I am having an issue with networking and believe that I understand the
issue but do not know how to fix the problem. I have two servers set
up in a carp + pfsync load balancer on 2 T2000 sparc servers.
Each server is configured identically.
First I have a physical interface em0 that is plugged into a switch
set up as a swithport that is on a vlan629
Second I have a physical interface em2 that is plugged into a switch
that is trunked to multiple different vlans including vlan629. The
em2 interface is the interface that all the vlans bind to, from there
each carp interface binds to appropriate vlan.
All of the other vlans are working as expected on the em2 interface
except for vlan629. For each vlan I have created a
/etc/hostname.vlan* and they all work. Where the problems comes in
when I try to ping one of the ip addresses that are assigned to
/etc/hostname.vlan629 on either server. I can see ICMP request come
in using tcpdump but the ICMP request is not returned. My assumption
is that the vlan629 interface does not know how to route back out
through the em2 physical interface.Also when using netstat -rn it
did not show any routes for vlan629 on em2 but did show the routes for
em0.
I did some testing by destroying the em0 interface on both servers and
rebooting each server. After rebooting the /etc/hostname.vlan629
routes showed up correctly in netstat -rn and I was able to
successfully ping each em2 vlan629 interface on both servers. I
would like to be able to keep the em0 interface because it has special
pf rules that are different than the em2 interface.
Any suggestions would be greatly helpful.
