[j-nsp] Logical routers

[Harry Reynolds]

Not sure that is true. Below is an example of two LRs sharing an ifd
that lives in each LR only in vlan-tagged ifl form:

regress at wiggum# show interfaces fe-0/3/0 
vlan-tagging;
fastether-options {
    loopback;
}
unit 1 {
    vlan-id 1;
    family inet {
        address 1.1.1.1/30;
    }
}
unit 2 {
    vlan-id 2;
    family inet {
        address 2.2.2.1/30;
    }
}

[edit]
regress at wiggum# run show interfaces terse fe-0/3/0  
Interface               Admin Link Proto    Local                 Remote
fe-0/3/0                up    up  
fe-0/3/0.1              up    up   inet     1.1.1.1/30      
fe-0/3/0.2              up    up   inet     2.2.2.1/30      



[edit]
regress at wiggum# show logical-routers 
1 {
    interfaces {
        fe-0/3/0 {
            unit 1;
        }
    }
}
2 {
    interfaces {
        fe-0/3/0 {
            unit 2;
        }
    }
}
