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

585
allow: Allows advertising address prefixes. By default, no address prefixes are allowed to be advertised
when the overload bit is set.
external: Allows advertising IP address prefixes redistributed from other routing protocols with the allow
keyword specified.
interlevel: Allows advertising IP address prefixes learned from different IS-IS levels with the allow
keyword specified.
Usage guidelines
If the on-startup keyword is not specified, the command sets the overload bit immediately until the undo
set-overload command is executed.
If the on-startup keyword is specified, IS-IS sets the overload bit upon system startup and keeps it set
within the timeout2 interval.
Examples
# Set the overload bit on the current router.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] address-family ipv6
[Sysname-isis-1-ipv6] set-overload
