How to make IPv6 static routes persistent on CentOS?

Question

Static routes are forgotten once the network service is restarted. However, IPv4 static routes can be made persistent by adding them to /etc/sysconfig/static_routes. This file is read by the network service when (re)starting and the static routes are added to the routing table.

This is the relevant code from /etc/init.d/network

# Add non interface-specific static-routes.
if [ -f /etc/sysconfig/static-routes ]; then
    grep "^any" /etc/sysconfig/static-routes | while read ignore args ; do
        /sbin/route add -$args
    done
fi

However, no such file seems to exist for IPv6 static routes, which are lost upon network restart. Is editing the /etc/init.d/network script the only way? (So that it reads from a manually created file storing IPv6 routes and adds them to routing table when network (re)starts).

I don't run CentOS or Red Hat to check, but some documentation point to /etc/sysconfig/static-routes-ipv6. Complete documentation is available at http://www.deepspace6.net/projects/initscripts-ipv6.html This is the example given:

#Device   IPv6 network to route   IPv6 gateway address
eth0      fec0:0:0:2::/64         fec0:0:0:1:0:0:0:20
eth0      2000::/3                3ffe:ffff:0000:f102:0:0:0:1
