Release Information
Statement introduced in Junos OS Release 12.3.
Description
Configures make before break (MBB) for multicast LDP (MLDP) link protection to ensure minimum packet loss when attempting to signal a new label-switched path (LSP) before tearing down the old LSP path.
Options
timeout seconds | — | Specify a value to change a make -before-break timeout for point-to-multipoint LSPs. Even if an MBB acknowledgment is not received for a point-to-multipoint LSP before the specified timeout period expires, the label-switching router (LSR) performs an MBB switchover from the old LSR to the new upstream LSR. |
Range: 1 through 300 seconds
Default: 30 seconds
switchover-delay seconds | — | Specify a value to change switchover delay for a point-to-multipoint LSP from the old LSR to the new upstream LSR. If an MBB acknowledgment is received on a point of local repair (PLR) router, the PLR waits for the specified seconds to switch its upstream LSR from the old LSR to the new LSR. |
Range: 1 through 300 seconds
Default: 30 seconds
