The output shows that Router C has one route to reach network 1.1.1.0/24, that is, Router
C<—>Router D<—>Router A.
BGP dynamic peer configuration
Network diagram
All routers run BGP. Router A needs to establish an IBGP connection with Router B, Router C, and Router
D, respectively.
Configure the BGP dynamic peer feature to simply the IBGP peer configuration. Configure Router A as
the route reflector to reflect routes among Router B, Router C, and Router D.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure IBGP connections:
# Configure BGP dynamic peers on Router A.
<RouterA> system-view
[RouterA] bgp 200
[RouterA-bgp] router-id 1.1.1.1
[RouterA-bgp] group in internal
[RouterA-bgp] listen-range 10.1.0.0 16 group in
# On Router B, configure Router A as an IBGP peer.
<RouterB> system-view
[RouterB] bgp 200
[RouterB-bgp] router-id 2.2.2.2
[RouterB-bgp] peer 10.1.1.1 as-number 200
# On Router C, configure Router A as an IBGP peer.
<RouterC> system-view
[RouterC] bgp 200
[RouterC-bgp] router-id 3.3.3.3
[RouterC-bgp] peer 10.1.2.1 as-number 200
# On Router D, configure Router A as an IBGP peer.
