R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

584
prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63
characters.
tag tag-value: Specifies a tag value in the range of 1 to 4294967295.
Usage guidelines
The higher the convergence priority, the faster the convergence speed.
IPv6 IS-IS host routes have a medium convergence priority.
Examples
# Assign the high convergence priority to IS-IS routes permitted by IPv6 prefix list standtest.

set-overload
Use set-overload to set the overload bit.
Use undo set-overload to clear the overload bit.
Syntax
set-overload [ on-startup [ [ start-from-nbr system-id [ timeout1 [ nbr-timeout ] ] ] | timeout2 ] [ allow
{ external | interlevel } * ]
undo set-overload
Default
The overload bit is not set.

Parameters
on-startup: Sets the overload bit upon system startup.
start-from-nbr system-id [ timeout1 [ nbr-timeout ] ]: Starts the nbr-timeout timer when the router begins
to establish the neighbor relationship with the neighbor after system startup. If the neighbor relationship
is formed within the nbr-timeout interval, IS-IS keeps the overload bit set. If not, the bit is cleared. IS-IS
keeps the overload bit set within the timeout1 interval after the neighbor relationship is formed within the
nbr-timeout interval.
• system-id—Specifies the neighbor.
• timeout1—The value range for the timeout1 interval is 5 to 86400 seconds, and the default is 600
seconds.
• nbr-timeout—The timer has an interval from 5 to 86400 seconds. The default is 1200 seconds.
timeout2: Sets the overload bit within the timeout2 interval after system startup. The value range for the
interval is 5 to 86400 seconds, and the default is 600 seconds.
