dhcpcd-discuss

Hi there

I'm running dhcpcd 6.11.5 on x86_64 void linux with musl.  I've 
configured it to obtain a prefix from my ISP and delegate it to two 
interfaces.  At the initial launch both interfaces get a working address 
and routes but when dhcpcd tries to renew only one of those interfaces 
keeps its address and the other one stops working.

Here's my config:

#v+
noipv6rs
noipv4ll
nodhcp
nodhcp6
controlgroup wheel
hostname
duid
persistent
option rapid_commit
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
option interface_mtu
require dhcp_server_identifier
slaac private

interface enp1s0
 dhcp
 dhcp6
 ipv6rs
 ia_pd 0 enp2s0/13 enp3s0/5

interface enp2s0
 static ip_address=192.168.13.1/24

interface enp3s0
 static ip_address=192.168.5.1/24
#v-


Here's the log output since start until the first renew:

#v-

After the last line there is no more log output until the next renew.  
At this point enp3s0 doesn't have an ipv6 address set anymore.

I have no idea whether this is a problem with my configuration, with my 
ISP or with dhcpcd.

Best regards,
