Configuring ANCP for Backward Compatibility
You can configure ANCP to operate in a mode compatible with the protocol as it was initially proposed to operate. This backward-compatible or pre-IETF mode is compatible with Internet draft draft-wadhwa-gsmp-l2control-configuration-00.txt, GSMP extensions for layer2 control (L2C). Setting this backward-compatible mode enables interoperation with devices that are not compatible with the later ANCP Internet drafts or RFC 6320, Protocol for Access Node Control Mechanism in Broadband Networks.
When this mode is configured globally for all neighbors, you can override it for a particular neighbor that supports the IETF draft or standard.
To configure the ANCP agent to operate in a backward-compatible mode for all neighbors:
- Specify the pre-IETF mode.[edit protocols ancp]user@host# set pre-ietf-mode
To configure the ANCP agent to operate in a backward-compatible mode for a specific neighbor:
- Specify the pre-IETF mode.[edit protocols ancp neighbor 10.2.3.4]user@host# set pre-ietf-mode
- To override the globally configured backward-compatible
mode for a specific neighbor:
Specify the IETF mode.
[edit protocols ancp neighbor 10.2.3.4]user@host# set ietf-mode
