SDP Commands
Page 104 7210 SAS-X, R6 OS Services Guide
If the SDP uses MPLS encapsulation, the far-end ip-address is used to check LSP names when added
to the SDP. If the “to IP address” defined within the LSP configuration does not exactly match the
SDP far-end ip-address, the LSP will not be added to the SDP and an error will be generated.
Alternatively, and SDP that uses MPLS can have an MPLS-TP node with an MPLS-TP node-id and
(optioanlly) global-id. In this case, the SDP must use an MPLS-TP LSP and the SDP signaling
parameter must be set to off.
An SDP cannot be administratively enabled until a far-end ip-address or MPLS-TP node-id is
defined. The SDP is operational when it is administratively enabled (no shutdown) and the far-end ip-
address is contained in the IGP routing table as a host route. OSPF ABRs should not summarize host
routes between areas. This can cause SDPs to become operationally down. Static host routes (direct
and indirect) can be defined in the local dev ice to alleviate this issue.
The no form of this command removes the currently configured destination IP address for the SDP.
The ip-address parameter is not specified and will generate an error if used in the no far-end
command. The SDP must be administratively disabled using the config service sdp shutdown
command before the no far-end command can be executed. Removing the far end IP address will
cause all lsp-name associations with the SDP to be removed.
Default none
Parameters ip-address — The system address of the far-end 7210 SAS-M and SAS-X for the SDP in dotted
decimal notation.
node-id node-id — The MPLS-TP Node ID of the far-end system for the SDP, either in dotted
decimal notaion (a.b.c.d) or an unsigned 32-bit integer (1 – 4294967295). This parameter is
mandatory for an SDP using an MPLS-TP LSP.
global-id global-id — The MPLS-TP Global ID of the far-end system for the SDP, in an unsigned 32-
bit integer (0 – 4294967295). This parameter is optonal for an SDP using an MPLS-TP LSP. If
note entered, a default value for the Global ID of ‘0’ is used. A global ID of ‘0’ indicates that the
far end node is in the same domain as the local node. The user must explicitly configure a Global
ID if its value is non-zero.

Context config>service>sdp
Description This command specifies the metric to be used within the tunnel table manager for decision making
purposes. When multiple SDPs going to the same destination exist, this value is used as a tie-breaker
by tunnel table manager users such as MP-BGP to select the route with the lower value.
Parameters metric — Specifies the SDP metric.
Values 0 — 65535
