Selecting specific router only shows routes from a single BMP session #18
Description
In our setup, we utilize Nokia routers within an MPLS network configuration. This necessitates configuring BMP sessions from our Internet VRF for EBGP routes and on our Base router for IBGP (VPN) routes. Our routers establish two separate BMP sessions originating from the same IP address but using different source ports. This setup leads to a problem with fernglas, specifically when selecting a single router in the frontend. In this scenario, only the routes from one of the two BMP sessions are displayed. However, when selecting "on all", all routes are shown correctly.
Excepted behavior
When selecting a single router in the frontend, I expect to see all routes known by this particular router, irrespective of the BMP session source port.
Observed behavior
When selecting a single router in the frontend, only the routes from one of the BMP sessions are displayed, leading to incomplete data.
