#8 Re: Using multiple network cards in XEN 3.0 Posted by linlan (64.140.xx.xx) on Fri 5 Jan 2007 at 20:36 I've set up a similar config with xenbr0 (eth0 - public class C) and xenbr1 (eth1 - private class C). I've created a bunch of DomNs that use both interfaces. What I find though is I can't ping any of the other Class C addresses on the xenbr1. It's like the packets aren't sent out eth1. [root@dwarf ~]# brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.feffffffffff no vif31.0 vif30.0 vif29.0 vif28.0 vif1.0 peth0 vif0.0 xenbr1 8000.feffffffffff no vif31.1 vif30.1 vif29.1 peth1 vif0.1 Everything looks okay although I'm surprised both bridges have the same bridge ID. The routes are right but when I try to ping another address it tells me the destination host is unreachable. Any suggestions on what I might do to fix or troubleshoot this would be greatly appreciated. There's no problem reaching anything on eth0.
