IPv6 subnets on exitnodes had no working local-routing path. Add a v6 address on the xvrf veth pair and install IPv6 routes via that next-hop.
Signed-off-by: Hannes Laimer <[email protected]> --- v3: - use fe80::1 and fd80::2 as suggested by @Stefan v2: - change `address6` to `address`, ifreload2 does not pick up address6. Probably had the address still attached from manualy testing so I didn't notice when I tested this for v1 src/PVE/Network/SDN/Controllers/EvpnPlugin.pm | 7 ++++++- src/PVE/Network/SDN/Zones/EvpnPlugin.pm | 2 ++ 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/src/PVE/Network/SDN/Controllers/EvpnPlugin.pm b/src/PVE/Network/SDN/Controllers/EvpnPlugin.pm index e53000a..cc21712 100644 --- a/src/PVE/Network/SDN/Controllers/EvpnPlugin.pm +++ b/src/PVE/Network/SDN/Controllers/EvpnPlugin.pm @@ -462,7 +462,12 @@ sub generate_vnet_frr_config { foreach my $subnetid (sort keys %{$subnets}) { my $subnet = $subnets->{$subnetid}; my $cidr = $subnet->{cidr}; - push @controller_config, "ip route $cidr 10.255.255.2 xvrf_$zoneid"; + my ($ip) = split(/\//, $cidr, 2); + if (Net::IP::ip_is_ipv6($ip)) { + push @controller_config, "ipv6 route $cidr fe80::2 xvrf_$zoneid"; + } else { + push @controller_config, "ip route $cidr 10.255.255.2 xvrf_$zoneid"; + } } push(@{ $config->{frr_ip_protocol} }, @controller_config); } diff --git a/src/PVE/Network/SDN/Zones/EvpnPlugin.pm b/src/PVE/Network/SDN/Zones/EvpnPlugin.pm index 6d89499..8e7ddfd 100644 --- a/src/PVE/Network/SDN/Zones/EvpnPlugin.pm +++ b/src/PVE/Network/SDN/Zones/EvpnPlugin.pm @@ -327,6 +327,7 @@ sub generate_sdn_config { @iface_config = (); push @iface_config, "link-type veth"; push @iface_config, "address 10.255.255.1/30"; + push @iface_config, "address fe80::1/126" if $ipv6; push @iface_config, "veth-peer-name $iface_xvrfp"; push @iface_config, "mtu " .
