Field

 

Description

 

 

Shared Risk Link

(SONET/SDH layer rates only) Free-format string that represents the shared risk link group

Groups

 

(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.
