RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-vfi)#
Configures the virtual forwarding interface (VFI) parameters and enters L2VPN bridge group bridge domain VFI
configuration mode.
• Use the vfi-name argument to configure the name of the specified virtual forwarding interface.
Step 6
exit
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-vfi)# exit
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd)#
Exits the current configuration mode.
Step 7
neighbor { A.B.C.D } { pw-id value }
Example:
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd)# neighbor 10.1.1.2 pw-id 1000
RP/0/RP0/CPU0:router(config-l2vpn-bg-bd-pw)#
Adds an access pseudowire port to a bridge domain or a pseudowire to a bridge virtual forwarding interface (VFI).
• Use the A.B.C.D argument to specify the IP address of the cross-connect peer.
• Use the pw-id keyword to configure the pseudowire ID and ID value. The range is 1 to 4294967295.
Step 8
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.
Enabling Pseudowire Status TLV
When a pseudowire is setup, label distribution protocol (LDP) determines the method for signaling pseudowire
status. Cisco IOS-XR provides a configuration option that allows you to enable pseudowire status type length
value (TLV).
Note
Unless pseudowire status TLV is explicitly enabled under L2VPN configuration, the default signaling
method is Label Withdrawal. Pseudowire status TLV must be enabled on both local and remote PEs. If
only one provider edge router is configured with the pw-status tlv command, then label withdrawal method
is used.
