I'd like to maintain the default route to Spectrum automatically, but the Linux kernel only gives me two choices: pick up Spectrum's router advertisement and put that into a default route in the 'main' table, or (if you set "accept_ra_def_rtr=0"), do nothing. dhcpcd won't tell you the IPv6 gateway address since DHCP6, unlike DHCP4, doesn't assign IPv6 gateways; that …

LINUX IPV6 STATIC ROUTES – UBUNTU/DEBIAN & FEDORA/REDHAT

This was not good enough for production. After searching for some time I finally found how to configure static routes in the right manner so they would work after both reboots and ...

IP6TABLES-1.4.7(8) - LINUX MAN PAGE
Description. Ip6tables is used to set up, maintain, and inspect the tables of IPv6 packet filter rules in the Linux kernel. Several different tables may be defined. Each table contains a number of built-in chains and may also contain user-defined chains. Each chain is a list of rules which can match a set of packets.

NETLINK SOCKETS DOES NOT ADD ROUTES TO ROUTING TABLE FOR IPV6
nl->nlmsg_pid = getpid (); /* This is your own process ID*/. you need to send it to kernel, with PID 0, so replacing it with. nl->nlmsg_pid = 0; will send it to the kernel and only then kernel can incorporate it into the routing table. Another point, for sending data/control information over netlink socket, sendmsg () is a preferred way to go.

IPV6 POLICY ROUTING LINUX GOTCHAS - MIDNIGHTFREDDIE

The default rules are as shown: /sbin/ip -6 rule show # 0: from all lookup local # 32766: from all lookup main. The "gotcha" is that I decided to flush the rules before adding my own.

LINUX IPV6 HOWTO GUIDE - FAQ FOR IPV6 ROUTES - LINUXTOPIA
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".

IPV6 ROUTE LOOKUP ON LINUX - VINCENT BERNAT
Lookup trie implementation#. Looking up a prefix in a routing table comes down to find the most specific entry matching the requested destination. A common structure for this task is the trie, a tree structure where each node has its parent as prefix.. With IPv4, Linux uses a level-compressed trie (or LPC-trie), providing good performance with low memory usage.

There is no reliable way to determine this, as your local router doesn’t have to have a global IPv6 address at all. Best practice says it should, and the vast majority of routers out there will, but technically it’s possible that your router could only have link-local addresses on both interfaces and still route global prefixes.
