- IPv6 Router Solicitation. I'm currently using Wireshark on a link between 2 routers in GNS3. One has an IPV6 statically configured address and is sending regular RA messages on the link. The other router has an interface configured with SLAAC, meaning it is waiting for a RA from the other router to auto-configure its IPv6 interface.
- Router Discovery. Whereas IPv4 hosts must rely on manual configuration or DHCP to provide the address of a default gateway, IPv6 hosts can automatically locate default routers on the link. This is accomplished through the use of two ICMPv6 messages: Router Solicitation (type 133) and Router Advertisement (type 134).
The Destination Address (Layer 2 or Layer 3) A router is a piece of hardware or a software which transfers a data packet over network to other machine.In static routing we define the paths in the.

That is the IPv6 unspecified address, and you use it when you do not know an address or have an address. The IPv6 unspecified address (::/128) is explained in RFC 4291, IP Version 6 Addressing Architecture, Section 2.5.2. The Unspecified Address:
2.5.2. The Unspecified Address
The address 0:0:0:0:0:0:0:0 is called the unspecified address. It must never be assigned to any node. It indicates the absence of an address. One example of its use is in the Source Address field of any IPv6 packets sent by an initializing host before it has learned its own address.
The unspecified address must not be used as the destination address of IPv6 packets or in IPv6 Routing headers. An IPv6 packet with a source address of unspecified must never be forwarded by an IPv6 router.
Ron Maupin♦Ron Maupinthere are at least two uses of the 'unspecified address' that I am aware of.
Firstly before assigning it's first (link local) ipv6 address a node is expected to perform duplicate address detection. To do that it must send a neighbour solicitation packet but it doesn't have any address yet.
Secondly the address is used as a wildcard in the 'sockets' API for an application to tell the OS that it wants to listen on all addresses.
