I have the below topology set up in GNS3 running OSPF. R8 and R1 are ABRs, Area 0 is on on the left and Area 1 is on the right. R3, R4, and R5 are redistributing some loopback interfaces into Area 0. When I run show ip ospf database asbr-summary on E...

Thank you, I have cleared the ospf process and also fully rebooted all routers in this topology. I can only assume at this point that this may be a bug in the IOS, likely cosmetic. Since we can reach R1 from R8 within area 1, and also see it's Type 1...

Hi Giuseppe, Thank you for that explanation. I have one more question regarding the reachability of the router based on RID. My understanding is that OSPF algorithm is recursive, so even though the RID of 0.0.0.8 is not a reachable IP, the router wou...

Thanks Mike, I think I understand the order of operations, but I'm trying to figure out if there is a discrepancy in the guide I'm reading, since it it proposing to make a 443 blacklist ACE in the ACP before the application detection ACE for allowing...
