Dukungan untuk route default IPv6
Salah satu idea dari IPv6 adalah routing hierarkis, oleh karenanya akan lebih sedikit routing entri di butuhkan di router. Ada beberapa isu di kernel linux saat ini
Client (tidak merouting paket)
Client can setup a default route like prefix “::/0”, they also learn such route on autoconfiguration e.g. using radvd on the link like following example shows:
# ip -6 route show | grep ^default default via fe80::212:34ff:fe12:3450 dev eth0 proto kernel metric 1024 expires 29sec mtu 1500 advmss 1440
7.6.1.2. Routers in case of packet forwarding
Older Linux kernel (at least <= 2.4.17) don't support default routes. You can set them up, but the route lookup fails when a packet should be forwarded (normal intention of a router). If you're still using such older kernel, “default routing” can be setup using the currently used global address prefix “2000::/3”.
Note: take care about default routing without address filtering on edge routers. Otherwise unwanted multicast or site-local traffic can leave the edge.
