The present invention relates to an ingress node () and methods therein for Operation Administration arid Maintenance, OAM related to Resource Reservation Protocol-Traffic Engineering, RSVP-TE5 for obtaining attributes for timer values being assigned to a connection from the ingress node () via intermediate nodes () to an egress node (), during configuration of die connection. An interval of suitable tinier values for the intermediate nodes is specified. Configuration attributes are obtained for a timer value within an interval that is acceptable by the intermediate nodes and the egress node, based on the specified interval of suitable timer values. The obtained configuration attributes are applied during configuration of the connection from the ingress node via the intermediate nodes to the egress node, if the obtained configuration attributes are appropriate to the ingress node. Fine-tuning of connection related timers can therefore be achieved, decreasing the overall recovery time and the overall overhead. 1.
