Hi all!
We have a maestro with two gateways in active/active mode, on which we are trying to configure receiving routes via bgp from a router.
The router (address 10.20.30.40), with which bgp peering is configured and which advertises a route to the local subnet 10.100.100.0/25.
The command show bgp peers on the gateway gives the following:
CP-01-02> show bgp peers
1_01:
Flags: R - Peer restarted, W - Waiting for End-Of-RIB from Peer
PeerID AS Routes ActRts State InUpds OutUpds Uptime
10.20.30.40 64550 1 0 Established 2 17 01:30:08

PeerID AS Routes ActRts State InUpds OutUpds Uptime
10.20.30.40 64550 0 0 Idle 0 0 00:00:00
The command show route all bgp gives the following:
CP-01-02> show route all bgp
1_01:

It is clear that the route is only on one gateway (which is in the Established state) and the route is Hidden/Inactive.
When trying to figure out why the route doesn't get into active ones, I turned on bgp debugging and the following messages were noticed in /var/log/routed.log:
Jul 9 16:22:46.134988 bgp_rt_import_single_route(7350): Processing route 10.100.100.0/255.255.255.128 for import at Jul 9 16:22:46.134893

I tried to find what the lines has no active route and does not have iBGP sync, marking as unusable mean, but I couldn't find anything on Google. Does anyone know what the problem is and why the route doesn't get into the active ones?
Best regards!
