- B. When BGP is used to exchange routing information between PE and CE, if the autonomous systems where the two VPN sites are located use the same private AS number, the AS number replacement function can be used to replace the received private AS number with any specified AS number. The AS number in the network route to prevent the route from being discarded due to repeated AS numbers
- C. When BGP is used to exchange routing information between PE and CE, there is no need to import private network routes into BGP on PE.
