GRE in a fib via rc.conf

All
  I am looking for some help on if my setup makes sense.
I have a vm with two interfaces. One for access to the host , we'll call
this mgmt . One for routing traffic, we'll call this routing . I want to
put the routing interface into a fib and to run a gre tunnel over it.
Sounds simple enough.  The problem I am seeing is that it looks like the
tunneled traffic is leaked into the default fib and I don't see why. I am
not sure if this is config nit or if this is an issue. Should the gre10
interface be in fib 1 ?  See below.

### RC CONF ###
ifconfig_vmx0="inet 10.23.121.253/24 description mgmt"
ifconfig_vmx1="inet 100.65.101.14/28 mtu 9000 description routing fib 1"
defaultrouter="10.23.121.1"

# setfib 0 ping -c 1 -t 2 100.67.103.1
PING 100.67.103.1 (100.67.103.1): 56 data bytes

round-trip min/avg/max/stddev = 1.528/1.528/1.528/0.000 ms

#### TCPDUMP ####
ICMP packets are in fact sourced from the gre10 interface.
The GRE packets are also only going out the routing interface.
