I don't have a C6 ipv6 machine but I do have a F17 which might not be too far off in behaviour... The general recommendation though is that next hop should always be via the local link FE80:: addresses (I notice your public address for gateway there)... Don't worry about the error -101 - the actual error is the unreachable bit and just says that those networks can't be reached over the lo device - which is understandable... Here's a look at my F17 server for comparison: ip -6 r s 2001:0:4137:9e76:24f8:3b1a:2598:7928 via fe80::e291:f5ff:fecc:7919 dev em1 metric 0 cache 2001:0:9d38:953c:2805:3e4f:484e:6234 via fe80::e291:f5ff:fecc:7919 dev em1 metric 0 cache 2001:0:9d38:953c:344a:332e:37f7:24f7 via fe80::e291:f5ff:fecc:7919 dev em1 metric 0 cache 2001:470:97df:1::/64 dev em1 proto kernel metric 256 expires 85879sec unreachable fe80::/64 dev lo proto kernel metric 256 error -101 fe80::/64 dev em1 proto kernel metric 256 default via fe80::e291:f5ff:fecc:7919 dev em1 proto kernel metric 1024 expires 1305sec I'm using radvd on my network ... but things shouldn't be too far off for static settings... Is the other C6 system that *is* working on the same vmware server, bare metal or on another virtualization server?
