RE: LSA Type 4

Hi Molomo,

You are correct on #2. Type 4 LSAs are used to advertise the location of the
ASBR. But it is most definitely not a summary of Type 5s :)

Hope that helps.

Thanks,

Experts,

I do understand that LSA Type 4 is injected by ABR into a normal area. My
challenge is describing what LSA Type 4 really is.

I have heard of the two explanations below and to me they sound different,

1. LSA Type 4 is a summary of Type 5.
2. LSA Type 4 is an inter area LSA describing who the ASBR(s) in the OSPF
domain are.

Or is it just the language ( English is my second language)?
