disp l2tp sessions可以看到会话established后立刻就消失。
设备回显信息显示VA不停的up/down

radius服务器收不到任何认证消息。
路由器为l2tp接入,由另一台路由器做ipsec加密,用户认证方式为radius。
本次将原思科路由器更换为h3c路由器,思科路由器业务正常,正常情况下有十个l2tp隧道,300多个l2tp会话。根据思科路由器的配置进行的翻译。
运营商一根专线接入。

最佳答案
估计配置有啥问题,配置贴一下,然后在设备上开下边几个deb看看:
deb l2tp all
deb ppp all
deb radius packet
t d
t m
看看报文交互过程有没有什么异常

debug信息没有抓全,窗口时间太短,他上线终端太多。 只有少部分l2tp的。参考意义不大。 只有个Dropped an L2TP data packet 的报错。 *Nov 22 01:55:17:091 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KDATA-PKT: -Slot=3; Successfully parsed the L2TP header (L2TP header length=6):TunnelID:50583,SessionID:54625,Type:0,Length:0,Sequence:0,Offset: 0,Priority:0 *Nov 22 01:55:17:091 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KERROR: -Slot=3; Dropped an L2TP data packet. *Nov 22 01:55:17:097 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KDATA-PKT: -Slot=3; Received an L2TP data packet: Source IP: 192.168.2.102 Destination IP: 10.2.39.50 Source port: 1701 Destination port: 1701 *Nov 22 01:55:17:097 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KDATA-PKT: -Slot=3; Successfully parsed the L2TP header (L2TP header length=6):TunnelID:6570,SessionID:54487,Type:0,Length:0,Sequence:0,Offset: 0,Priority:0 *Nov 22 01:55:17:097 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KERROR: -Slot=3; Dropped an L2TP data packet. *Nov 22 01:55:17:136 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KDATA-PKT: -Slot=3; Received an L2TP data packet: Source IP: 192.168.2.103 Destination IP: 10.2.39.50 Source port: 1701 Destination port: 1701 *Nov 22 01:55:17:136 2018 DC_UNI_3G_R5660_01 L2TPV2/7/KDATA-PKT: -Slot=3; Successfully parsed the L2TP header (L2TP header length=6):TunnelID:29061,SessionID:54627,Type:0,Length:0,Sequence:0,Offset: 0,Priority:0
