Cisco IP Transfer Point Xua As Routing Context

1.3.6.1.4.1.9.9.253.1.8.1.1.10

An ASP may be configured to serve more than one AS. In this case, the Routing Context parameter is exchanged between the SG and the ASP, identifying the relevant AS. The Routing Context uniquely identifies the range of traffic associated with a particular AS, which the ASP is configured to receive. There is a 1:1 relationship between a Routing Context value and a Routing Key within an AS.
