Configuring Tcn Propagation - Cisco ASR 9000 Series Configuration Manuallines

Implementing Multipoint Layer 2 Services
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp-port0)# exit
Exits port0 configuration submode.
Step 7
port1 { interface type interface-path-id | virtual | none}
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp)# port1 interface GigabitEthernet 0/1/0/8
Enables G.8032 ERP for the specified port (ring port).
Step 8 monitor port1 interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp-port1)# monitor port1 interface 0/1/0/3
Specifies the port that is monitored to detect ring link failure per ring port. The monitored interface must be a sub-interface
of the main interface.
Step 9 exit
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp-port1)# exit
Exits port1 configuration submode.
Step 10
exclusion-list vlan-ids vlan-id
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp)# exclusion-list vlan-ids a-d
Specifies a set of VLAN IDs that is not protected by Ethernet ring protection mechanism.
Step 11 open-ring
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-erp)# open-ring
Specifies Ethernet ring G.8032 as open ring.
Step 12
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.
