Routing

How can we chek the advertised to peer by OSPF in JUNOS?

i.e. in case of bgp we use

show route advertised-protocol bgp 1.1.1.1

Your qiuck help will be apprecited.

Hi,

OSPF advertises LSAs. So just check OSPF database for self-created LSAs:

lab@mexico# run show ospf database advertising-router self

    OSPF database, Area 0.0.0.0
 Type       ID               Adv Rtr           Seq      Age  Opt  Cksum  Len
Router  *100.100.100.100  100.100.100.100  0x8000000b   509  0x22 0xbe95  84
Network *10.0.32.1        100.100.100.100  0x80000004   509  0x22 0x83e4  32

If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.

I think only way, we can verify is, by verifying the link state databases of all the routers in that area. If the LSA of a particular router is present in LSDB, then we can assume that router has advertised their networks.

Thanks
