1. Displaying existing IPv6 routes. First you should check, whether and which IPv6 addresses are already configured (perhaps auto-magically during auto-configuration). 1.1. Using "ip". Usage: # /sbin/ip -6 route show [dev <device>] Example: # /sbin/ip -6 route show dev eth0 2001:0db8:0:f101::/64 proto kernel metric 256 mtu 1500 advmss 1440 fe80 ...

20.08.2017 · With its implementation of IPv6 routing tables using radix trees, Linux offers subpar performance (450 ns for a full view — 40,000 routes) compared to IPv4 (50 ns for a full view — 500,000 routes) but fair memory usage (20 MiB for a full view). In a previous article, we had a look at IPv4 route lookup on Linux. Let’s see how different IPv6 is.

Extract the tunneling overhead from the MTU: root # ip link set he6 mtu 1280. Bring the tunnel up: root # ip link set he6 up. Assign the IPv6 address to it: root # ip addr add 2001:470:1F00:FFFF::2 dev he6. Route all global unicast IPv6 addresses through our 'he6' tunnel device: root # ip route add 2000::/3 dev he6.

12.05.2020 · route command in Linux is used when you want to work with the IP/kernel routing table. It is mainly used to set up static routes to specific hosts or networks via an interface. It is used for showing or update the IP/kernel routing table.

A device can be needed, too, if the IPv6 address of the gateway is a link local one. Following shown example adds a route for all currently global addresses (2000::/3) through gateway 2001:0db8:0:f101::1
