[Bug 1797037] [NEW] Extra routes configured on routers are not set in the router namespace and snat namespace with DVR-HA routers

 

Public bug reported:

When DVR routers are configured for HA and if we try to add an extra
route to the DVR routers, the extra route is not set in the router
namespace or in the snat namespace.

Configure for HA and DVR
1. Create Router
2. Attach Interface
3. Try to add an extra route with destination and nexthop.
4. You can see the routes in the router dict, but it is missing in the router namespace on the 'dvr-snat' node.
The routes are handled properly on the compute nodes that are running as 'dvr' or 'dvr_no_external' agent modes.
