Sep 21,  · Hi aLL! i am trying to set an IPv6 network composed of redhats. as a test case, i gave two machines on the same link the same IPv6 address. on the second machine awaking, it sends neighbor solicitation for the address it wishes to acquire. naturally, the other machine which is already up, sends neighbor advertisement stating that the address is in use.

Neighbor discovery was the IPv6 successor for the ARP (Address Resolution Protocol) in IPv4. You can retrieve information about the current neighbors, in addition you can set and delete entries. The kernel keeps tracking of successful neighbor detection (like ARP in IPv4). Jul 13,  · How does IPv6 neighbor discovery work? Designers of IPv6 have taken slightly different way in address resolution. When you look at the ARP packet, you can see that there is protocol field, protocol size etc i.e IPv6->MAC resolution could be done via ARP but we have ICMPv6 instead of ARP in IPv6. First assign our IPv6 address on PC1 and vSRX. I'm trying to setup a Linux Router (LXC, el7.x86_64) with IPv6. The provider is Hetzner and I got 2 subnets, one /56 and a / They have setup the routing to my LL Address and my default gateway is . The Neighbor Discovery (ND) protocol is used by hosts and routers for mutual discovery on locally connected nets [RFC ]. This protocol replaces two protocols in IPv4. One of these protocols, no longer needed in IPv6, is ARP.
