Symptoms: A Data-link switching plus (DLSw+) circuit may not function when a TCP connection
gets stuck. After about 90 seconds, the TCP connection is closed by DLSw+, and a new TCP
connection is built for DLSw+. Once the new TCP connection is up, the DLSw+ circuit starts
functioning again.
gets stuck. After about 90 seconds, the TCP connection is closed by DLSw+, and a new TCP
connection is built for DLSw+. Once the new TCP connection is up, the DLSw+ circuit starts
functioning again.
Conditions: This symptom is observed on a Cisco router that is configured with both a DLSw+
interface and an ATM interface.
interface and an ATM interface.
Possible Workaround: If this is an option, remove the ATM interface from the router. When you
configure the DLSw+ interface and the ATM interface on different routers, the symptom does not
occur.

Workaround: Explicitly configure the [broadcast | no broadcast] option:
Router(config-if-atm-vc)# protocol ip 10.10.100.2 broadcast
Router(config-if-atm-vc)# protocol ip 10.10.100.2 ?

no Prevent Pseudo-broadcast on this connection

Symptoms: A PE that is part of a confederation and that has received a VPNv4 prefix from an
internal and an external confederation peer, may assign a local label to the prefix despite the fact
that the prefix is not local to this PE and that the PE is not changing the BGP next-hop.
internal and an external confederation peer, may assign a local label to the prefix despite the fact
that the prefix is not local to this PE and that the PE is not changing the BGP next-hop.
Conditions: The symptoms are observed when receiving the prefix via two paths from confederation
peers.
peers.
Workaround: There is no workaround.
Further Problem Description: Whether or not the PE will chose to allocate a local label depends on
the order that the multiple paths for this VPNv4 prefix are learned. The immediate impact is that the
local label allocated takes up memory in the router as the router will populate the LFIB with the
labels.
