Hey!
I am updating the route/inetnum objects in the RIPE database and I am
wondering if I have to create more specific route objects. For example,
I have the following routes announced:
- 89.145.160.0/21
- 89.145.160.0/22 (FR7)
- 89.145.164.0/23 (DK2)
- 89.145.166.0/23 (GV2)
Each more specific route is announced in a different location. Should I
create only the top route object or should I create a route object for
each announce?
If I look at bgpq3, I see by default, it uses exact matches:
$ bgpq3 -4 -J -E AS61098 | grep 89.145
route-filter 89.145.160.0/21 exact;
route-filter 89.145.160.0/22 exact;
route-filter 89.145.164.0/23 exact;
route-filter 89.145.166.0/23 exact;
However, I use it this way:
$ bgpq3 -R 24 -4 -J -E AS61098 | grep 89.145
route-filter 89.145.160.0/21 upto /24;
But I am concerned some people may build filters using only exact
matches, so it seems safer to have route objects for more specifics.
