Workaround: There is no workaround.
• CSCtw59780
Symptoms: BGP dynamic neighbor structures at the hub are not cleaned up after the spokes go
down. The output of the show ip bgp all sum command continues to display dynamic neighbors.
Conditions: This issue is observed when all the following conditions are met:
– The scale environment for dynamic neighbors contains several thousand peers.
– The peers are brought up and then removed before they can transition into the Established state.
Workaround: There is no workaround.
• CSCtw94068
Symptoms: The router displays traceback messages, after which interfaces stop passing traffic.
Conditions: The issue can occur when you reload the router
Workaround: There is no workaround.
• CSCtx02522
Symptoms: The router displays intermittent traceback errors.
Conditions: Occurs when you configure REP.
Workaround: There is no workaround.
• CSCtx37768
Symptoms: QoS classification does not match traffic against an egress policy map between MPLS
and IP access.
Conditions: Occurs when you apply a QoS policy on an EVC bridge domain interface.
Workaround: Use one of the following workarounds:
– Reload the router.
– Remove and re-apply an encapsulation configuration such a VLAN.
– Remove and re-attach the bridge domain under the EVC.
– Perform a shutdown/no shutdown on the BDI interface.
• CSCtx38156
Symptoms: The router crashes.
Conditions: Occurs when you remove the fast-reroute remote-lfa level-2 mpls-ldp command from
a configuration.
Workaround: This command is not currently supported; avoid including it in a configuration.
• CSCtx44508
Symptoms: There is a delay in route processor synchronization after an SSO.
Conditions: This issue is observed when iBGP NSR is enabled and under scale conditions.
Workaround: There is no workaround.
• CSCtx44688
Symptoms: Cannot configure policing and marking together in the same class of the egress
policy-map.
Conditions: Set and police statements together in the same class of a policy is rejected at the CLI.
