ospf lsa question

[hothotstreet]

I have a frr host, I added two of the interfaces to vrf, and announced the two interfaces in the ospf of vrf, but when I checked the database of ospf, I found that two lsa representing my frr host appeared in the type 1 lsa ,How is this going?

ospf configuration:
router ospf vrf vrf_20002_4
redistribute bgp
network 10.251.0.0/16 area 0
network 10.254.0.0/16 area 0

That column is Link Count. Show ip ospf database shows each lsa type in it's own section Router Link States, Net Link States...

sorry,look at this picture,The first line of data of the network lsa,the interface ip address 10.251.0.1 10.251.0.1 is this the same host ,So this network lsa should be abnormal

Can you show your complete configuration? in particular IP addresses assigned to the various interface? and also the resut of show ip ospf neighbor?

Regarding LSA type 1 announced by OSPF, it depends of the network ... CLI. Here, you setup 2 network for respectively 10.251/16 and 10.254/16, so that, it is normal that OSPF announce these 2 subnets if there is interfaces that belongs to them.

10.254.0.1 IP is configured on some other router with router-id as 10.254.0.1. This is received LSA. You can check if the same IP is configured somewhere else as well. You can see the advertising router-id field.
