Neet to interconnect 2 datacenter (extend the Layer2) with 2 indipendent 1Gbps links (total available 2Gbps) and the requirements are:
- use 4 switches for HA (2 switches on both datacenters with each the 1Gbps link );
- transport between the 2 datacenter many ethernet 802.1q VLANs (layer 2 frame 1522 bytes);
- use all the band. available.
As solution is it possible to use/configure Multi-Chassis EtherChannel to aggregate the 2 links (or are available other feature to aggregate the 2 links)?
On which cisco platform is Multi-Chassis EtherChannel available ?
Any other solution (i know i can use spanning-tree and configure VLAN odd to the 1st link and VLAN even on the other) ?
Thanks to all.
