Use the following CLI syntax to create an SDP and select an encapsulation type. If gre or mpls is not specified, the default encapsulation type is gre.
When specifying MPLS SDP parameters, specify an LSP or enable LDP. There cannot be two methods of transport in a single SDP except if the mixed-lsp command is specified. If an LSP name is specified, then RSVP is used for dynamic signaling within the LSP.
LSPs are configured in the config>router>mpls context. See the 7450 ESS, 7750 SR, 7950 XRS, and VSR MPLS Guide MPLS Configuration Guide for configuration and command information.
Use the following CLI syntax to create a GRE SDP or an MPLS SDP:
config>service>sdp sdp-id [gre | mpls] create
— adv-mtu-override
— description description-string
— far-end ip-address
— keep-alive
— hello-time seconds
— hold-down-time seconds
— max-drop-count count
— message-length octets
— timeout timeout
— no shutdown
— ldp (only for MPLS SDPs)
— lsp lsp-name [lsp-name] (only for MPLS SDPs)
— path-mtu octets
— signaling {off | tldp}
— no shutdown
The following displays an example of a GRE SDP, an LSP-signaled MPLS SDP, and an LDP-signaled MPLS SDP configuration.
