OL-10394-05 Rev. R0
router#show ip cef vrf <vrf name> x.x.x.x int [snip] MPLS short path extensions: MOI
flags = 0x16 <-------MOI flags 0x10 is incorrectly set for iBGP when it becomes best
path, correct flag should be 0x4, 0x5, 0x6 ... correct now.
2. The No_Global bit (0x10) for MOI flag for iBGP path was incorrectly unset when eBGP becomes
best path.
router#show ip cef vrf <vrf name> x.x.x.x int [snip] MPLS short path extensions: MOI
flags = 0x5 <-------MOI flags 0x10 is incorrectly clear for i/jointfilesconvert/422273/bgp path when eBGP
becomes best path, correct flag should be 0x14, 0x15, 0x16... correct now.
Conditions: This symptom sometimes happens after BGP path update.
Workaround: Issue the clear ip route vrf vrf name x.x.x.x/y command.
• CSCsl99629
Symptoms: PIM hello packets are dropped and PIM neighbor is lost.
Conditions: The problem happens when IGMP rate limiter is configured and global PIM snooping
is turned on, such as in the following configuration:
mls rate-limit multicast ipv4 igmp 500 100 ip pim snooping
Workaround: There is no workaround.
• CSCsm00570
Symptoms: FlexWAN card crashes after a service policy is attached to sub-interface in which
mulitlink is configured, followed by shut/no shut.
Conditions: This problem requires both a QoS configuration change and an interface flap to happen
at the same time. It is not likely to happen in production environments.
Workaround: There is no workaround.
• CSCsm00811
Symptoms: In the following configuration
TGN--------UUT1(atm4/0.1)---------(atm3/0.1)UUT2----------PKTS
UUT2 hangs if IPv6 traffic is sent from TGN to PKTS through ATM subinterface.
Conditions: Occurs when IPv6 CEF is enabled.
Workaround: There is no workaround.

Conditions: This symptom is observed when the router has a configuration greater than 0.5
megabytes.
Workaround: There is no workaround.
