DCI: simple extend layer 2 data center less than 4000 VLAN ? (Choose Two)
A.
OTV
B.
VXLAN
C.
LISP
D.
MPLS
E.
L2TP
Explanation:
MPLS using AToM or VPLS I guess..
VXLAN could do it but I think they would have not specified “<4000 vlans” if they wanted us to answer that.
In fact, we could even think of L2TPv3…
Even if it’s really dirty, it’s possible(https://www.cisco.com/c/en/us/td/docs/ios/12_0s/feature/guide/l2tpv30s.html#wp1027175 “For L2TPv3, an Ethernet subinterface configured to support VLAN
switching may be bound to an Xconnect service so that all Ethernet traffic, tagged with a VID specified on the subinterface, is tunneled to another PE.”)
