I'm having a problem with this lab. on R2 my BGP table is
Network Next Hop Metric LocPrf Weight Path
*> 155.1.5.0/24 155.1.0.5 0 0 1 i
*> 155.1.37.0/24 155.1.23.3 0 100 0 (65013) i
*> 204.12.1.0 155.1.13.1 0 100 0 (65013) 3 i
my routing table on R2
B 204.12.1.0/24 [200/0] via 155.1.13.1, 00:19:31
155.1.0.0/24 is subnetted, 5 subnets
C 155.1.23.0 is directly connected, Serial2/1
D 155.1.13.0 [90/2681856] via 155.1.23.3, 00:47:15, Serial2/1
C 155.1.0.0 is directly connected, Serial2/0.1
B 155.1.5.0 [20/0] via 155.1.0.5, 00:19:11
B 155.1.37.0 [200/0] via 155.1.23.3, 00:19:31
So R2 looks like it should all routes that should be are there.
R3 has the same BGP table as R2 ie everything that shpould be there is, but
there is one route missing in the routing table
B 204.12.1.0/24 [200/0] via 155.1.13.1, 01:03:15
155.1.0.0/24 is subnetted, 3 subnets
C 155.1.23.0 is directly connected, Serial2/3
C 155.1.13.0 is directly connected, Serial2/2
C 155.1.37.0 is directly connected, FastEthernet0/0

155.1.5.0 network is no there. It's being advertised by confed BGP, because
it's in the BGP table.
Network Next Hop Metric LocPrf Weight Path
* 155.1.5.0/24 155.1.0.5 0 100 0 (65002) 1 i
*> 155.1.37.0/24 0.0.0.0 0 32768 i
*>i204.12.1.0 155.1.13.1 0 100 0 3 i
Rack1R3#sh ip route
but it gets better because when you look at R1's BGP table the 155.1.5.0
network is not there.
My config is the same as the answer key's Why does R2 have all the routes and
from R3 upstream the route seems to drop off. here is the BGP and eigrp
configs of R1-R3
R1
router eigrp 2
network 155.1.13.1 0.0.0.0
no auto-summary
!
router bgp 65013

any help is welcome I'm tired
