R1
---------------
interface FastEthernet0/0
  ip address 65.166.193.4 255.255.255.0 secondary
  ip address 65.169.9.129 255.255.255.128
  duplex auto
  speed auto
  standby 1 ip 65.166.193.1
  standby 1 priority 105
  standby 1 preempt
  standby 1 track Serial0/0

R2
----------------
interface FastEthernet0/0
  description To LAN
  ip address 65.166.193.5 255.255.255.0
  no ip redirects
  duplex auto
  speed auto
  standby 1 ip 65.166.193.1
  standby 1 priority 100
  standby 1 preempt

Ok, Host 65.169.9.130 wishes to send traffic to 204.127.128.1.
65.169.9.130 has 65.169.9.129 as its gateway.

R1 has a iBGP session to R2 and sees this:

B 204.127.128.0/17 [200/0] via 65.166.193.5, 03:12:02

Host 65.169.9.130 CANNOT reach its desired destination 204.127.128.1.

Hosts on 65.166.193.0/24 can get out to 204.127.128.1 just fine
using .1, .4, or .5 as gateways.

The problem is related to outgoing packets. Assume incoming is fine
(route 65.169.9.128/25 is being announced fine).

Anyone got the answer?
