Re: default-information originate route-map X

sorry forget to add even though it says in the doccd it is to be a standard
access-list, and the example shows using a wildcard mask in the standard
numbered list:

 Examples

The following example shows how to originate a default route (0.0.0.0/0)
over a certain interface when 172.17.0.0/16 is present. In this example a
route map condition is applied.

router rip

 version 2

 network 172.17.16.0

 default-information originate route-map condition

!

 route-map condition permit 10

 match ip address 10

 set interface s1/0

!

access-list 10 permit 172.17.16.0 0.0.0.255

"The route map referenced in the *default-information originate* command
cannot use an extended access list; it can use a standard access list."
