We are working on blocking communication within the same VLAN, so two hosts on the same VLAN will not be able to communicate with each other. I know we can do a Layer2 host block via AP but this is more from the switch. We have many access points (AP...

In my lab setup, I have the following connections: (R1)---eBGP----(R2)----iBGP---(R3)R1 advertises the IP address 1.1.1.1 to R2 via eBGP. R2 then forwards 1.1.1.1 to R3 using iBGP, with the next-hop-self attribute configured on R2.However, I've notic...

I understand VLAN creates a broadcast domain and L2 switch only fwd within the VLAN without an L3 device. However, how does the L2 switch knows which VLAN the frame needs to go without a dot1q Header? For eg. I did a pcap and I don't see any VLAN ID ...

So LO 5.5.5.5 is config in both B and D?--> correct. If Yes then ibgp will prefer than ebgp' --> If that's the case then why does the Best path selection state "eBGP over iBGP". If iBGP doesn't add AS(which makes sense) so Shortest AS path will alwa...

Then RouterA have two path with same AS-PATH and hence here we can prefer ebgp over ibgp.--> Correct. This is similar to what I was playing with. However in my case iBGP is preferred over eBGP. Router A connects to Router B via eBGPRouter A also conn...

I thought there wouldn't be any AS-Path on iBGP. i.e AS_PATH for iBGP should be empty. If that's the case then iBGP will always be preferred over eBGP by default.
