Problems setting up on a Cisco 1603 with dynamic IP-address
![[de]](/s/countries/de.gif) Shadow Hawkins on Sunday, 01 May 2005 12:21:19
Hi,
I've got some trouble setting up my heartbeat tunnel on a Cisco 1603. The problem is that I've just got dynamic IP-adresses which change every 24 hours.
My question is: What do I have to enter for the tunnel destination value?
I mean .. Since my IP-address changes every 24 hours I actually had to change the IP-address over there on the Cisco also every 24 hours.
Are there any solutions for still using Sixxs on the Cisco with a dynamic IP-address?
regards,
phil

I think you're talking about setting the tunnel source value on the Cisco. You probably have a Dialer interface with your ISP-Connection, you can use this interface in your tunnel configuration
interface Dialer1
! your ISP connection
interface Tunnel1
description SixXS
tunnel source Dialer1
tunnel destination 1.2.3.4
this only updates your cisco automatically, you will still need to run the heartbeat daemon/AICCU on a host behind this Cisco to send the heartbeat packets.

Hi Bernhard,
first of all, thanks for your help. It helped me quite a lot to move forward in my IPv6 stuff. :)
Anyhow, there still seem to be some problems:
--snip--
router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#int tunnel0
router(config-if)#description IPv6 uplink to SixXS
router(config-if)#no ip address
router(config-if)#ipv6 enable
router(config-if)#ipv6 address 2001:6f8:900:4fd::1/64
router(config-if)#tunnel source Dialer1
router(config-if)#tunnel destination 212.224.0.188
router(config-if)#tunnel mode ipv6ip

router(config)#^Z
router#write mem
Building configuration...
[OK]
router#ping ipv6 2001:608:6::5
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:608:6::5, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

I know, I can't point static routes through myself .. But what I entered is actually that, what the howto describes.
Hmm. Any ideas? :{

The Cisco already told you the problem :-)
router(config-if)#ipv6 address 2001:6f8:900:4fd::1/64
router(config-if)#ipv6 route 2000::/3 2001:6f8:900:4fd::1
% Not allowed to point static routes through yourself
router(config)#ipv6 route 2000::/3 2001:6f8:900:4fd::1
% Not allowed to point static routes through yourself
2001:6f8:900:4fd::1/64 is the POP's address, use ::2/64 on your side.

Ahh, okay. :)
This worked. Now I can successfully ping the host from the router.

I've just got some other questions .. *g*
Assuming that I've got a /48 subnet now, and I want to connect other hosts in my LAN via IPv6 .. (I don't actually /have/ the subnet, it's not accepted yet. I hope it'll be accepted within the next days or hours).
I guess, I have to install radvd? (Warning: radvd will run on another host, then. *Not* on the router itself).
Is following Configuration correct?
--snip--
interface br0
{
AdvSendAdvert on;
#
# These settings cause advertisements to be sent every 3-10 seconds. This
# range is good for 6to4 with a dynamic IPv4 address, but can be greatly
# increased when not using 6to4 prefixes.
#
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
prefix 2001:6f8:900:4fd::2/64
{
#AdvOnLink on;
#AdvAutonomous on;
#AdvRouterAddr off;
};
};
--snap--
The problem is just, that radvd isn't running on the Cisco. How do I tell the hosts who get a address via radvd that the they have to use the Cisco for all internet traffic?

Why don't you want the router advertisements be originated by the cisco? It is the easiest thing in the world, in fact it is automatically enabled when you put an IPv6 address onto an ethernet interface.
You can tune the parameters with "ipv6 nd { ra-interval | ra-lifetime | prefix }".
