Enabling An Interface To Send Small Hello Packets; Configuring Lsp Parameters - HP MSR Series Configuration Manual

If a PPP interface's peer IP address is on a different network segment, disable the hello source address
check for the PPP interface to establish the neighbor relationship with the peer.
To enable neighbor relationships over different network segments:
Step
1. Enter system view.
2. Enter interface view.
3. Disable hello source
address check for the PPP
interface.

Enabling an interface to send small hello packets

IS-IS messages cannot be fragmented at the IP layer because they are directly encapsulated into frames.
Any two IS-IS neighboring routers must negotiate a common MTU. To avoid sending big hellos for saving
bandwidth, enable the interface to send small hello packets without CLVs.
To enable an interface to send small hello packets:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the interface to send
small hello packets without
CLVs.

Configuring LSP parameters

Configuring LSP timers
1. Specify the maximum age of LSPs
Each LSP has an age that decreases in the LSDB. Any LSP with an age of 0 is deleted from the LSDB.
You can adjust the age value based on the scale of a network.
To specify the maximum age of LSPs:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the maximum LSP
age.
2. Specify the LSP refresh interval and generation interval
