A. The IRB sub-interface must be configured as either type bridge or routed.
B. A MAC-VRF can be configured with multiple IRB sub-interfaces to support multi-homing.
C. When the IRB sub-interface is configured with multiple IP addresses, one of them can be configured as the primary.
D. When using an IRB interface to interconnect a MAC-VRF to an IP-VRF, one sub-interface is configured for the MAC-VRF and another one for the IP-VR
Question#2
Which of the following is NOT part of the description of a BGP route-distinguisher?
A. The route-distinguisher is a unique identifier that is configured per PE and per EV
B. It is included in each EVPN route update advertisement.
C. It is used by MP-BGP to allow for overlapping addresses from multiple tenants.
