I just created the following configuration:
vif 10 {
address dhcp
address dhcpv6
description "WAN Interface to **** via VLAN 10"
dhcp-options {
no-default-route
}
dhcpv6-options {
pd 0 {
interface eth1 {
address 1
sla-id 0
}
length 56
}
}
}Expecting that when I commited this the current default route via my PPPoE interface wouldn't be affected.
However, my router still learnt a default route via DHCP:
tim@ferrari# run show ip route
<snip>
S>* 0.0.0.0/0 [210/0] is directly connected, pppoe0, weight 1, 00:00:36
* via X.X.192.1, eth1.10, weight 1, 00:00:36
S>* 10.0.0.0/8 [1/0] via 192.168.0.15, eth1, weight 1, 03w0d17h
B>* 10.1.1.0/24 [20/0] via 10.89.90.1, wg1, weight 1, 03w0d17hI have worked around this at the moment by doing default-route-distance 220 as well:
tim@ferrari# run show ip route <snip> S 0.0.0.0/0 [220/0] via X.X.192.1, eth1.10, weight 1, 00:05:34 S>* 0.0.0.0/0 [210/0] is directly connected, pppoe0, weight 1, 00:10:03
Possibly related to https://vyos.dev/T4482 though I note if I manually request a DHCP lease refresh, it refreshes the default as well.
