6to4 on a Cisco

Has somebody ever configured 6to4-tunneling on a Cisco ???

I tried, but I can't get it work. I have been using the IPv6 kit from
Microsoft for Windows2000, which perfectly connects to the microsoft
6to4-relay router, but when I try to use my own Cisco I get the following
c:\>6to4cfg -R 213.x.x.x
Probing 6to4 relay router 213.x.x.x...
Could not reach a 6to4 relay router.

This means that to problem is with the Cisco router. I got the config from
the IPv6-IOS command list:
I use the following IOS version:
IOS (tm) 3600 Software (C3620-IS-M), Experimental Version
12.1(20001029:175720) [otroan-samhain 114]

<config for Sixco>
interface Tunnel0
 description Used for 6to4 translations
 no ip address
 no ip redirects
 no ip route-cache cef
 ipv6 unnumbered Ethernet0/0
 tunnel source Ethernet0/0
 tunnel mode ipv6ip 6to4
interface Ethernet0/0
 ip address 213.x.x.x
 no ip redirects
 no ip proxy-arp
 ip route-cache flow
 ipv6 address 2002:XXX:XXX::/48 eui-64
ipv6 route 2002::/16 Tunnel0

b.t.w. Static tunnels to my linux-box work fine !
