1.3-rolling use FRR with commit d7cce42cc78cfbe25e3cc19a612b1caee3c26809
So I test FRR stable 7.2 in Ubuntu 18.04 (FRR official build), it works fine
test FRR d7cce42cc in Ubuntu 18.04, it fails
test FRR branch dev/7.3 which is 4112bfee9f6abf8832d1f8cf9a7e4df9b29ef764 in Ubuntu 18.04, it works
I think FRR in vyos need to be upgraded to new version
