Link aggregation, LAG, Bundle, EtherChannel, what ever you say, they have the same logic in real. So, the configuration logic of Link Aggregation (LAG) is not different than Ether Channel logic on Cisco devices that run Cisco XR software. Here, again the bundle is created and the ports are made to join to this bundle. And the same bundle members become like a single link together.
We will use the basic topology includes two ASR 9010 series like below.
Let’s see Link Aggragation (LAG) configuration on Cisco XR step by step. Here, I will use Cisco ASR 9010 series for the configuration.
1. Firstly, let’s create a bundle on our router ASR 9010.
Here, our bundle type is Ethernet, because we want to aggregate Ethernet links. We are adding an optional description to our bundle and we are entering the mtu value. This mtu value can be given according to your companies values. We are configuring the minimum active links that means that if there are less links than this value, then bundle will be down. Lastly, we are adding load interval value as 30 seconds. This value is load calculation interval value.
2. Now, it is time to add intetfaces, under this Bundle.
