IPv6 in hostgroup in community edition

[wdoekes]

I understand that not everything in Fastnetmon CE is IPv6 capable. E.g.:

fastnetmon/src/actions/gobgp_action.cpp

Lines 134 to 162 in a2d2d0d

	if (fastnetmon_global_configuration.gobgp_announce_host_ipv6) {
	IPv6UnicastAnnounce unicast_ipv6_announce;
	std::vector<std::string> host_ipv6_communities;
	// This one is an old configuration option which can carry only single community
	host_ipv6_communities.push_back(fastnetmon_global_configuration.gobgp_community_host_ipv6);
	for (auto community_string : host_ipv6_communities) {
	bgp_community_attribute_element_t bgp_community_host;
	if (!read_bgp_community_from_string(community_string, bgp_community_host)) {
	logger << log4cpp::Priority::ERROR << "Could not decode BGP community for IPv6 host: " << community_string;
	// We may have multiple communities and other communities may be correct, skip only broken one
	continue;
	}
	unicast_ipv6_announce.add_community(bgp_community_host);
	}
	unicast_ipv6_announce.set_prefix(client_ipv6);
	unicast_ipv6_announce.set_next_hop(gobgp_next_hop_host_ipv6);
	gobgp_client.AnnounceUnicastPrefixLowLevelIPv6(unicast_ipv6_announce, is_withdrawal);
	}
	if (fastnetmon_global_configuration.gobgp_announce_whole_subnet_ipv6) {
	logger << log4cpp::Priority::ERROR << "Sorry but we do not support IPv6 per subnet announces";
	}

But also there is the impossibility of adding an IPv6 address to a hostgroup:

fastnetmon/src/fastnetmon.cpp

Lines 550 to 556 in a2d2d0d

	// hostgroup = new_host_group_name:11.22.33.44/32,....
	split(splitted_new_host_group, value, boost::is_any_of(":"), boost::token_compress_on);
	if (splitted_new_host_group.size() != 2) {
	logger << log4cpp::Priority::ERROR << "We can't parse new host group";
	return;
	}

Are there any plans to improve this?

Thanks!

Hello!

Thank you for your query!

Hostgroup support is very limited in Community edition, IPv6 hostgroups are not supported. If you need it then I can suggest Advanced edition which has full support of both IPv4 and IPv6 hostgroups: https://fastnetmon.com/docs-fnm-advanced/fastnetmon-advanced-per-host-hostgroups/
