Multiple mVRRP groups are run between the NPEs. The services are bound to different mVRRP
groups so that they can use different master NPEs. For example, the user of UPE1 uses NPE1
as the master NPE and uses NPE2 as the backup NPE; the user of UPE2 uses NPE2 as the master
NPE and uses NPE1 as the backup NPE.
NOTE
For more information about VRRP, see VRRP and VRRP6 Configuration in the Quidway S7700 Smart
Routing Switch Configuration Guide - Reliability.
mVRRP over mVPLS
mVRRP over mVPLS indicates that mVRRP packets are transmitted by the mVSI through the
mPW.
As shown in Figure 8-2, mVPLS is run between the UPE and the NPEs; the mVSI is configured
on the UPE and the NPEs; mVRRP runs between NPEs. mVRRP packets are transmitted through
