backup agreement function collection or distribution and data synchronization

GR: Graceful restart. In order to transmitting uninterruptedly, require the router confer

to extend to support the GR ability.

MAD: Multi-Active Detection

10.1.1.4 VSF Typical Application

Figure 10-6 application of VSF in the campus data center

Fig 1-6 is the application of VSF in the campus internet. After using the VSF, it groups

several facilities together to become the single logic facility and connect to the virtual

facility. After the predigestion, the network do not need to use MSTP, VRRP protocol, it

simplifies the network configuration. At the same time, it relies on the cross facilities to

aggregate the link (The active mode must be used for port group). When some of the

members are out of order, it will not rely on MSTP, VRRP protocol etc constringency, thus

in increase the reliability.

10.1.1.5 LACP MAD

lacp mad is the dynamic aggregation method based on lacp. Each member device of

vsf has one port connecting to the middle device at least.

Notice: The middle device must be the device which supports the extended function

of lacp.
