Works for me, I use routers2 too.  My weathermap config has things like 
this for LINK DEFAULT:

 OVERLIBGRAPH /cgi-bin/routers2.cgi?rtr=routers%2F{link:this:src}.cfg&if={link:this:ip}_{link:this:int}&page=image
 TARGET /net/db/mrtg/routers/{link:this:ip}_{link:this:int}.rrd:ds0:ds1
 INFOURL  /cgi-bin/routers2.cgi?rtr=routers%2F{link:this:src}.cfg&bars=Cami&xgtype=d&page=graph&xgstyle=n&xmtype=options&if={link:this:ip}_{link:this:int}

with the links looking like this:

LINK Cur1-Cur2
        NODES curran1 curran2
        SET src curran1
        SET ip A.B.C.D
        SET int 1

and NODE DEFAULT might have:

 INFOURL /cgi-bin/routers2.cgi?rtr=routers%2F{node:this:name}.cfg&bars=Cami&xgtype=d&page=graph&xgstyle=n&xmtype=options&if=__compact

You may prefer different versions of the graphs; just find the one you 
want from routers2 and gets the URL, just as Howie mentions.
