PE router when forming a MC-LAG instance. Each PE router needs a
Answer: A,B. The
mc-ae-id has two purposes: glue together
MC-LAG interfaces across different PE routers and uniquely identify
different logical MC-LAG interfaces. For example, if
CE1 was connected to
mc-ae-id would be 1. If
CE2 was connected to
mc-ae-id would be 2.
Answer: A,B,D. Redundancy groups are a collection of MC-AE IDs that share the same VLAN IDs. Redundancy groups act as a broadcast medium between PE routers so that application messages are concise and efficient. In this example, the application would be MAC address updates.
Answer: A. Only MC-LAG in
active-active mode requires an ICL.
The ICL is used as a Layer 2 link between the two PE routers so that
as frames arrive from the CE, both the PE routers can handle the
