R1 is not advertising 11.11.11.11 network in eigrp
so go to R1
router ei 200
net 11.11.11.11 0.0.0.0

Hi

As my thinking 11.11.11.11 subnet is advertise via IBGP to R2.So its leanrn router as IBGP.I dont think this route will be in R2 eigrp topology tables.Due to which R2 is not advertise this route to R3.
if u advertise 11.11.11.11 subnet via eigrp it will reflect to R3 routing table..

If someone know better answer post on comment.

Please note that 11.x.x.x network is advertised in BGP. EIGRP used between R1 & R2 is just setup in order to establish reachability to run BGP on top of it. Since the BGP peering is loopback based.

Also from the name itself - the problem created is within scope of redistribution :-)

Try again... Good Luck...

Redistribute bgp into eigrp @ R1 itself

Deepak sir is this Solution ?

I haven't seen this in real GNS. By looking the Topology, I would assume the problem is IBGP isn't being redistributed into the EIGRP 200.

because by default, the redistribution on BGP will only work for EBGP into another IGP

btw, how was your lab experience?

hello all,

redistribute internal route in BGP R2,

R2(config-router)#bgp redistribute-internal

That's cool. It's work!
