1. I did have "update-source" command...
2. loopback interfaces are pinging on both routers...
I also wish that it is true that there is no limitation for ibgp multihop...
However, based on my following test, the only conclusion I came up with is
that either I missed something that's really obvious or Cisco does not
support ibgp multihop.
R2:
interface Loopback0
ip address 2.2.2.2 255.255.255.0
no ip directed-broadcast
router bgp 65001
no synchronization
bgp confederation identifier 100
neighbor 3.3.3.3 remote-as 65001
neighbor 3.3.3.3 update-source Loopback0
R2#ping 3.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
!!!!!
