Pivoting and routes

Adding routes

Using IP:

# /sbin/ip -6 route add <ipv6network>/<prefixlength> dev <device>

Example:

# /sbin/ip -6 route add default dev eth0 metric 1

or

# /sbin/ip -6 route add <ipv6> via 2001:0db8:0:f101::1

Metric ”1” is used here to be compatible with the metric used by route, because the default metric on using ”ip” is ”1024”.

Using "route":

Usage:

# /sbin/route -A inet6 add <ipv6network>/<prefixlength> dev <device>

Example:

# /sbin/route -A inet6 add default dev eth0

Not so often needed to use by hand, configuration scripts will use such on shutdown.
