Didn't find a registered implementation for 'ip-matcher' with type URL: 'xds.type.matcher.v3.IPMatcher'

I tried to use an IPMatche cutomMatch within the RBAC filter for the IP allow/deny list, but got the following warning:

Didn't find a registered implementation for 'ip-matcher' with type URL: 'xds.type.matcher.v3.IPMatcher'

Do I need to turn on some options to enable the 'xds.type.matcher.v3.IPMatcher' ?

Thanks.

I figured out: IPMatcher can only be used within a matcherTree. Is there any way I can match an IP range within a matcherList?

[ravenblackx]

Maybe extensions.matching.input_matchers.ip.v3.Ip would be usable here?

@aguinet ? (Also question about whether we should be consolidating IPMatchers into a common proto.)

[aguinet]

I've just seen this now. I see this ticket has been closed: what's the conclusion?

[ravenblackx]

I guess the closing was because extensions.matching.input_matchers.ip.v3.Ip solved for the original problem.

My bonus question about whether xds IPMatcher and envoy matchers.ip.v3.Ip should be consolidated remains open but isn't bothering anyone right now.

@ravenblackx reopened this one to track it.
