Hi Ben,

I think this will be typically seen in a scenario where the task asks
you to advertise a directly connected interface into RIP without using
network x.x.x.x command under router rip.

HTH,
Prasad.

Subject: RIP redistribution

Hi
As I understand IGP redistribution, it redistributes all the routes from
the
source IGP, as well as connected routes on which the source IGP has been
enabled. Most examples I have seen of redistribution between RIP and
other
IGPs also include "redistribute connected" into RIP, even when there is
no
route-map filtering the redistribution of the other IGP into RIP.

For example, you will typically see the following:

router ospf 1
  red rip sub
router rip
  red ospf 1 metric 1
  red conn metric 1

Why do we need to explicitly redistribute connected routes into RIP,
when
this action is already implicit in the IGP (OSPF) redistribution into
RIP?

TIA
Ben
