Bundle Ethernet
Introduction
ARS9k allow for bundling of interfaces into one logical interface. Ethernet and POS interfaces can be bundled. This document provides overview of the Ethernet bundling.
Bundle Ethernet
- Cisco's other platform call it Etherchannel or Port-channel.
- Bundle-Ethernet is the interface used for bundling Ethernet interfaces at the ASR9K platform.
- Each bundle can have at minimum one link and maximum of 64 links.
- Each bundle has one MAC address, one IP address and these QoS and ACL configuration for all the member links.
- Layer 2 and Layer 3 bundles are supported.
- Release 4.0.0 started support for MLAG.
- Release 5.1.2 started the support for mix speed bundle members.
- Two methods of configuring it, LACP and Cisco proprietary (does not provide any misconfiguration detection as LACP does).
- Bundles can span across line cards and chassis (using MLAG).
- CDP works independently of each link.
- Bundle MAC addresses in the Cisco ASR 9000 Series Router come from a set of reserved MAC addresses in the backplane.
Configuration
- Basic configuration of an Bundle-Ethernet:
- Create the logical bundle-ether interface.
- Configure the bundle-ether interface with IP and subnet.
- Add link interfaces to the bundle with bundle-id (number) command.
- Basic configuration Example:
- Optional Features
- VLAN Bundles
