CE 1 and CE 3 belong to VPN 1, while CE 2 and CE 4 belong to VPN 2.
■
VPN 1 uses VPN target attributes 111:1, while VPN 2 uses VPN target attributes
■
222:2. Users of different VPNs cannot access each other.
EBGP is used to exchange VPN routing information between CE and PE.
■
PEs use OSPF to communicate with each other and use MP-IBGP to exchange
■
VPN routing information.
