As a result, all LSPsusing the sessions will be deleted.z Usually, you do not need to configure the LDP LSR ID, which defaults to the MPLS LSR ID. Insome VPN applications (for example, MPLS L3VPN applications), however, you need to ensurethat different LDP instances have different LDP LSR IDs if the address spaces overlap. Otherwise,the TCP connections cannot be established normally.Configuring Local LDP Session ParametersYou can configure a local session transport address to be the IP address of an interface or a specified IPaddress.Follow these steps to configure local LDP session parameters:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Set the link Hello timer mpls ldp timer hello-holdvalueOptional15 seconds by defaultSet the link Keepalive timer mpls ldp timerkeepalive-hold valueOptional45 seconds by default
