As stated before, you can't have an aggregate interface going to two individual switches.

If so, yes you can do that. If not, you won't be able to. -----Original Message----- From: medrees [mailto:medr...@isu.net.sa] Sent: Tuesday, March 15, 2011 11:31 PM To: Doug Hanks; juniper-nsp@puck.nether.net Subject: RE: [j-nsp] Load balancing using Ethernet Aggregate interface ae0 Hi Doug Thanks for your reply, my question is that "is it possible to make aggregation in two links from juniper side and the other side is connected to two different Layer-2 Cisco switches for load balance?" currently I'm connected this setup but one physical interface as primary and the other as backup inside the ae0. -----Original Message----- From: Doug Hanks [mailto:dha...@juniper.net] Sent: Wednesday, March 16, 2011 9:17 AM To: medrees; juniper-nsp@puck.nether.net Subject: RE: [j-nsp] Load balancing using Ethernet Aggregate interface ae0 If I understand your question correctly ... LACP requires a single signaling plane, so the remote devices need to be a virtual-chassis, mc-lag, VSS or some other virtualization technology. If you use a static LAG, there's no signaling at all, and the above still applies, as the packets have to be reassembled on the remote device. If the remote devices truly are separate, you will just end up black holing the traffic. In this case just using a routing protocol.

So if anyone can help me with documentation or his experience for this task send to me.
