IV. Configuring the LSP retransmitting interval on an interface
On a point-to-point link, if there is no response for the sent LSP, the LSP is considered
lost or discarded and the sending router retransmits the LSP.
Follow these steps to configure LSP retransmitting interval:
Enter system view
Enter interface view
Configure the LSP
retransmitting interval on
a point-to-point link
V. Configuring the number of Hello packets expected from the remote router
before it is considered dead
In IS-IS, Hello packets are sent and received to maintain router neighbor relationships.
If a router does not receive any Hello packet from a neighboring router in a certain
period of time (Holddown time in IS-IS), the neighbor is considered dead.
In IS-IS, you can adjust the Holddown time by configuring the number of Hello packets
expected from a neighbor router before it is considered dead.
Follow these steps to configure the number of Hello packets expected from the
remote router before it is considered dead:
Enter system view
Enter interface view
Configure the number of
Hello packets expected
from the remote router
before it is considered
dead
