pppoe-server framed-routes not deleted from routing table
In progress, Requires assessmentPublicBUG


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

vyos@BRAS:~$ show ip route 
K>* [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.
