I can't get IPv6 routing to configure correctly despite everything I've read saying it should
This is my network config on a fully-updated CentOS 5.8 system:
# cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=my.hostname.com
GATEWAY=aaa.bbb.ccc.ddd
IPV6_DEFAULTGW=2a02:aaaa.bbbb::1
IPV6_DEFAULTDEV=eth0
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=yes
DEVICE=eth0
BOOTPROTO=static
HWADDR=52:54:00:68:42:1E
IPADDR=000.111.222.333
NETMASK=255.255.255.128
IPV6INIT=yes
IPV6ADDR=2a02:aaaa.bbbb:178:209:50:230:0/112
Attempts to use the IPv6 address fail. For example:
# ping6 -c 2 2a00:1450:4016:800::1013
connect: Network is unreachable
However it works if I manually enter these 2 lines:
# route -A inet6 add ::/0 dev eth0
# ip -6 route add 2000::/3 via 2a02:aaaa.bbbb::1 metric 1
# ping6 -c 2 2a00:1450:4016:800::1013
PING 2a00:1450:4016:800::1013(2a00:1450:4016:800::1013) 56 data bytes
64 bytes from 2a00:1450:4016:800::1013: icmp_seq=0 ttl=57 time=91.2 ms
64 bytes from 2a00:1450:4016:800::1013: icmp_seq=1 ttl=57 time=95.3 ms
These are the routing table entries added by my hand-added configuration:
2000::/3 via 2a02:418:6a04::1 dev eth0 metric 1 expires 21333054sec mtu 1500 advmss 1440 hoplimit 4294967295
default dev eth0 metric 1 expires 21333054sec mtu 1500 advmss 1440 hoplimit 4294967295
So... given the parameters set in my config files, why are the CentOS v5.8 initscripts not configuring my IPv6 routing correctly?
One more thing. I get this output on network start up (prior to hand-configuration):
Bringing up interface eth0: WARN : [ipv6_add_route] 'No route to host' adding route '::/0' via gateway '2a02:aaaa.bbbb::1' through device 'eth0'
Thanks.
