Hi Bence:
Exactly, the Neutron router (that will be connected to one of those segments), will not provide any routing between the segments/subnets CIDRs. But the packets coming out from this Neutron router to the external router should point to the GW IP.
In the example provided: there are two segments, each one with a subnet. The router is connected to the first segment and has connectivity to subnet 1 CIDR (10.46.54.0/26). The GW IP for this subnet is 10.46.54.62. The route installed in the router namespace routing table (sorry for the alliteration), is in charge of sending the packets with destination to the subnet 2 CIDR out of the router namespace. But those packets should have, as destination MAC address, the GW IP device MAC address. That means the following route:
# 10.46.54.64/26 dev qg-7847fd00-72 proto static scope link
should be:
# 10.46.54.64/26 dev qg-7847fd00-72 via 10.46.54.62 proto static scope link
Regards.
