redistribution bgp>ospf

Hi

Just a quick sanity check...

I'm redistributing bgp>ospf and using network statements to control how my
ospf subnets are sent to my ebgp peer, now please correct my understanding
but the ebgp peer see's the ospf routes coming from my AS number...and when
I reset this connection I can see in debug ip bgp updates the update
message for the original ospf routes when the ebgp peers synchronize will
deny my originated prefixes coming back to due to = DENIED due to: AS-PATH
contains our own AS;

So therefore there is no risk if I redistribute bgp into ospf of double
redistribution as the ebgp boundary would deny any originally originated
prefixes in the first instance?

in summary, I am using network statements to control ospf>bgp and bgp>ospf
is using redistribute keyword with tag<as number> and I can see in ospf rib
on internal devices only the tagged prefixes which I would expect.

I have seen some examples using bgp community to tag & deny but this is
only when using mutual redistribute command under both processes.

Best Regards

Tony
