example
Network requirements
As shown in Figure 71 :
• Two VPN A branches, Site 1 and Site 2, are in VLAN 10 and VLAN 30 respectively. The two site
use different VPN access services of different service providers, SP 1 and SP 2. SP 1 assigns VLAN
100 for Site 1, and SP 2 assigns VLAN 200 for Site 2.
• Configure one-to-two and two-to-two VLAN mappings to enable the two branches to communicate
across networks SP 1 and SP 2.
