router(config-router)#neighbor 10.1.2.75 default-originate
% Invalid command for a peer-group member
router(config-router)#

According to Cisco:
All members of a peer group must share identical outbound announcement policies (such as distribute-list, filter-list, and route-map), except for default-originate, which is handled on a per-peer basis even for peer group members.

I've also tried to apply to the peer group. The command is accepted, but no default origination of 0/0 is advertised to the peer(s).
Thanks in advanced for any help,

After you applied default-originate to peer-group, have you done soft-clear of your bgp session?

It usually takes a little while for changes in config to propagate, unless you force an update using soft clear...

As I recall, making changes to a peer-group outbound
policy will require all of the peer-group members to
reset (or at least the peer-group leader). Until that
reset happens, a soft clear to a follower session will
only re-send the output of the previously calcluated
policy.

I seem to remember this as an undocumented feature...
