Symptoms: When asynchronous serial interfaces are used as member links in multilink PPP bundles,
the router may crash due to memory corruption.
the router may crash due to memory corruption.
Conditions: This problem can occur under conditions where multilink fragmentation is done, and
where the bundle includes at least one member link that is an asynchronous interface.
where the bundle includes at least one member link that is an asynchronous interface.
Workaround: Disable fragmentation on the bundle interface for any bundle that may include
asynchronous links as members. Alternatively, if the use of multilink is not a requirement, disable
multilink on the asynchronous interfaces.

Symptoms: VPDN loadbalancing incorrectly biases to one LNS (IP address) instead of sharing the
session load between the different LNSs after LNS return from the busy list.

Conditions: This occurs when multiple LNSs are configured for one vpdn-group and are
unreachable. They are moved to the busy list. Once the LNSs become reachable again, this problem
occurs.

Symptoms: When a Telnet session is made to a router after a VTY session pauses indefinitely, the
user in the Telnet session may not be able to enter the configuration mode. When these symptoms
occur, interfaces may enter the wedged state with Simple Network Management Protocol (SNMP)
traffic.
