DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide Parameter UDP Port Max PDU Length Initial Backoff Max Backoff Transport Address Keep-Alive Time Link Hello Interval Link Hello Hold Time Hello Source Address Type Description In this field the LDP UDP port number will be displayed. In this field the LDP maximum PDU length value will be displayed. Enter the initial back-off delay time here. The LDP back-off delay time is a mechanism to prevent an endless sequence of session setup failures that occur between two LSRs with incompatible settings. The range is from 15 to 65535 seconds. Select the Default option to use the default value, which is 15 seconds. Enter the maximum back-off delay time here. The range is from 120 to 65535 seconds. Select the Default option to use the default value, which is 600 seconds. Enter the transport IPv4 address here. The transport address is used to establish a LDP TCP connection. Select the Default option to use the default setting. Selecting the Interface option specifies to use the IP address of the corresponding interface as the transmission address for the session on each interface. Enter the keep-alive time value here. LDP maintains a keep-alive hold timer for each peer session. If the keep-alive hold timer expires without receipt of an LDP PDU from the peer, LDP terminates the LDP session. The range is from 15 to 65535 seconds. Select the Default option to use the default value, which is 40 seconds. Enter the link hello interval value here. The range is from 1 to 65535 seconds. Select the Default option to use the default value, which is 5 seconds. Enter the link hello hold time value here. The range is from 5 to 65535 seconds. Select the Default option to use the default value, which is 15 seconds. Select the source address type of the hello packet here. Options to choose from are: • Interface - Specifies that the IP address of each interface is used as the hello source address. • Router ID - Specifies that the LSR ID (router ID) will be used as the hello source address. • IP Address - Specifies to manually enter the IP address used as the hello source address. Hello Source Address Distribution Method LSP Control Mode Enter the IP address that will be used as the hello source address here. Select the distribution method here. Options to choose from are: • DU - Specifies the downstream unsolicited distribution mode. • DoD - Specifies the downstream on-demand distribution mode. If the mode is configured as Downstream-on-Demand mode, the downstream LSR advertises a label mapping when an upstream connection makes an explicit request. If the mode is configured as Downstream-Unsolicited mode, the downstream LSR advertises a label mapping when a label is learned in the routing table. Select the Default option to use the default setting, which is DU. Select the Label-Switched Path (LSP) control mode here. Options to choose from are Independent and Ordered. In Independent LSP Control mode, each LSR independently binds a label to a Forwarding Equivalence Class (FEC) and distributes the binding to its label distribution peers. In Ordered LSP Control mode, an LSR only binds a label to a FEC if it is the egress LSR for that FEC, or if it has already received a label binding for that FEC from its next hop for that FEC. Select the Default option to use the default setting, which is Independent. 596
