Four customer sites are connected through an EoMPLS-based VPLS over an MPLS provider.You
are migrating from OSPF to multi-level IS-IS as the routing protocol to run on the four CE
routers, and connectivity between all four sites is required. Youwant to control which CE or CEs
will be elected as the Designated Intermediate System. Which two key aspects should be taken

segment.
C.
One of the CE routers will be elected as the DIS based on interface priority then highest MAC
address.
D.
It is recommended to use point-to-point link type on the CEs.
E.

the DIS.
