[j-nsp] PPPoE

[Ben Dale]

Hi Dermot,

I can't say I've ever tried using a sub-interface for PPPoE before,  
but here's a config snippet for creating the ppp interface and binding  
it to the logical interface you've already created:

interfaces {
	pp0 {
	    unit 0 {
	        ppp-options {
	            chap {
	                default-chap-secret "$9$te9Jp0IXxd24ZxN4ZDHTQ"; ##  
SECRET-DATA
	                local-name "user at domain.com.au";
	                passive;
	            }
	        }
	        pppoe-options {
	            underlying-interface fe-0/0/0.128;
	            client;
	        }
    	    	no-keepalives;	
	        family inet {
	            mtu 1452;
	            negotiate-address;
	        }
	    }
	}
}

You can't specify an ethernet interface as a next hop, but you can  
specify the pp0.0 interface.

Cheers,

Ben

Hi,



Either I fail at searching the docs or the docs fail at providing the
info but I'm having a bit of trouble getting a working PPPoE
configuration on a J4300.



Firstly, is it possible to use a logical interface (e.g., fe-0/0/0.128)
as a PPPoE interface? The router lets me set the encapsulation on the
interface to ppp-over-ethernet but I can't take it for granted that that
means I have a working config.



Also, how do I indicate to the router what packets should bring up the
PPP session? There doesn't seem to be a way in JunOS (8.1, admittedly)
to specify that the next-hop for a given subnet is an interface.



Any ideas?



Thanks,



Dermot
