[j-nsp] Multiple LAG Groups / Common Layer3 Routing

[Paul Stewart]

Thanks to everyone for their replies. we are going to put the LAG portion on
standby for now due to time constraints with the project.

 

Just to reply here though, we cannot have an VLAN tagging - the 8 ports are
all connected to servers that cannot deal with VLAN tags.maybe I'm
misunderstanding the response though ;)

Something like this allows both l2 and l3 transit on the interface. 

ae0 {
    description " Connection to Blah ae0";
    flexible-vlan-tagging;
    native-vlan-id 1;
    mtu 9192;
    gratuitous-arp-reply;
    unit 0 {
        vlan-id 900;
        family inet {
            address 10.1.32.1/30;
        }
        family iso;
        family mpls {
            filter {
                input mpls-sample-in;
                output mpls-sample-out;
            }
        }
    }
    unit 999 {
        family bridge {
            interface-mode trunk;
            vlan-id-list [ 1-899 1000-4094 905 920-921 995 ];
        }
    }
}
xe-0/2/0 {
    description "Connection to blah";
    gigether-options {
        802.3ad ae0;
    }
}

xe-1/2/0 {
    description "Connection to blah2";
    gigether-options {
        802.3ad ae0;
    }
}

Hi folks..



Not sure if my subject line reads correctly or not.  MX platform running
10.0R3.10



I have eight physical interfaces and want 4 LAG groups (2 interfaces X 4 LAG
groups) - LACP Passive mode.



All 4 LAG groups must belong to the same layer3 network.



I have tried to create AE interfaces with "family bridge" however it rejects
this but I know this should be something with bridge domains?



Thanks,



Paul
