Hi Group,
Trying to do some IBGP from Doyle II and from Hutnik's All-in-1-Lab 2nd
edition. I know I'm doing something wrong - just can't figure out the
issue. I'll use Hutnik's stuff - from lab #48 - page 533:
AS 100 | AS 200
|
RtrA-S0-------------------S0-RtrB-E0-------------E0-RtrC
S0 192.1.1.1/24 | S0 192.1.1.2/24 E0
193.1.1.2/24
L0 1.1.1.1/24 | E0 193.1.1.1/24
| L0 2.2.2.2/24
AS 100 | AS 200 AS
200
Basically, RouterA is in AS 100 connected via S0 to RouterB (AS 200) on
RouterB's S0 and using BGP. RouterB and RouterC are connected Ethernet and
using IBGP for AS 200. I'm trying to get Router C to be able to hit
RouterA's ints. I'm doing the basics of no sync on Router C and B and also
having Router B announcing itself as next-hop-self. I've also cleared ip
bgp * on router B and C. Still no-go. I can hit RtrA from RtrB S0
interface but not from RtrB's E0 interface using an extended ping. So what
is wrong with Router B? What am I missing?
Router A's config:
!
hostname RouterA
!
interface Loopback0
ip address 1.1.1.1 255.255.255.0
!
interface Serial0
ip address 192.1.1.1 255.255.255.0

Like I wrote at the top, this is just for my lab setup. Thanks in advance!!
