Chapter
Caveats in Cisco IOS XE 3.11S Releases
Symptom: MVPN traffic is incorrectly received by the receivers due to core replication not working.
Conditions: This issue occurs when large scale is present or when data MDT is used with scale for
MVPN.
Workaround: Use default MDT.
• CSCum26178
Symptom: Bert does not go in sync with hard loop; The reports display that the BERT is running
forever. The BERT cannot be stopped and a new BERT cannot be started.
Conditions: This issue occurs when hard loop is configured on OC-3 controller. The BERT is not in
sync & BERT is running forever & new BERT cannot be started.
Workaround: There is no workaround.
• CSCum65037
Symptom: The set ip next-hop peer-address command configured within a route-map does not
appear in the running-configuration, causing a loss in configuration across a reload.
Conditions: This issue occurs in Unified MPLS for Mobile transport model with IGP-LDP Access,
IGP routes (mainly CSG loopbacks) from Access ring would be redistributed into BGP in the
pre-aggregation device (Cisco ASR 903 router). When this happens, IGP next hops that are directly
connected to the pre-aggregation devices are treated as BGP next hops in the local BGP database of
the pre-aggregation device. Hence when the corresponding link goes down, there might be
unnecessary BGP next hop scan for AF IPv4 taking place.
Workaround: Reconfigure the set ip next-hop peer-address command within the route-map after
reboot of the device to get the intended functionality.
• CSCum69866
Symptom: ONS-SC-155-EL optic does not get recognized by the router when inserted in the OC-3
IM.
Conditions: This issue occurs on insertion of ONS-SC-155-EL optic in OC-3 IM in the router. An
error message gets displayed on the console that the transceiver is not supported The optic does not
get detected in show inventory command output.
Workaround: There is no workaround.
• CSCum81574
Symptom: Ingress PE node with pim-ssm gets crashed on sending multicast traffic.
Conditions: This issue occurs when the ode gets crashed when core MDT routes reach around 1K
with the video template.
Workaround: There is no workaround.
• CSCum92427
Symptom: Ping fails when ARP type goes to UNKNOWN state.
Conditions: This issue occurs when the Cisco ASR 903 router resides between the DHCP sever and
a Cisco ASR 901 router, which acts as a helper.
Workaround: Perform a shutdown followed by a no shutdown on the interface. Execute clear
arp-cache to clear the cache.
