Hi I have a problem with RA. My BIRD config: http://wklej.org/hash/81158faf8c6/ My network config: Protocol radv dc1 on router 1 is "master", protocol radv dc2 on router 2 is "master". vlan 10 - 14 On each vlan interface, eg bond1.10, are assigned addresses (with keepalived): eg 2001:67c:2ad8::1/64 and 2001:67c:2ad8:1::1/64 Problem is on router 2 and protocol dc2. When I assign the address on vlan interface, eg 2001:67c:16f8:2::1/64 dev bond1.10 on router 2, hosts in this vlan recive addresses with this prefix. Host in vlan 10 3: eth0.10@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 inet6 2001:67c:16f8:3:c9dd:c2cb:611e:bcfd/64 scope global temporary dynamic valid_lft 86397sec preferred_lft 14397sec inet6 2001:67c:16f8:3:216:3eff:fe35:578b/64 scope global dynamic valid_lft 86397sec preferred_lft 14397sec inet6 2001:67c:16f8:2:c9dd:c2cb:611e:bcfd/64 scope global temporary dynamic valid_lft 86397sec preferred_lft 14397sec inet6 2001:67c:16f8:2:216:3eff:fe35:578b/64 scope global dynamic With protocol dc1 on router 1 is everything ok. Hosts don't recive any addresses. Why host recive address from router? -- Miłosz

Hello If i understand your problem correctly - they shouldn't get addresses because of 'autonomous off' option? You could try (on a host) to remove these addresses by hand and then run tcpdump (like 'tcpdump -vv -s 0 -n -i ethX ip6') on a host to see which packet with which content caused these addresses reappear. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

Hi. If I remember correctly tcpdump -i ethX -nvv icmp6 and 'ip6[40:1] = 134' should show the router advertisments being heard. there might be few minutes between them so you need to wait a bit. mk
