Dear All,

Question1
My understanding regarding BGP update:
1. routes receive from IBGP peer only sent ot EBGP peer
2. routes receive from EBGP peer sent to EBGP peer and IBGP peer.
right ?

I configure 4 routers
A--------------B------------C--------------D

B & C let say in AS 1000
A in AS 2000
C in as 3000

Configuration:
All router configured with synronization on.
I set B to have neighbor <IP A> next-hop-self
I set C to have neighbor <IP B> next-hop-self
I inject loopback in D into BGP.

with this configuration, all of the router should have D loopback in their BGP
table, right? But it is not...? D loopback routes only appear in router B,C
and D only.

Question2

Anyone ever see or configure in BGP confederation but one of the router is not
joining the confederation for example 4 router in AS 1000 with BGP
confederation identification 50. All router is in full mesh configuration

I set in all 3 router

router bgp 1000
bgp confederation identifier 50

the other one router with no bgp confederation identifier 50

How this effect the bgp confederation?

Regards,
Prio
