Some issues with current version of draft-ietf-l2vpn-radius-pe-discovery Good document, but… Narrowly focused, targeted primarily at VPLS Does not take advantage of newly defined RADIUS CoA extensions (RFC3576), instead requiring periodic polling of the RADIUS server to detect changes in provisioning Requires stateful extension to RADIUS servers, e.g., advertising PE identity via attributes in access request messages rather than relying on a centralized configuration database |
