Help about create a lab ipv6 networking…please
I am just a newer to study Linux for IPV6,and I have referenced Ipv6+linux’s howto
and i got a similiar problem when i tried to form an experimental ipv6 web,could you help me?
And my problem is as follow:
there are two ipv6 websites isolated by one ipv4 web ,and i want to enable both ends ipb6 web can visit each other,and the whole web is simulated by five pc ,each with two network cards, the physical topological struct is formed as :
A[eth0,eth1]–B[eth0,eth1]–C[eth0,eth1]–D[eth0,eth1]–E[eth0,eth1]
A:
eth0:Not used at present
eth1:202.192.1.1 2002:cac0:0102:1::3/64
B:
eth0:202.192.1.2 2002:cac0:0102:1::2/64
eth1:202.192.2.2 —-tun6to4 2002:cac0:0102:1::1/64
C:
eth0:202.192.2.3
eth1:202.192.3.3
D:
eth0:202.192.3.4 —-tun6to4 2002:cac0:0404:1::1/64
eth1:202.192.4.4 2002:cac0:0404:1::2/64
E:
eth0:202.192.4.5 2002:cac0:0404:1::3/64
eth1:Not used at present
and i have configed the web to make all the nodes can connect with each other as ipv4 network first, then i created a tunnel between B:eth0 and D:eth1,I wanted to ues them as tunnel server,my operating system is redhat 9.0,and my operration is as following:
B:eth0
>ip tunnel add tun6to4 mode sit ttl 254 remote 202.192.4.4 local 202.192.1.2
>ip link set dev tun6to4 up
>ip addr add 2002:cac0:0102:1::1/16 dev tun6to4
>ip route add 2002::/16 dev tun6to4

D:eth1
>ip tunnel add tun6to4 mode sit ttl 254 remote 202.192.1.2 local 202.192.4.4
>ip link set dev tun6to4 up
>ip addr add 2002:cac0:0404:1::1/16 dev tun6to4
>ip route add 2002::/16 dev tun6to4

and these two ends can connect smoothly with each other with ipv6 address

then, i created bidirectional tunnels between A:eth1 and B:eth0 ,between D:eth! and E:eth0 and each created tunnel’s end can connect with the other, but i A could not visit D and E,E could not visit A and B, and i have been at a loss at this focus, please help me,Thanks!

You’ll need to create it yourself. I believe there is a manpage for that.

I installed radvd using apt-get install radvd on my debian machine but the /etc/radvd.conf is missing.
Am i supposed to create it myself or it is created automatically durign radvd package installation?
please help

How can I configure my eth0 to work with ipv6 when using dhcp?

endpoint any means it will go to any ipv4 address (think default gateway for ipv4 or routed to 0.0.0.0/0

Very cool, but I have some questions:

Why that number ‘2′ at the end of the generated IPv6? Could be another number?

Why ttl is configured to ‘64′? any especial motivation?

What means “endpoint any”?

thanks

That is the anycast IP address that results in the nearest IPv4-to-IPv6 gateway.

what is this 192.88.99.1 address?

You’re right, it should be a public IP address… I didn’t want to use a real public IP address for this example.

well.. but 10.20.30.40 is used as an external ip address in this example (although 10.*.*.* address space is reserved for internal networks). So, given all that, I am rather confused what should be entered in that “local” line?
