IP Gateway
OSPF
- When OSPF is running over an on-demand PPP link and the link goes down, IP
notifies OSPF that the link is down and OSPF stops sending Hello packets over the
link. In a network in which routes over the PPP link are all dynamically learnt
through OSPF, the PPP link will not come back up because without OSPF there
are no routes to direct traffic at that link.
This enhancement enables you to stop IP from notifying OSPF that the PPP link is
down. OSPF keeps sending Hello messages, which bring the link back up again.
To enable this feature, set the new optional notifyospfdown parameter to no
in one of the commands:
ADD IP INTerface=int NOTIfyospfdown={NO|YES} [other parameters]
SET IP INTerface=int NOTIfyospfdown={NO|YES} [other parameters]
The default value for this parameter is yes, which means that IP notifies OSPF
when the interface goes down and OSPF sets the interface state to Down. OSPF
does not send Hello messages to the interface, and OSPF is inactive on the
interface until it receives an Up notification. This is the behaviour prior to this
enhancement. Also note the following points:
■ the parameter applies to the entire IP interface, not an individual logical
interface. Setting it on one logical interface sets it on all other logical
interfaces associated with the same IP interface.
■ the parameter only applies to on-demand PPP links. IP always sends
notifications for other interfaces, even if this parameter is set to no.
To see the parameter setting, use the existing command show ip interface.

Switch, EPSR - EPSR uses a classifier-based hardware filter to select packets in the control VLAN.
The hardware filter now only uses 2 of the available 16 bytes to match packets.
This increases the number of other classifier-based features you can use when
running EPSR.
