All
I have the following scenario:
IGRP IGRP/BGP (6075) BGP (6075)
R1 ----------------- R2 --------------- R3
(.2) (.1) (.4) (.30) 200.200.200.1/24 loop 0
192.168.209.0/24 192.91.152.0/27
R3 is running BGP in AS 6075
R2 is running BGP in AS 6075 and IGRP
R2 is redistributing BGP into IGRP but it is not working. I can not get the
200.200.200.0/24 network redistributed from BGP into IGRP. This scenario
above will work if R2 and R3 are EBGP neighbors (ex R2 AS 6075 and R3 AS
100) but not when they are IBGP neighbors. What fundamental BGP or
redistribution concept am I missing? Does it have to do with the origin of
the route? All relevant portions of the configs and bgp/routing tables are
included below. I've even tried replacing IGRP w/OSPF, RIP, and EIGRP with
no luck. Please assist. Thanks,
