Hi,
I'm running eigrp between R4 & R3, ebgp between R3 & R2 and ibgp with no
sync for R3 & R1.
There are dual path from R4 to R3.
Two bgp routes from R2, one from R1 are redistributed into R4 by R3.
150.10.1.0/24 140.10.50.0/24
R4------------R3--FR-----------R2 (131.10.0.0/24) (210.10.1.0/24)
\----------/ | EBGP
igrp |
------------R1 (141.10.0.0/24)
IBGP
However, in the routing table of R4, Only the bgp routes from R2 are
redistributed into
R4 ,but the Ibgp route from R1 can not. Of course both routes are appear
in R3.
Does the route from IBGP will not be redistributed ??
Any comment are appreciated.
