My routing is working pretty well except that I'm having trouble with the
servers sending out ARP replies and bouncing the connections between routed
and direct.
I know the patches are supposed to squelch ARP replies from the servers for
loopback addresses (yes, they are all patched). Any ideas how to stop it?
Config:
DR with LocalNode on the first server. Second server has IP address of
222.133.104.139 (all IP addresses are random here).
VIP's of 222.133.104.{223-226} routed to both systems...
Works great, but the VIP's get arped between the two machines... Also, when I
was trying to use the second ethernet interface on the director/server to get
to the other server, all three interfaces would send out ARP's
(director/server: eth0, eth1, server2: eth0)....
How do you prevent ARP's??? Ideally you would be able to specify it with
ifconfig and I thought that the loopback wasn't supposed to cause an ARP reply
after the patches...
Kernel 2.2.13pre6 from Alan's directory on ftp.funet.fi with the
ipvs-0.8.3-2.2.12 patch applied... (2.2.12 crashed every 5 min for some
reason...)
To test I can put a permanent entry ARP entry in the test system but I Really
can't do that with the router, especially since I will want to failover.
Thanks!
