Record route is enabled by default.
MPLS router MPLS interface dynamic bypass configuration mode (config-router-mpls-if-ethernet-slot/port-dynamic-bypass).
Based on the value of the parameter, dynamic bypass LSPs create with their record-route option enabled or disabled.
MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.
The following example enables record-route on the dynamic bypass MPLS Ethernet interface 0/8 .
device>configure device(config)# router mpls device(config-router-mpls)# mpls-interface ethernet 0/8 device(config-router-mpls-if-ethernet-0/8)# dynamic-bypass device(config-router-mpls-if-ethernet-0/8-dynamic-bypass)# record-route enable
