(usagi-users 02336) Re: RADVD

At Naval Research Lab (NRL), we setup linux 7.3 with MIPL 0.9.5. doing exactly what you are trying to do. We successfully switched the MN from one AP to another and make the MN talked back and forward between two networks.

We did have some problem with some AP. We tried Linksys, 3com, and DLINK. Only DLINK can carried and forward IPV6 traffic. I suggest you use the MN to ethereal the AP and make sure to can see RADVD's traffic. Then you should make sure you have an IPV6 address on your MN. Then you can switch to another network where the Corresponding node is. I don't see you CN. What are you trying to do without a CN?

Good luck.

Hello,  I hope some one can direct me to solve my problem.

I am trying to test Mobile IPv6, I am using LapTops (LT)using Lucent and CISCO cards. The objective is just to show transparent mobility with IPv6. I am having problems setting up the router so that radvd can run properly.

LT1 (HA)has a wire interface (eth0) that is connected to the LAN (IPv4) with Subnet ID 1, and eth1 is wireless and it has the subnet ID of 2
LT2 (MN) has one wireless interface (eth0) and it's subnet ID is 2
LT3 (ROUTER) has two wireless interfaces, one (eth0) goes to the access point that is connected to another subnet (IPv4) and eth1 has the subnet ID of 3

I have some questions about the behavior of the radvd and some others regarding the router configuration.

I am having problems setting up the router so that radvd can run properly. As of today, I have configured the HA, /etc/network-mip6.conf looks as follows:
FUCTIANALITY=ha
TUNNEL_SITELOCAL=yes
DEBUGLEVEL=1
MIN_TUNNEL_NR=2
MAX_TUNNEL_NR=3
HOMELINK=eth1

The /etc/radvd.conf is set so that it will advertice 3ffe:302:11:2::/64

Now since the Mobile is also configure to be in the same subnet, it will listen to the radvd and it uses the prefix to set itself with and Global IP v6 address by appending the MAC address and the fffe. In addition to this address it also set another Ipv6 Global address where the prefix including the subnet is the same as the other but the Interface ID looks to be set at random. IS THIS THE CORRECT BEHAVIOR? what is the other Global address used for?

Since I was not having much luck in setting up the router, to run radvd and test the mobile going from one subnet to another, I decided to set the LP3 as a home agent but with subnet 3 and see if radvd will run, I did not have any luck I check and the kernel settings of LP1 and LP3 are the same, at least in the network configuration portion. Since I the time I was testing LP1(eth1) LP2(eth0) and LP3(eth1) had all the same ESSID, I notice that the LP3(eth1) was actually using the LP1's radvd with subnet 2 to set Two Global addresses, one use the MAC of its eth1 interface to set the Interface ID and the other Interface ID of the second Global ID was set at random I think.
Is this the correct behavior? As I mention above LP3 had a subnet of 3 and it pickup a radvd with the subnet 2 to set it's Global Ip address?

I will really appreciate any help.
In the case of the router, I did set ipforwarding in IPv6 but still did not work.


Thank you
