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

Subject: redistribute question
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)?
