UPE3
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.
mVRRP over mVPLS
mVRRP over mVPLS indicates that mVRRP packets are transmitted by the mVSI through the
mPW.
As shown in
on the UPE and the NPEs; mVRRP runs between NPEs. mVRRP packets are transmitted through
