When a Router receives a BGP UPDATE packet that contains Network Layer Reachability Information (NLRI) – this is, a route; the packet is processed in the next order: – Step 1. BGP checks for the NLRI (prefix received) against any BGP inbound filter configured on the Router. – Step 2. If the NLRI is not… Read More »

OSMC KODI: Mount NFS using fstab

Why use /etc/fstab instead of Kodi’s built in NFS client? Using /etc/fstab is faster than Kodi’s own NFS client – it delivers better throughput and is more reliable (also than SMB mounting). Many performance issues, especially with high-bitrate content can be solved by using NFS shares and /etc/fstab. Additionally, it’s quite easy to set up.… Read More »

BGP Aggregate experiment

The BGP aggregate-address can be used to summarise a set of networks into a single prefix. For this post, I just wanted to show the difference between aggregate-address and aggregate-address with summary only. We have below topology. I’m going to summarise prefixes in R1. R1 config hostname R1 ! interface GigabitEthernet0/0 ip address 10.10.10.1 255.255.255.252… Read More »
