if your carpdev has an IP and the IP(s) on the carp interface are in the same subnet, is it best to have the real netmask on the carpdev and all-ones netmasks on the carp interface, for the case where you're carp slave. and the rule of thumb remains, one IP per subnet per rdomain in the system with the real netmask, all others all-ones - aka /32 for the one and only real protocol. > Example: > em5 - no IP > carp5 - 10.0.0.0/30 mask on carpdev em5 right. > em4 - 9.0.0.0/32 for mgmt > carp4 - 9.0.0.0/28 acting as gateway for 9.0.0.0 net on carpdev em4 > carp4 - aliases on 9.0.0.0 with /32 masks on carpdev em4 here it is better to have the /28 on em4 and /32 on the carp ifs. -- Henning Brauer, [email protected], [email protected] BS Web Services, http://bsws.de, Full-Service ISP Secure Hosting, Mail and DNS Services.
