A L3 VSN VLAN can also be a L2 VSN VLAN
o
For example, an ISID can be assigned to a VRF for L3 VSN. This does not restrict another
ISID using a different value from the one assigned to the VRF to be assigned to VLANs
within the VRF
ISIS Adjacency
Physical or MLT links between IS-IS switches
Only a single point to point IS-IS adjacency is supported between a pair of IS-IS switches
o
For example, if there are two ports between a pair of IS-IS switches, IS-IS should only be
configured on one of the two ports (if configured on both, only one of those links will form
an IS-IS adjacency)
o
If a single MLT is configured between a pair of IS-IS switches, all ports (1-8) in the MLT will
be utilized – note that the MLT must be configured first and then IS-IS can be enabled on
the MLT
CFM
If not using the simplified CFM configuration commands:
o
The Domain name must be same on all switches in a IS-IS area
o
The Maintenance Association must the same on all switches in a IS-IS area
Two Maintenance Associations should be created, one for each B-VLAN to allow
CFM testing over both B-VLANs
o
The MIP can be configured the same on all switches in a IS-IS area or uniquely defined
per switch
The MEP id should be unique to every switch in the SPB network
The MIP must be configured at the same level as the MEP on all switches in the SPB
network.
