Refer to the exhibit. Why is a route leaking mechanism needed in this large, unified MPLS network with end-to-end BGP labeled prefixes and IS-IS multilevel areas as the IGP?
A) for PE management such as Telnet or SNMP
B) to leak routes from the Layer 2 backbone to the Layer 1 areas
C) to build an LSP between the PE routers
D) to announce PE loopbacks fromother IS-IS areas into the Layer 2 backbone area
