
Instead of configuring each individual IBGP peer with the same settings, create a BGP Peer
Group with all the relevant settings and then assign all the IBGP peerings to that Peer Group.
This simplifies the configuration.

Set the update-source to match the local CLIP#1 address so that all BGP packets sent to the
peer will use CLIP#1 as source IP address.

Always enable BGP route-refresh capability when using BGP to advertise VPNv4 routes. A
BGP speaker only needs to keep VPNv4 routes, it received from a route-refresh capable peer,
for which it has matching import RTs on local VRFs while those that do not have a matching
import RT can be discarded without wasting resources. If a new VPN is created (hence a new
import RT) the BGP speaker is then able to request to his route-refresh capable peers that all
routes be refreshed.
To verify operation of BGP refer to section 3.6
