default route distance filter

I’m using a simple routing filter to change the default route distance to 3 but this seems to capture all routes received as everything fits in 0.0.0.0/0 how would I exactly match this instead of everything in 0.0.0.0/0

if (dst in 0.0.0.0/0) {set distance 3; append comment LTE; accept}
else {reject}

dst == 0.0.0.0/0

Thanks I new it would be simple just couldn’t find it anywhere
