Hi there,
I'm currently playing with a "quite" simple network infrastructure :
-----------
| INTERNET|
-----------
| |
---- ----
|R1|---|R2|
---- ----
| |
----------- --------------
| SWITCH |----|servers & co|
----------- --------------
R1 & R2 are running OSPF to learn routes from upstream routers that are not
symbolized here.
in order to allow redundancy for boxes behind the switch, i'm running VRRP
(freevrrpd implementation) on both R1 & R2.
All is ok ("so why the hell is he sending mails ??") ...
Now, i need to isolate some servers into vlans. So i create vlans on the
interface managed by VRRP, i told VRRP to use various vlans instead of the
parent interface ... And ... here's the probleme ...
as you might know, VRRP modify the MAC address of the network card (or of
the real parent card in case of vlans) to avoid problems when virtual IP
switch from one box to another. When VRRP changes the MAC address of the
parent ethernet card of my vlans ... i cannot ping boxes behind anymore ...
when i kill freevrrpd (he restore the real mac address) everything comes
back to normal ...
Is it a "bug" or a "feature" (ie, are vlans & ether cards linked by the mac
address of the ether card .. or something like this ?)
If anyone got an idea ...
I will try with a FreeBSD 5.2 tomorow .. i'll keep you informed :-)
Regards,
