Enabling or disabling router-advertisement (RA) messages enables you to control the routing configuration for selecting the correct network interface to communicate with its neighbors.

What is Radvd used for?

The Router Advertisement Daemon (radvd) is an open-source software product that implements link-local advertisements of IPv6 router addresses and IPv6 routing prefixes using the Neighbor Discovery Protocol (NDP) as specified in RFC 2461.

What is Radvd in Linux?

radvd is the router advertisement daemon for IPv6. It listens to router solicitations and sends router advertisements as described in “Neighbor Discovery for IP Version 6 (IPv6)” (RFC 4861). With these advertisements hosts can automatically configure their addresses and some other parameters.

How do you run a Radvd?

To configure the radvd daemon:

  1. Install the radvd daemon: ~]# sudo yum install radvd.
  2. Set up the /etc/radvd.conf file.
  3. Enable the radvd daemon: ~]# sudo systemctl enable radvd.service.
  4. Start the radvd daemon immediately: ~]# sudo systemctl start radvd.service.

How do you configure RA?

Configuring RA

  1. Connect interfaces and configure physical parameters for the interfaces to ensure that the physical status of the interfaces is Up.
  2. Configure link layer protocol parameters for the interfaces to ensure that the link layer protocol status of the interfaces is Up.
  3. Configure IPv6 addresses for interfaces.

What is RA server?

A registration authority (RA) is an authority in a network that verifies user requests for a digital certificate and tells the certificate authority (CA) to issue it.

What is RA Guard?

The IPv6 RA Guard feature provides support for allowing the network administrator to block or reject unwanted or rogue router advertisement (RA) guard messages that arrive at the network device platform.

How do I enable RA?

What information is contained in the RA messages?

RA messages contain the link-local address and the layer-2 (MAC) address of the first-hop router. Servers can listen to these and use this information to auto-configure their default gateway.

What is RA registered?

What is IPv6 enabled mean?

IPv6 stands for the Internet Protocol, version 6. It is a protocol that’s intended to replace the current version, IPv4. One of the main benefits of IPv6 versus IPv4 is that it provides a pool of nearly unlimited IP addresses. Other improvements include more efficient routing and stateless address auto-configuration.
