IRRDB for v6 only peers

[stefan6dev]

Hi @natesales,

we have some peers, there have only IPv6 Sessions to us. We set in template filter-irr: true, but then the config build failed:

FATA[0002] peer has a prefix filter defined but no IPv4 prefixes

Is there any workaround to deploy only v6 only Sessions with IRRDB Filter?

Thanks!

Could you post an abbreviated config that causes the error? Here's a quick example that worked for me:

asn: 65520
router-id: 192.0.2.1
cache-directory: test-cache
peers:
  Example 1:
    asn: 112
    as-set: AS112
    filter-irr: true
    neighbors:
      - 2001:db8::1

# pathvector generate --dry-run --config test-conf.yml
INFO[0000] Processing AS112 Example 1                   
INFO[0000] BIRD config validation passed 

# grep -E 'define .*_PFX.*' test-cache/AS112_EXAMPLE_1.conf -A 2
define AS112_EXAMPLE_1_PFX_v4 = [
  192.31.196.0/24,
  192.175.48.0/24
--
define AS112_EXAMPLE_1_PFX_v6 = [
  2001:4:112::/48,
  2620:4f:8000::/48

In your Case, AS112 have v4 Prefixes. My downstreams have only IPv6 and than the problem will be happend

Got it, thanks for the clarification. I've just released v5.5.0 including commit 07dce10a1be5257aa8cd2478c33bbde346e465c5 to address this use case. Could you give it a try and let me know if it's working for you?

Works for me, thanks 👍
