Problem reported with cross-vrf static routes that the routes weren't installed when the target interface is bounced. Determined that we did not initiate re-install of the statics in that particular case, so added it. Test case previously failing now passes. Signed-off-by: Don Slice <dslice@cumulusnetworks.com>
