Hi
Im having issues setting up MC LAG on a pair of ex4600 with the recommended release code D40.
I have the following topology:
link xe-0/0/23 is used exclusively for the ICCP traffic
and ae0 is the ICL for the data plane.
from ex4600 PE1 on left side
[ multi-chassis ]
multi-chassis-protection 10.1.1.2 {
interface ae0;
}
[interfaces irb ]
arp-l2-validate;
unit 3999 {
family inet {
address 10.1.1.1/30;
}
}
[interfaces ae0]
description "EtherChannel between ex4600 ICL";
mtu 9216;
aggregated-ether-options {
link-speed 10g;
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members [ 10-16 18 20 30 40 50-51 55 60-65 70 80-83 90-91 100 111 114 117 120 123 150-151 279 350 1000 ];
}
}
}

}
}
}
I originally had the multi-chassis protection link as xe-0/0/23.
When I connect the client with both links, everything looks ok but I am getting traffic looping.
the iccp is established and the show interface mc-ae showed the ae6 up-up on both peers
and errors like:
Jan 17 00:21:19 rtaggtmp01 l2ald[1735]: L2ALD_FREE_MAC_FAILED: ERROR:FwdE:0x9bffd00 EFlag:0x1802101f RGID:0001 AEID:0006 SERVICE-ID:01 UNIT:00 PEERID:16843018MAC: 08:5b:0e:72:4d:ae moved: already in RMAC List

Reading docs last night it states that the protection link should be the ICL, Which I understand to be the ae0 interface.
thus indicated in the code above.
I shutdown the interface on second ex4600 towards the client
then enabled mc-ae on the ae6 on primary ex4600.
the first ex4600 complains that protection link is not configured.
so questions are:
1. Which link should be the multi-chassis protection link, the ICCP link xe-0/0/23 or the ICL ae0?
2. As this client is not ONLY attached to the ex4600 pair , there are other devices connected in and there is currently RSTP running correctly in the network, what if anything needs to be done? I saw some comments about having to set the bridge ID to be the same on both mc-lag boxes.
3. Is anything else wrong with the config?
thanks
