mapping
Network configuration
As shown in Figure 9:
• Two VPN A branches, Site 1 and Site 2, are in VLAN 5 and VLAN 6, respectively.
• The two sites use different VPN access services from different service providers, SP 1 and SP
2.
• SP 1 assigns VLAN 100 to Site 1 and Site 2. SP 2 assigns VLAN 200 to Site 1 and Site 2.
Configure one-to-two VLAN mappings and two-to-two VLAN mappings to enable the two branches
to communicate across networks SP 1 and SP 2.
