Manual Summarization with BGP on Cisco Routers

March 22, 2018 at 8:57 pm

BGP

One of the topics that will be featured in my upcoming CBT Nuggets module, Border Gateway Protocol (BGP) – Advertising NLRI, manual route summarization in BGP. This post serves (as well as more to follow) cover the highlights of the video coverage.

There are two methods of performing aggregation with BGP on a Cisco router. You can create a static route that represents the aggregate and then advertise that route using the network command. Or, you can use the aggregate-address command.

Here is an example of the static route approach:

router bgp 65100
   network 192.168.192.0 mask 255.255.248.0
   neighbor 192.168.1.220 remote-as 65200
!
ip classless
ip route 192.168.192.0 255.255.248.0 Null0

Notice how the static route directs to the bit bucket (Null0). This is because it is not an actual network destination. It is an artificial construct to permit the route in the routing table so we can use the network command in BGP. There will be more specific entries in the routing table covered by this advertised summary and the router can follow those instructions. Should all the more specific entries be removed, then the static route has traffic discarded for the summary (this is the desired behavior, typically).

With the aggregate-address command approach, you ensure component routes of the summary exist in the BGP table (thanks to the network statement or redistribution), and the summary address is advertised via BGP. Here is an example:

router bgp 65100
 aggregate-address 192.168.192.0 255.255.248.0 summary-only
 redistribute eigrp 100
 neighbor 192.168.1.220 remote-as 65200

Note that if you forget the summary-only keyword with the aggregate-address command, you will advertise the summary as well as the specific routes. A future post will demonstrate when this approach might be useful.

Say Goodbye to the Windows 10 HomeGroup Feature

March 19, 2018 at 7:02 pm

Last night (3/18/2018) I downloaded and installed the latest Preview Build of the upcoming Windows 10 Spring 2018 Update and discovered that Microsoft is killing the HomeGroup feature of Windows 10. That’s right, even if you are currently running it in your latest production builds – it will be stripped from your systems when you move to the next major update of Windows 10 in the Spring of 2018.

At least that is currently what is set to happen per Microsoft. Of course, there is time for this to change (think the canceled destruction of the classic Paint app). I really doubt Microsoft will change their mind on this one, however.

What does Microsoft want Windows 10 users to do instead of relying on the HomeGroup features? Well, the answer is clear – they want you to use OneDrive for your sharing needs, and for whatever that cannot handle, they want you to use the Sharing functionality in the various network object properties.

NOTE: For those of my readers preparing for MCSA Certification in Windows 10, remember, HomeGroup is NOT dead as far as the current exams are concerned. The topics for HomeGroup are still alive and well in the exam objectives and the actual exams themselves. It will not be until the Windows 10 Exam refreshes will we see the end of HomeGroup from a certification perspective.
