VRRP + OSPF (Active/Standby Backup)

VRRP + OSPF (Active/Standby Backup)

Networking Diagram

As shown in Figure 7-5, the service interfaces of both firewalls work at Layer 3, connecting to the backbone through routers and to the GGSN/P-GW through Layer-2 switches. OSPF runs between the firewall and router, and VRRP is enabled on the interface connecting the firewall to the switch.

The two firewalls work in active/standby mode. Normally, traffic is forwarded by FW_A. When FW_A fails, traffic is forwarded by FW_B. This ensures that the services are not interrupted.

Failover

  • When the link to the backbone fails, the priority of FW_A is lowered through the HRP track function configured on the interface to trigger an active/standby switchover. The active route is switched to FW_B that becomes the active device in the VRRP group, and thereby the traffic is switched over.

  • The upstream and downstream interfaces of the FW are bound to the same link group, and the HRP track function is configured to monitor these interfaces. The switchover mode in case of a fault in the link to the GGSN/P-GW is the same as that in case of a fault in the link to the backbone network.
