Symptoms: If an access control list (ACL) is used for a destination only prefix, a fatal error is
declared and shuts down optimized edge routing (OER). For destination only traffic classes,
prefix-list should be used, not ACL or access control entry (ACE).

Conditions: This behavior is observed on Cisco IOS Release 12.4(11)T and later releases at this
time.
time.
Workaround: Use prefix list instead of ACL/ACE for destination only traffic classes. For example:
- use prefix list for a traffic class 100.1.1.0/24 - use ACE for traffic class 100.1.1.0/24 DSCP af11
- use prefix list for a traffic class 100.1.1.0/24 - use ACE for traffic class 100.1.1.0/24 DSCP af11

Symptoms: When a bidir PIM, with no directly connected receivers, router has to change its RPF
interface to the RP, multicast traffic could be lost for up to 60 seconds.
interface to the RP, multicast traffic could be lost for up to 60 seconds.
Conditions: This symptom occurs if the connection to the first RP is lost and the middle router
changes its RPF for its bidir upstream interface. The middle router then restarts the election process
on all DF interfaces, and purges the interface point in the leaf router out its OI @L. That interface
will only get repopulated upon a periodic state refresh from the leaf router because the leaf router
does not have an RPF change and therefore has no reason to send a triggered Join.

Symptoms: A spurious access error occurs in tfib_post_table_change_sanity_check () function.
Conditions: This symptom occurs if route is deleted. ROUTE_DOWN event is triggered in
tfib_post_table_change() function which in turn calls tfib_post_table_sanity_check(). In that
function, spurious access is reported, as the only path of route is down.

Symptoms: IMA group interface does not come up after the reload.
Conditions: This symptom is observed on a Cisco 2811 router with ATM interface that is using
VWIC2-2MFT-T1/E1 connected to MGX AUSUM card.

Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the IMA interface.
