dear all:
i have a x86 PC and i use it as a router
the kernel is 2.6.38
there are two NICs: eth0 and eth1
i configed eth0 as 10.1.0.1
and eth1 as 11.1.0.1
Linux will route between these two cards
and it worked ok in the old days
but recently, i had added a new NIC as eth2 for LAN
so i add a bridge br0 and config it as 10.1.0.1
then i configed eth0 and eth2 under br0
no ip on eth0 now
like
br0(10.1.0.1)
eth1(11.1.0.1)
/ \
eth0
eth2

LAN
LAN
i expected that the performance will be better
but unfortunately things become worse
the PC lost packets now
at first, i think maybe there is a loop Under br0, so i disconnected the
wire on eth2 or eth0
nothing changed, packets still lost
then i remove br0
config is as before
its'
eth0(10.1.0.1)
eth1(11.1.0.1)
|
LAN
then everthing becomes fine, no packet lost
i can't explain why,
any idea?
thanks
