Can I map a single virtual interface (off of a VNF) to multiple physical heth interfaces, for redundancy purposes?
No, this article explains that mapping of a single VNF virtual interface to multiple physical heth interfaces is not supported.
Mapping of a single VNF virtual interface to multiple physical heth interfaces is not supported. JUNOS will only allow mapping of one virtual interface to one physical interface. If you try to configure this, the second config will simply replace the first.
Example:
root@t02-42# show vmhost | display set set vmhost virtualization-options interfaces ge-0/0/0 mapping interface heth-0-4 [edit] root@t02-42# set vmhost virtualiztation-options interfaces ge-0/0/0 mapping interface heth-0-5 [edit] root@t02-42# show vmhost | display set set vmhost virtualization-options interfaces ge-0/0/0 mapping interface heth-0-5
As you can see here, JUNOS will only allow you to configure one virtual interface to a single physical heth interface at one time.
