Diameter:Difference between Vendor-Id presents as an independent AVP and within the Vendor-Specific-Application-ID AVP ?

+3 votes

I saw Capabilities-Exchange-Request and Capabilities-Exchange-Answer messages. In CER message there are two places where Vendor-Id AVP is present, one as an independent AVP and the other one as part of Vendor-Specific-Application-Id AVP. If both of them are present in request message then both will be having same value or can hold different values.

Both will contain the same value (val=10415).

After establishing the transport connection, the PCRF and the AF shall advertise the support of the Rx specific Application by including the value of the application identifier in the Auth-Application-Id AVP and the value of the 3GPP (10415) in the Vendor-Id AVP of the Vendor-Specific-Application-Id AVP contained in the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands.

Refer the below specs for more clarity.

1.3GPP TS 29.214 version 7.4.0 Release 7

2.RFC 3588

Also what are the rules for populating those AVPs (in the RFC it is not clear when to use each one of the option)?

What is the use of keeping the same information in two places like Application-Id in the Diameter header and Application-Id as AVP ?

In that case, how does a Diameter node make out whether its peer Diameter Agent node works as a Diameter Relay or works as a Diameter Re-direct node ?
Is it pre-configured in the Diameter node or by exchanging some Diameter messages that role is decided ?
