Hi, we are planning on replacing individual optical links between 2 of our sites with a couple of 10Gb optical links and than using a LAN switch to carve out that 10Gb into individual links for different environments that require a link between 2 sites. The switches used to host the 10Gb link are 6500's. I can see why a service provider might want to do this for various customers however in this case it just seems that dot1q tunneling will be adding the extra configs and not a lot of benefits.
1. Are there any benefit to using dot1q tunneling in this scenario as opposed to just using normal access vlan's for each link.
2. Are there any restrictions with the type of traffic that can be sent across a dot1q tunnel (mcast etc).
3. Are there any disadvantages to using dot1q in this scenario
I would appreciate any feedback on the above scenario and if anyone has any suggestions besides using MPLS which is not an option at this time. Thx for your help.
