Eu quero que systemd-networkd ignore a rota / s padrão empurrada pelo DHCP em uma interface.
Minha configuração de trabalho tem 3 interfaces de rede. Eu tenho um arquivo de rede para cada interface:
eth0) internet
[Match]
Name=eth0
[Network]
DHCP=yes
DNS=127.0.0.1
eth1) rede de testes local
[Match]
Name=eth1
[Network]
Address=192.168.78.1/24
IPForward=ipv4
IPMasquerade=yes
DHCPServer=yes
[DHCPServer]
PoolOffset=10
PoolSize=100
EmitDNS=yes
DNS=192.168.78.1
eth2) Conexão do roteador VPN ao site principal.
[Match]
Name=eth2
[Network]
DHCP=ipv4
[Route]
Gateway=10.3.10.1
Destination=10.100.102.0/24
Metric=0
[Route]
Gateway=10.3.10.1
Destination=10.3.13.0/24
Metric=0
[Route]
Gateway=10.3.10.1
Destination=10.3.14.0/24
Metric=0
[DHCP]
UseDNS=false
SendHostname=true
UseRoutes=false
RouteMetric=2000
vnet0) interface de ponte sem conexão com interface real para VMs
[Match]
Name=vnet0
[Network]
Address=192.168.77.1/24
IPForward=ipv4
IPMasquerade=yes
DHCPServer=yes
[DHCPServer]
PoolOffset=10
PoolSize=100
EmitDNS=yes
DNS=192.168.77.1
Como você pode ver, UseRoutes=false está definido e ainda tenho uma rota padrão na rede eth2:
default via 192.168.178.1 dev eth0 proto dhcp src 192.168.178.52 metric 1024
default via 10.3.10.1 dev eth2 proto dhcp src 10.3.10.196 metric 2000
10.3.10.0/24 dev eth2 proto kernel scope link src 10.3.10.196
10.3.10.1 dev eth2 proto dhcp scope link src 10.3.10.196 metric 2000
192.168.77.0/24 dev vnet0 proto kernel scope link src 192.168.77.1 linkdown
192.168.78.0/24 dev eth1 proto kernel scope link src 192.168.78.1
192.168.178.0/24 dev eth0 proto kernel scope link src 192.168.178.52
192.168.178.1 dev eth0 proto dhcp scope link src 192.168.178.52 metric 1024
Eu também tentei UseRoutes=no , o que também não faz diferença.
Alguém tem alguma idéia do que estou fazendo errado?
