This might be posted before:
Can someone can summarize how many ways to summarize routes? such as:
1. OSPF use area rnage;
2. OSPF use summary address;
3.
4.
....
How many ways to generate default routes:, such as
1. OSPF use default-information originate
2. static ip route 0.0.0.0 0.0.0.0 interface name/next hop IP address
3. EIGRP redistribute static or other routing protocols
4. IP default-network
....
Thanks,
Song
