Type 4 sla is "where to go" for the next hop of the type 5 sla.  So they are 
both related and must cross the area boundary together.

Subject: [OSL | CCIE_RS] LSA's allowed



Hi,

  According to most Cisco documentation, a stub area wont allow type 5 
LSA's, but will still allow type 4 (ASBR summary). In some Cisco press 
material, its stated that both type 4 and 5 LSA's are blocked in a stub 
area.

  My own labs show that both type 4 and 5's are removed from the OSPF 
database upon making it a stub area. My concern is, whether the type 4 
is actually received, but since the type 5 is not there, it just 
discards it anyways?

  Hope someone can give some input regarding theory-behavior Vs. 
real-life behavior...

  Thanks!

Sincerely,
Kim Pedersen
