SMLT BEB – C-VLAN Guidelines for L2VSN
Customer VLAN (CVLAN) has ISID assigned and is thus L2 extended with L2VSN
On the ERS 8800 and VSP 7000 the CVLAN cannot be configured on any NNI interface
(including the IST)
On the VSP 9000 the CVLAN cannot be configured on any NNI interface (except on the IST
where it MUST be configured)
On the VSP 4000, VSP 7200, and VSP 8000 the CVLAN cannot be configured on any NNI
interface
VSP 4000, VSP 7000, VSP 7200, and VSP 8000 do not support multiple-port NNI MLTs. IS-IS
cannot be enabled on an interface within the MLT.
