Why is an extra Gateway added to Linux?

Question

linux

Colleagues, tell me, for what reasons, after systemctl restart network, extra routing entries are added to the routing table?

There are two interfaces:
DEVICE=enp2s0f0
NAME=enp2s0f0 TYPE =
Ethernet
BOOTPROTO=static
ONBOOT=yes
IPV6INIT=no
USERCTL=no
IPADDR=10.77.39.105
NETMASK=255.255.255.0
GATEWAY=10.77.39.106

DEVICE=enp2s0f2 BOOTTERnetEPETOthernetETO2 =static ONBOOT=yes IPV6INIT=no USERCTL=no IPADDR=10.205.240.220 NETMASK=255.255.255.248


after systemctl restart network, an extra route and an
extra GateWay appear, although it is not specified in network-
scripts scope link src 10.77.39.105 metric 103
10.205.240.216/29

Answer 1

try adding the line "DEFROUTE=no" on the interface where there should be no default

Answer 2

See what it says:
nmcli device show
and
nmcli con show

Answer 3

Are there configs here?
