Symptoms: An L2TPv3 session is established when voluntary tunneling is configured and both peers
have corresponding configurations. However, after you configure a pseudowire on a virtual PPP
interface on one of the peers, the session on this peer is up but the line protocol is down, an a
“virtual-PPP1 is up, line protocol is down” error message is generated.

interface on one of the peers, the session on this peer is up but the line protocol is down, an a
“virtual-PPP1 is up, line protocol is down” error message is generated.
Conditions: This symptom is observed when the virtual PPP interface is first deleted via the no
interface virtual-ppp number command and then reconfigured via the interface virtual-ppp
number command before you configure a pseudowire on the virtual PPP interface.

number command before you configure a pseudowire on the virtual PPP interface.
Workaround: Before you configure a pseudowire on the virtual PPP interface, ensure that the virtual
PPP interface has never been unconfigured via the no interface virtual-ppp number configuration
command.

Symptoms: When Multilink PPP (MLP) is enabled for a PPP over Ethernet (PPPoE) session,
outbound packets are incorrectly sent without PPPoE headers. This situation causes packets to be
dropped.
outbound packets are incorrectly sent without PPPoE headers. This situation causes packets to be
dropped.
Conditions: This symptom is observed in Cisco IOS Release 12.4 on all software-forwarding routers
and affects only packets that are not multilink-encapsulated (when the bundle has only a single link).
and affects only packets that are not multilink-encapsulated (when the bundle has only a single link).
Workaround: Enter the ppp multilink fragment delay interface configuration command to force
multilink headers to be applied to all outbound packets.
multilink headers to be applied to all outbound packets.
Alternate Workaround: Disable MLP.
