janelle:~/frr$ vtysh -c "show debug hashtable" | grep "VRF BIT HASH" | wc -l 3570 3570 hashes for bitmaps associated with the vrf. This is a very large number of hashes. Let's do two things: a) Reduce the created size of the actually created hashes to 2 instead of 32. b) Delay generation of the hash *until* a set operation happens. As that no hash directly implies a unset value if/when checked. This reduces the number of hashes to 61 in my setup for normal operation. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
