When PEs and CEs use BGP to exchange routing information, you do not need to import private network routes into BGP on PEs.

In a Hub & Spoke scenario, when the Hub-CE and Hub-PE run an IGP for communication, EBGP cannot be configured on the Spoke-PE or Spoke-CE.

In a scenario where PEs and CEs use BGP to exchange routing information, if two VPN sites have the same private AS number, the AS number replacement function can replace the AS number in a received private network route with any specified AS number to prevent routes from being discarded due to repeated AS numbers.

In a CE multi-homing scenario, the BGP AS number replacement function may cause routing loops.
BGP SoO can be used to prevent routing loops at a VPN site.
