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

[Paul Stewart]

Hey Chris... nice to hear from you! ;)

That makes complete sense now and I really appreciate the detailed
response.. we have left the LAG idea behind at this point (did everything in
a virtual-switch for now) due to time constraints but need to revisit this
in a few weeks...

Warmest regards, thanks again...

Paul

Hi Paul,

Try this:

interfaces {
    /* Repeat for all the physical ports you need to put into the respective
aeX LACP groups */
    xe-0/2/0 {
       description "Connection to blah";
       gigether-options {
           802.3ad ae0;
       }
    }
    ae0 {
        aggregated-ether-options {
            minimum-links 1;
            lacp {
                active;
            }
        encapsulation flexible-thernet-services;
        unit 0 {
            encapsulation ethernet-bridge;   /* it may just be
'encapsulation ethernet' - try both */
            }
    }
    ae1 {
        aggregated-ether-options {
            minimum-links 1;
            lacp {
                active;
            }
        encapsulation flexible-thernet-services;
        unit 0 {
            encapsulation ethernet-bridge;
            }
    }
    ae2 {
        aggregated-ether-options {
            minimum-links 1;
            lacp {
                active;
            }
        encapsulation flexible-thernet-services;
        unit 0 {
            encapsulation ethernet-bridge;
            }
    }
    ae3 {
        aggregated-ether-options {
            minimum-links 1;
            lacp {
                active;
            }
        encapsulation flexible-thernet-services;
        unit 0 {
            encapsulation ethernet-bridge;
            }
    }
}

bridge-domains {
    FLAT-LAN {
	domain-type bridge;
        interface ae0.0;    /* tie all the ae's into one giant bridge domain
/ Flat LAN */
        interface ae1.0;
        interface ae2.0;
        interface ae3.0;
	vlan-id 999;      /* this is irrelevant, as it is untagged leaving
the ports - but is required */
	routing-interface irb.999 /* L3 routed interface into the
bridge-domain */ 
    }
}

- Chris.
