17-38 Riverstone Networks RS Switch Router User Guide Release 8.0
Configuring L3 Label Switched Paths MPLS Configuration
operates in standby mode. Both paths are configured to be adaptive; that is, during route recalculation, the LSP waits
until the new optimized route is set up before tearing down the previous LSP. In this example, RSVP is the signaling
protocol used (LDP can also be used, as traffic engineering is not being utilized).
Additionally, a dynamic LSP will be configured from RS router R5 to the router JN1 and another from R6 to R7. These
LSPs are also configured to be adaptive.
OSPF is the routing protocol that is used on all RS routers.
