I was wondering whether someone did migrate from a standard 802.1q tagged core like Cisco to a Fabric SPBM with VSP 7400 series and would like to share their lessons learned.
Cisco 4500x cores -- X460G2-10GE4 (distribution / edge)
VSP 7000 -- X460G2-10GE4 (fabric attach)
Options I can think of:
VSP 7400 --- Cisco 4500x
- not sure how to have 802.1q tagging between VSP 7400 and Cisco 4500x and SPBM at the same time
- Migrate all X460G2 from Cisco 4500x to VSP7400
VSP 7400 --- x460G2-10GE4 --- Cisco 4500x
- the x460G2 would be a fabric attached client on the VSP7400 side and a standard 802.1q trunking client on the Cisco 4500x side.
- migrate all remaining X460G2s to the VSP7400 as fabric attached units
