Join Chris Bryant for an in-depth discussion in this video Passive and nonpassive interfaces, part of CCNP Troubleshooting (300-135) Cert Prep.
- [Narrator] This is a little feature in OSPF…that can really come in handy,…and I don't think this is going to apply…to anyone out there today, but back in my time,…I remember people having arguments about whether…there was such a thing as an OSPF passive interface.…So, that's one reason we're talking about it…is to let you know that, yes, there is such a thing…as an OSPF passive interface,…and you're going to see it in action.…Not a ton of troubleshooting to it but hang in there…if you're familiar with it because we're going to do…a little bit of t-shooting with it.…You're going to see what happens when it goes wrong,…and a little bonus dad lecture at the end…at no additional charge, but first off,…we're going to come in near the end of this lab…because I've got everything built here except…for that FastEthernet0/1 interface 184.108.40.206.…
I have the 220.127.116.11/24 subnet working there…but that particular interface in this lab is not leading…to any potential OSPF neighbors.…We do, however, want to advertise 18.104.22.168/24…
