R211x-HP Flexfabric 11900 Layer 3 - IP Routing Command Reference

258
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 overload flag on the current router.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] set-overload
snmp context-name
Use snmp context-name to set the context name for the SNMP object for managing IS-IS.
Use undo snmp context-name to restore the default.

Usage guidelines
TRILL uses the IS-IS MIB to provide the TRILL object management function for NMS. Because the MIB
objects defined in the IS-IS MIB are single-instance management objects, NMS cannot manage IS-IS and
TRILL at the same time. According to the management for multiple OSPF instances defined in RFC 4750,
you can set a context name for the SNMP object for managing TRILL. In this way, the SNMP requests for
managing IS-IS and the SNMP requests for managing TRILL from NMS can be distinguished. Because the
context name is a concept specific to SNMPv3, the community names are mapped to context names for
distinguishing different protocols in SNMPv1/v2c.
