Questions tagged [radvd]

The router advertisement daemon (radvd) is run by Linux or BSD systems acting as IPv6 routers. It sends Router Advertisement messages, specified by RFC 2461, to a local Ethernet LAN periodically and when requested by a node sending a Router Solicitation message. These messages are required for IPv6 stateless autoconfiguration.

Why use DHCPv6 over Stateless Address Autoconfiguration?

IPv6 and RFC 2462 provide a means for hosts to configure their own IP addresses via stateless address autoconfiguration. To me this seems like the bee's knees, and it leaves me wondering why someone would want to go through the trouble of…

I found that there are some clients which when they are on an IPv4 network learn their current time zone through DHCP option number 101. On an IPv6-only network where an IP prefix is advertised by radvd on Ubuntu Server 14.04 these clients do not…

How to configure radvd, dhcpd6, routing and /64 subnet based on delegated prefix by DHCPv6-PD server?

My ISP has just started IPv4/IPv6 dual stack service. In order to connect IPv4/IPv6 internet, almost all users usually use a CPE leased by the ISP. But I want to use my Linux router instead of such CPE, because my router has so many roles(a lot of…

IPv6: using a link mtu greater than the mtu of the default route

When configuring an IPv6 LAN it may be desirable to use router advertisements to announce a link MTU of either the standard 1500 bytes or something larger to enable usage of jumbo frames, perhaps 9000. This will allow communication between hosts on…

I'm planning an IPv6 mesh-network with multiple gateways (routers to the internet). The connection between the gateways is not that great. The plan is that every gateway should announce two prefixes: One "global", like 2001:DB8:1::/64, and one…

I have two ISPs for my home network. They are connected to two separate routers. If I run radvd and dhcpd on both routers at the same time, I get no IPv6 connectivity. My IPv6 connectivity only works if only one of the routers is running radvd and…
