Not Expanding Range from IRR

[mhlambert]

We have a route-set defined in IRR with relevant lines

route-set:  AS5050:RS-BVIU
members:    206.127.136.0/21^21-26, 209.114.140.0/23^23-24

If I run this through bgpq3, I get what I would expect:

% bgpq3 -4 -A -l foo as5050:rs-bviu
no ip prefix-list foo
ip prefix-list foo permit 206.127.136.0/21 le 26
ip prefix-list foo permit 209.114.140.0/23 le 24

(peval from irrtoolset will also expand the more-specific prefixes.)

But if I use bgpq4, it apparently doesn't even recognize the prefixes:

% bgpq4 -4 -A -l foo as5050:rs-bviu
no ip prefix-list foo
! generated prefix-list foo is empty
ip prefix-list foo deny 0.0.0.0/0

This is version 1.4 from Homebrew on macOS:

% bgpq4 -v

Hi! Thanks for the report.

I think the issue is with the rr.ntt.net server (which is the default of bgpq4, in contrast to bgpq3 which defaults to whois.radb.net).

It was recently discovered there is an issue with route-set expansion in IRRd v4: irrdnet/irrd#543
