Hello!
If you specify a parameter 'metric' in file /etc/config/network for my
WiFi-client interface, then the extension of the lease IPaddress
disappears default route.
How it looks:
#route
Destination Gateway Genmask Flags Metric Ref Use
Iface
default 192.168.41.1 0.0.0.0 UG 10 0 0
wlan0-1
192.168.40.0 * 255.255.255.0 U 0 0 0
br-lan
192.168.41.0 * 255.255.255.0 U 10 0 0
wlan0-1
192.168.42.0 * 255.255.255.0 U 0 0 0
wlan0

/lib/netifd/dhcp.script script function is invoked proto_add_ipv4_route ()
from a script /lib/netifd/netifd-proto.sh:
proto_add_ipv4_route() {
local target="$1"
local mask="$2"
local gw="$3"
append PROTO_ROUTE "$target/$mask/$gw//"
}
If I change the string 'append PROTO_ROUTE "$target/$mask/$gw//"' on line
'append PROTO_ROUTE "$target/$mask/$gw/10/"' , the route will be added.
There is a 10 - metric value from the file /etc/config/network for this
interface.
But for IPv6 metric value is taken into account:
"proto_add_ipv6_route() {
local target="$1"
local mask="$2"
local gw="$3"
local metric="$4"
local valid="$5"
local source="$6"
append PROTO_ROUTE6 "$target/$mask/$gw/$metric/$valid/$source"
}"
