ip vrf receive sak-voip
ip address 10.100.220.26 255.255.255.254
no ip redirects
no ip proxy-arp
ip mtu 1500
ip policy route-map sak-vrfs-in2

!
Workaround 3: Create a dummy interface and apply this route-map first on the dummy interface (but
do not delete the sub-interface).
CSCtf51541
Symptoms: After a parity error is detected in the system controller and a soft-reset is performed,
inband traffic may be interrupted in one direction.
The following log message indicates that the error occurred and a soft-reset was performed:
%SYSTEM_CONTROLLER-SP-3-ERROR: Error condition detected: TM_DATA_PARITY_ERROR
Conditions: No particular hardware or software configuration has been identified to contribute to
this. The issue is due to transient hardware errors.
Workaround: Configure EEM policy to look for the error and trigger an immediate switchover.
CSCtf53672
Symptoms: A router crashes when any CWAN module is not responding to the RP keepalives.
Conditions: The symptom is observed with a Supervisor 32.
Workaround: There is no workaround.
CSCtf54561
Symptoms: A MPLS TE FRR enabled router can encounter a crash if the show ip cef vrf vrf-name
command is issued.
Conditions: This symptom occurs when the VRF contains many entries (17k) in which the outgoing
interface changes due to a topology change.
Workaround: Command should not be issued when many topology changes occur on interface flaps.
CSCtf64235
Symptoms: Distributed LFI over ATM (dLFIoATM) session does not ping after switchover when
router is configured in SSO mode.
Conditions: The symptom is observed when the global redundancy mode is SSO.
Workaround: Perform a shut and no shut on the ATM physical interface.
CSCtf74073
Symptoms: Enhanced FlexWAN resets upon copying a scaled configuration.
Conditions: The symptom is observed upon directly copying a scaled configuration into the running
configuration.
Workaround: Copy configuration into start up from the disk or any other source file.
CSCtf75053
Symptoms: DHCP Relay will send a malformed DHCP-NAK packet. The malformed packet will be
missing the END option (255) and the packet’s length will be truncated to 300. In effect, all the
options after 300 bytes, if any, will be missing.
Conditions: When a Cisco 10000 series router is configured as a relay and a DHCP request is sent
from the CPE, the router will send a DHCP-NAK when client moves into a new subnet.
