Setting The Tsa Id Of The Lts; Displaying And Maintaining L2Tp - HP MSR Router Series Wan Access Configuration Manual

Step
3. Assign the tunnel peer to a
VPN.

Setting the TSA ID of the LTS

To detect loops, the LTS compares the configured TSA ID with each TSA ID AVP in a received ICRQ
packet.
If a match is found, a loop exists. The LTS immediately tears down the session.
•
• If no match is found, the LTS performs the following operations:
Encapsulates the configured TSA ID into a new TSA ID AVP.
Appends it to the packet.
Sends the packet to the next hop LTS.
To avoid loop detection errors, make sure the TSA ID of each LTS is unique.
To set the TSA ID of the LTS:
Step
1. Enter system view.
2. Set the TSA ID of the LTS and
enable L2TP loop detection on
the LTS.

Remarks
By default, a tunnel peer belongs
to the public network.
The tunnel peer and the physical
port connecting to the tunnel peer
should belong to the same VPN.
The VPN to which this physical
port belongs is configured by
using the ip binding vpn-instance
command.
Remarks
N/A
By default, the TSA ID of the LTS is
not configured, and L2TP loop
detection is disabled on the LTS.
