[NETVIRT-1390] Extra route not removed on dc-gw on router-update --no-routes

Wed, 27 Nov 2019 05:30:40 +0000

Test Case:

========

->Configure BGP neighbor.

->configure 8 networks , 16 VMs . all 8 networks attached to router R1.

->configure vpn instance with 8 rds and associate router R1.

->configure ipv4 and ipv6 extra route with 8 VMs one in each network as next hop.Check fib and dcgw for route propagation

->remove the extra route configuration using router update --no-routes option.

->Check fib, bgp deamon and dcgw and compute.

Issue: After router update --no-routes, the ipv6 extra route is not removed from bgp deamon , dc-gw and from table 21 flow entries in computes.

Prefix which is not removed 2111:12f:862:18::/64. Attaching issue description which has more info on this.
