    Title: RE: redistribute question
    
   I think you are right,but I still have some confusion at
   redistribution.
   another question,if you have another interface in r2 not run ospf,but
   you use redistribute connected sub,why the connected route can't be
   redistribute to rip.
   thanks

     1) when doing redistribution, the router will only redistribute
     those 'valid routes' in its routing table. in r2's routing table,
     it only has 10.0.1.0 learned from rip, so it will only redistribut
     10.0.1.0 from rip to ospf. it does not have 10.0.1.0 learned from
     ospf (IN ITS ROUTING TABLE), so it wont do the reverse
     redistribution. (for directly connected network, the rule is
     slightly different.)
     
     2) ospf router will choose intra-area routes first, then
     inter-area. external routes are less preferred, even if they have
     higher metric.
     
     again, correct me if i am wrong

     hi all,
     have a question,thanks
     10.0.1.0/24--other router--r1------------r2-------20.0.1.0/24
                     rip rip rip and ospf
     r2 have 10.0.1.0 route form rip,it metric is 5,if do mutual
     redistribution on r2 and set the metric=1 to the route of
     10.0.1.0,why
     r2 can't advertise 10.0.1.0 to r1(I think r2 have a better metric
     than
     learned from r1,so it should advertise the route to r1)?If it's
     because
     split horizen,please explain it,thanks
     
     another question,thanks
     if a router run ospf and redistribute connected subnet,why the
     other
     ospf routers choose the internel route of interface over the
     external
     from redistributed(them all have the adm distance of 110 and the
     external route have cost 20,the internal route have cost 1100)?
