[j-nsp] uRPF config

[Sonny Franslay]

Hi everybody,

What are the difference in the following configs:

1. [edit routing-options forwarding-table]
	unicast-reverse-path feasible-paths;
   and
   [edit interfaces fe-0/0/0]
     unit 0 {
	family inet {
	    rpf-check;
        }
      }

2. [edit routing-options forwarding-table]
	unicast-reverse-path active-paths;
    and
   [edit interfaces fe-0/0/0]
     unit 0 {
	family inet {
	    rpf-check;
         }
      }

3. [edit routing-options forwarding-table]
	unicast-reverse-path feasible-paths;
   and
   [edit interfaces fe-0/0/0]
     unit 0 {
	family inet {
	    rpf-check; {
        	mode loose;
    	    }
         }
      }

4. [edit routing-options forwarding-table]
	unicast-reverse-path active-paths;
    and
   [edit interfaces fe-0/0/0]
     unit 0 {
	family inet {
	    rpf-check; {
        	mode loose;
      	    }
         }
      }

Which of these is for a loose-mode rpf in a border router deployment?

I've searched through the archive but cannot find the info.

thanks in advance,

best regards,
