Configuring Ldp Md5 Authentication; Configuring An Lsp Generation Policy - HP 10500 Series Configuration Manual

The LDP backoff mechanism can mitigate this problem by using an initial delay timer and a maximum
delay timer. After LDP fails to establish a session with a peer LSR for the first time, LDP does not start an
attempt until the initial delay timer expires. If the session setup fails again, LDP waits for two times the
initial delay before the next attempt, and so forth until the maximum delay time is reached. After that, the
maximum delay time will always take effect.
To configure LDP backoff:
Step
1. Enter system view.
2. Enter LDP view or enter
LDP-VPN instance view.
3. Configure the initial delay
time and maximum delay
time.

Configuring LDP MD5 authentication

To improve security for LDP sessions, you can configure MD5 authentication for the underlying TCP
connections to check the integrity of LDP messages.
For two LDP peers to establish an LDP session successfully, make sure the LDP MD5 authentication
configurations on the LDP peers are consistent.
To configure LDP MD5 authentication:
Step
1. Enter system view.
2. Enter LDP view or enter
LDP-VPN instance view.
3. Enable LDP MD5
authentication.

Configuring an LSP generation policy

An LSP generation policy controls the number of LSPs generated by LDP in one of the following ways:
Use all routes to establish LSPs.
•
• Use the routes permitted by an IP prefix list to establish LSPs. For information about IP prefix list
configuration, see Layer 3—IP Routing Configuration Guide.
