IPv4 and IPv6 Dual Stack issue with routes in /etc/network/interfaces
Hi there,
Im configuring dual-stack on a Debian machine and as soon as I uncomment "post-up and "pre-down" lines in the configuration file I get the following error: RTNETLINK answers: File exists Failed to bring up eth1. This is how my configuration file looks, as soon as I comment out the "post-up" and "pre-down" lines then my eth1 gets the IPv6 address. If I comment out the inet6 interface then my configure works perfectly adding the routes to the appropriate network. auto eth1 iface eth1 inet static address 172.12.0.1 netmask 255.255.255.0 post-up ip route add 172.16.0.0/24 via 172.12.0.50 pre-down ip route add 172.16.0.0/24 via 172.12.0.50 iface eth1 inet6 static address 2001:23::207:129 netmask 112 Please advise as I need these routes to be added on startup. Thanks Darkmode |
Needed to add pre-up modprobe ipv6 into my /etc/network/interfaces file, I assume this is because I am currently using an old disto.
