Configuring EVPN Ethernet Segment
Step 6
force single-homed
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac-es)# force single-homed
Specifies forced attributes for this Ethernet Segment.
Step 7 identifier type esi-type esi-identifier
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac-es)# identifier type 0 ce.01.ce.01.ce.01.ce.01.01
Configures the Ethernet segment identifier (ESI) of an interface.
Step 8
bgp route-target ipv4/v6-address
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac-es)# bgp route-target ce01.ce01.ce01
Configures the BGP Import Route-Target for the Ethernet-Segment.
This command configuration is mandatory for ESI type 0.
Note
Step 9 load-balancing-mode per-service
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac-es)# load-balancing-mode per-service
Specifies the load balancing mode.
Step 10
service-carving manual primary {isid} secondary {isid}
Example:
RP/0/RSP0/CPU0:router(config-evpn-ac-es)# service-carving manual primary 100 secondary 200
Specifies a list of service identifiers (isid) as active and standby services. The isid range is from 256 to 16777216.
Step 11 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
