Cisco ASR 9000 Series

Configuring BGP Route Target
By default, these parameters are auto-derived from the PE's configuration:
• Route Distinguisher (RD) for global Ethernet Segment table
Default: Auto-generated RD based on loopback IP address
• EVI’s BGP Route Distinguisher (RD)
Default: Auto-generated RD based on loopback IP address
• EVI’s BGP Route Target. Default: Auto-generated RT based on EVI ID
Perform this task to overwrite the auto-generated BGP RD/RT values.
