HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

407
&<1-n>: Indicates that the argument before it can be entered up to n times. The value of n depends on
the device model.
Usage guidelines
You can specify multiple default output interfaces for backup or load sharing by executing this command
once or multiple times.
You can specify up to m default output interfaces for a node. The value of m depends on the device
model.
The default output interface must be P2P type. Using a non-P2P default output interface (broadcast and
NBMA interfaces such as Ethernet and virtual-template interfaces) can result in forwarding failures when
the interface has multiple next hops. In non-broadcast multi-access (NBMA) networks, packets are sent in
unicast.
With a default output interface specified, the undo apply default-output-interface command removes the
default output interface.
Without any default output interface specified, the undo apply default-output-interface command
removes all default output interfaces.
Examples
# Specify Serial 2/0 as the default output interface for IP packets.
<Sysname> system-view
[Sysname] policy-based-route aa permit node 11
[Sysname-pbr-aa-11] apply default-output-interface serial 2/0
Related commands
apply loadshare default-output-interface
apply ip-df
Use apply ip-df to set the Don't Fragment (DF) bit in the IP header of matching packets.
Use undo apply ip-df to restore the default.
Syntax
apply ip-df df-value
undo apply ip-df
Default
The DF bit is not set.
Views
Policy node view
Predefined user roles
network-admin
Parameters
df-value: Sets the DF bit in the IP header of matching packets. The value can be 0 or 1.
Usage guidelines
Setting the DF bit to 0 allows packet fragmentation.
