Resolved Caveats—Cisco IOS Release 12.4(5a)
Conditions: This symptom is observed on a Cisco router when the members of a BGP update group
go out of synchronization with each other in such a way that they have different table versions,
preventing the BGP Scanner from freeing networks that do not have a path.
go out of synchronization with each other in such a way that they have different table versions,
preventing the BGP Scanner from freeing networks that do not have a path.
To check if the members of the BGP update group are in synchronization with each other, enter the
show ip bgp update-group summary command and look at the table version for each member. If
they have the same table version, they are in synchronization with each other; if they do not, they
are out of synchronization with each other.

are out of synchronization with each other.
Workaround: To enable the members of the BGP update group to synchronize with each other, enter
the clear ip bgp * soft out command. Doing so does not bounce the sessions but forces BGP to
re-advertise all prefixes to each member.

This DDTS removes the code that automatically configures this line.
If customers are using CCM MGCP fax relay between gateways that are running older Cisco IOS
versions, and the Cisco IOS Release 12.4T with this change, the fax connections originating from
the gateways that are running previous Cisco IOS versions and terminating on the Cisco IOS
Release 12.4T gateway will fail unless "mgcp fax t38 inhibit" is configured on the Cisco IOS
Release 12.4T gateway.

If all gateways in the customer network are running the new Cisco IOS Release 12.4T with this fix,
then they may configure which ever mode as desired.
