Shared Risk Link
Groups
(SONET/SDH layer rates only) Free-format string that represents the shared risk link group
(SRLG), or a group of links that share a common risk. For example, a set of links that originate at a
node share the node as the common risk.
SRLGs allow you to classify links into logical groups. By grouping the links, you can specify
diverse link routing for a circuit. That is, if the circuit is fully protected, it is routed on the working
and protect paths with a diverse SRLG attribute.
The Shared Risk Link Groups field supports up to 5 comma-separated values, with 32 characters per
value.
