In global zone, a network interface (VNIC) is created on L2 (MAC layer), with unique MAC address.
That is created/assigned to a zone, during zone install/creation or can be done manually as you did in first example.
When using exclusive IP stack, global zone does nothing on IP layer (L3).
So you do not need or require those forwarding options on global zone, or anything really outside vnic definition for zone.
As for your original problem, i presume KVM virtual switch discards everything not coming from assigned interface MAC from options for solaris 11 guest.
For a lab enviroment you can probably a tcpdump or snoop on kvm hypervisor interface and global zone guest, then see if network works in non global zone when dumps are running.
Hope that helps

nbp_name
NBP_NAME(3) Library Functions Manual NBP_NAME(3)
NAME
nbp_name - NBP name parsing
SYNOPSIS
nbp_name( name, obj, type, zone )
char *name, **obj, **type, **zone;
DESCRIPTION
nbp_name() parses user supplied names into their component object, type, and zone. obj, type, and zone should be passed by reference, and
should point to the caller's default values. nbp_name() will change the pointers to the parsed-out values. name is of the form
object:type@zone, where each of object, :type, and @zone replace obj, type, and zone, respectively. type must be proceeded by `:', and
zone must be preceded by `@'.
EXAMPLE
The argument of afpd(8)'s -n option is parsed with nbp_name(). The default value of obj is the first component of the machine's hostname
(as returned by gethostbyname(3)). The default value of type is ``AFPServer'', and of zone is ``*'', the default zone. To cause afpd to
register itself in some zone other than the default, one would invoke it as
afpd -n @some-other-zone
obj and type would retain their default values.
BUGS
obj, type, and zone return pointers into static area which may be over-written on each call.
