Bug 8609 - CSIT Sporadic failures - vpnservice suite - l3 rule leftover in
table=19

A router interface reference in a VPN will have to be removed before the
host interface references for that subnet in the VPN are removed. This is
to ensure that the FIB Entry of the router interface is not the last entry
to be removed for that subnet in the VPN.
If router interface FIB entry is the last to be removed for a subnet in a
VPN , then all the host interface references in the vpn will already have
been cleared, which will cause failures in cleanup of router interface
flows.
