Description

Exist bug with FRR (7.2-0) version in VyOS 1.2.4 when we use Framed-Routes for clients. When we disconnect client session or just reconfigure service pppoe-server, we have undeleted route

[email protected]:~$ show ip route 
...
K>* 172.16.0.0/29 [0/0] is directly connected, unknown, 00:00:27

For reproduce this issue need send via RADIUS attribute Framed-Route.
In 1.3-rolling-202001120217 FRR (7.3-dev-20191226-00-gd7cce42cc-0) - all works as expected and Framed-Routes deleted correct.

The described problem exists in stable FRR 7.2, but fixed in FRR master branch by https://github.com/FRRouting/frr/pull/5184
We have tested 7.2 with this PR applied, and the bug was gone, so we can apply this PR to our FRR package and solve the problem.
