Re: bgp problem

Thanks guys.

I saw my mistakes .In r2( another point I have redistributed bgp into
ospf).and there ospf routes in does not effect for r5 table becuase it has
learn them from R1 e-bgp neigbhor.

But the same routes comes to r1 and the strange thing happened.R1 learned
these routes via ibgp neigbor which ad is 170.Since ospf ad is 110 in R1 I
have got rib failure.
