Enabling BSoD
The following is a listing of basic tasks for enabling the BSoD feature. Steps 1 and 2 are beyond the scope of this document.
1.
Determine which Business customer will be using the L2VPN service. Assign the appropriate VPNID and Q-tags to the
customer by creating a unique CM config file for each customer’s modem.
2.
Update the provisioning server so that the modems get the proper configuration files.
3.
Configure the CMTS L2VPN feature.
A)
Enable L2VPN on the CMTS:
configure l2vpn forwarding enable
B)
Enable L2VPN forwarding for each cable-mac which will be servicing a L2VPN modem:
configure l2vpn cable-mac 1
configure l2vpn cable-mac 2
configure l2vpn cable-mac 3
C)
Configure the primary and secondary Network interfaces:
configure l2vpn network-interface gigabitEthernet 17/9 primary
configure l2vpn network-interface gigabitEthernet 18/9 secondary
D)
(Optional) If you want to support non-compliant L2VPN modems, you must set the L2VPN CM capability to optional:
configure l2vpn cm capability optional
E)
Configure the assigned Q-tag ranges to be used for VPN service:
(Note: Q-tags may also be used for layer 3 sub-interfaces and need to be specifically assigned to be used for L2VPN.)
configure l2vpn vlanid-range 201-240 single-qtag
configure l2vpn vlanid-range 300 dual-qtag
