Use the asbr-summary command to configure summarization of imported routes 
by OSPF.

Use the undo asbr-summary command to cancel the summarization.

By default, summarization of imported routes is disabled.

After the summarization of imported routes is configured, if the local router is an 
autonomous system border router (ASBR), this command summarizes the 
imported Type-5 LSAs in the summary address range. When NSSA is configured, 
this command will also summarize the imported Type-7 LSAs in the summary 
address range.

If the local router acts as both an ABR and a router in the NSSA, this command 
summarizes Type-5 LSAs transformed from Type-7 LSAs. If the router is not the 
router in the NSSA, the summarization is disabled.

simple: Uses simple text authentication mode.

md5: Uses MD5 cipher text authentication mode.

Use the authentication-mode command to configure one area of OSPF to 
support the authentication attribute.

Use the undo authentication-mode command to cancel the authentication 
attribute of this area.

By default, an area does not support authentication attribute.

All the routers in one area must use the same authentication mode (no 
authentication, simple text authentication or MD5 cipher text authentication). If 
the mode of supporting authentication is configured, all routers on the same 
segment must use the same authentication key. To configure a simple text 
authentication key, use the ospf authentication-mode simple command. Use
