Command History
Usage Guidelines Use this command to set the affinity and affinity mask values for an LSP in an LSP attribute list.
The affinity value determines the attribute flags for links that make up the LSP, either 0 or 1. The attribute
m
ask determines which attribute value the router should check. If a bit in the mask is 0, an attribute value
of a link or that bit is irrelevant. If a bit in the mask is 1, the attribute value of a link and the required
affinity of the LSP for that bit must match.
An LSP can use a link if the link affinity equals the attribute flag value and the affinity mask value.
Any value set to 1 in the affinity should also be set to 1 in the mask.
To associate the LSP affinity attribute and the LSP attribute list with a path option for an LSP, you must
co
nfigure the tunnel mpls traffic-eng path option command with the attributes string keyword and
argument, where string is the identifier for the specific LSP attribute list.

mask va
lue (Optional) Indicates which attribute values should be checked. If a bit in the
mask is 0, an attribute value of the link or that bit is irrelevant. If a bit in the
mask is 1, the attribute value of that link and the required affinity of the
tunnel for that bit must match.
