Neighbour Solicitation & Advertisement

Hi,

How to enable Neighbour Solicitation and Neighbour Advertisement messages possible between two unix hosts (AIX and FreeBSD) using link-local IPv6 address? I have already Global address for both unix systems. Ping works only on Global IPv6 address and not on link-local IPv6 address.

Please help.
 
Keep in mind that link-local addresses are non-routable. Both hosts therefor need to be in the same broadcast domain.

Hi,

Same broadcast domain needed for neighbour solicitation. Please explain me. Am now just starter of networking.
 
It means they both need to be on the same network, there cannot be a router between them.
If you need to traverse one or more routers you'll need to use the global address.

Hi,

Both my unix systems are connected via ethernet cable. Hope they are in the same domain. Please reason out why they don't respond to neighbour solicitation.
 
Do a traceroute6(8) on the global address. If there are any "hops" in between it means there are routers between the two hosts. In that case you can't use the link-local addresses.

Hi,

I did traceroute6 and got following output:
Code: 
# traceroute6 -s 2010::5ef3:fcff:feb6:59bc 2010::214:5eff:feb8:2abf 64
traceroute6 to 2010::214:5eff:feb8:2abf (2010::214:5eff:feb8:2abf) from 2010::5ef3:fcff:feb6:59bc, 64 hops max, 64 byte packets
 1  2010::214:5eff:feb8:2abf  0.190 ms  0.081 ms  0.078 ms
Can you please explain me what they mean to and how to make respond to neighbour solicitation messages?
 
Ok, this tells me there are no routers in between.

It also tells me neighbor solicitation works, if it didn't work this would fail.
