Configuring the source IP address of L2TP tunnel packets
As a best practice to ensure high availability, use the IP address of a loopback interface as the source IP address of L2TP tunnel packets on the LAC. If equal cost routing paths exist between the LAC and LNS, you must use the IP address of a loopback interface as the source IP address of L2TP tunnel packets. To do so, use the source-ip command or use the RADIUS server to assign a loopback interface address.
To configure the source IP address of L2TP tunnel packets:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter L2TP group view in LAC mode. | l2tp-group group-number [ mode lac ] | N/A |
3. Configure the source IP address of L2TP tunnel packets. | source-ip ip-address | By default, the source IP address of L2TP tunnel packets is the IP address of the egress interface. |
