First off, I assume you can ping your link-local address:
ping6 -I eth1 fe80::a00:27ff:fe03:5b8aSecond, you never mentioned how eth1 was assigned its IPv6 address. Given that you've tried to embed an IPv4 address within an IPv6 address (which is normally done with a 0:0:0:0:0: prefix), I'd guess you did it manually. If so, with what tools?
Thanks for the response. I'm sorry when it was misguided answer.
The setting of the IP address reaches by manual operation.
# cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO="none" ONBOOT=yes HWADDR=08:00:27:83:74:54 IPADDR=192.168.11.8 NETMASK=255.255.255.0 IPV6INIT=yes IPV6ADDR=2000:8000:12:6:192:168:11:8/64 IPV6_DEFAULTGW=2000:7000:12:6::1
First off, I'm pretty sure you've got a typo in your gateway definition: it should be 2000:8000:12:6::1 (not :7000:).
Second, I've never tested how well the init scripts expand "::" notation in IPv6 addresses. They may work fine, or you may have to expand it yourself, e.g.,
IPV6_DEFAULTGW=2000:8000:12:6:0:0:0:1
When doing static IPv6 configuration, it's probably best to set
IPV6_AUTOCONF=no
Even if all that works, however, I'm not sure where you got the 2000:8000:12:6::/64 prefix. I think the current range of routable addresses starts at 2001:0000::1. I doubt your packets will be able to traverse the Internet with a 2000:8000:: address.
If you want to do IPv6 locally, you should be able to use the link-local address space, fe80::.
If you want a globally valid IPv6 address, your Internet provider will have to give you a route or you'll have to set yourself up with a IPv6 tunnelling service.

Missing fe80::a00:27ff:fe83:7454/64.
The link-local address should always be present, but I've never done a lot a ifdown/ifup operations to see how they can muck things up.
I'd try "service network restart" to get full interface initialization.
