Hi All,

I am noticing that solutions to many of the labs I am doing do not include
distribute lists
or route-maps to prevent route-feedback at mutual-redistribution points.
Doyle, in his
redistribution chapter (page 717) also does not use them but mentions on
page 769 that you should
always use them "any time a router is performing mutual-redistribution -
the mutual sharing of routes between two
or more routing protocols - route filters should be used to ensure the
routes are advertised in only one direction."

so does anyone have any comments on this? Are you all using route-maps to
control redistribution at
mutual-redistribution points - like a router redistributing between ospf
and eigrp? Any rules of thumb to go by?
Sometimes it's a real pain to get setup and can cost you alot of time -
like why the defualt route is
not getting propagated.

Thanks,

Julie Ann
