Default route
You can generate an external default route and distribute the default information to the OSPFv2 routing domain.
• To generate the default route, use the default-information originate [always] command in ROUTER-OSPF mode.
Congure default route
OS10(config)# router ospf 10
OS10(config-router-ospf-10)# default-information originate always

Summary address
You can congure a summary address for an ASBR to advertise one external route as an aggregate, for all redistributed routes that are
covered by specied address range.
• Congure the summary address in ROUTER-OSPF mode.

Graceful restart
When a networking device restarts, the adjacent neighbors and peers detect the condition. During a graceful restart, the restarting device
and the neighbors continue to forward the packets without interrupting the network performance. The neighbors that help in the restart
process are called as helper routers.
