Hello, In section 4.3.7 Non support of ERO in Rsvp-Lsp-Tunnel-07 draft, it is said that An RSVP router that does not recognize the EXPLICIT_ROUTE object sends a PathErr with the error code "Unknown object class" toward the sender. This causes the path setup to fail. The sender should notify management that a LSP cannot be established and possibly take action to continue the reservation without the EXPLICIT_ROUTE or via a different explicit route. My question is how the sender knows that the intermediate node does not support ERO object alone and support other TE objects such as RSVP-TE session, Label Request Object etc. The sender once it receives "Unknown Object class", if my assumption is right it has to assume that the intermediate node supports only RSVP and not RSVP-TE. Hence it will try to establish a path via a different explicit route and not through the same intermediate node without an ERO, unless otherwise it is sure of the behavior of the node. I think the statement underlined can be removed, else there is any specific purpose for keeping the above statement. Any reply from authors.
