Добрый вечер. Использует ли у себя кто-нибудь на 7600 L2TPv3 ? Посоветуйте что еще сделать мне в ситуации описанной ниже для того что бы выяснить в чем может быть проблема. Есть необходимость в организации L2TPv3 туннелей между 7600 и 18xx, 28xx. Настраиваю туннели следующим образом: на 7600: interface Loopback77 ip address a.a.a.a 255.255.255.255 pseudowire-class PW-L2TP-TEST encapsulation l2tpv3 ip local interface Loopback77 interface GigabitEthernet3/0/5.36 encapsulation dot1Q 933 no ip redirects no ip proxy-arp xconnect b.b.b.b 1333 pw-class PW-L2TP-TEST На 2811: interface Loopback77 ip address b.b.b.b 255.255.255.255 pseudowire-class PW-L2TP-TEST encapsulation l2tpv3 ip local interface Loopback77 interface Fa0/1.16 encapsulation dot1Q 1333 no ip redirects no ip proxy-arp xconnect a.a.a.a 1333 pw-class PW-L2TP-TEST Туннели не поднимаются: Это состояние на 7600 : a.a.a.a#sh l2tun tunnel all L2TP Tunnel Information Total tunnels 1 sessions 1 Tunnel id 675875571 is down, remote id is 48161, 1 active sessions ^^^^^^^^^ ^^^^^ Remotely initiated tunnel Tunnel state is Wt-SCCCN, time since change 00:01:46 ^^^^^^^ Tunnel transport is IP (L2TP) (115) Remote tunnel name is b.b.b.b Internet Address b.b.b.b, port 0 Local tunnel name is a.a.a.a Internet Address a.a.a.a, port 0 L2TP class for tunnel is l2tp_default_class Counters, taking last clear into account: 0 packets sent, 0 received 0 bytes sent, 0 received Last clearing of counters never Counters, ignoring last clear: 0 packets sent, 0 received 0 bytes sent, 0 received Control Ns 1, Nr 1 Local RWS 1024 (default), Remote RWS 1024 (max) Control channel Congestion Control is enabled Congestion Window size, Cwnd 1 Slow Start threshold, Ssthresh 2 Mode of operation is Slow Start Retransmission time 8, max 8 seconds Unsent queuesize 0, max 0 Resend queuesize 1, max 1 Total resends 15, ZLB ACKs sent 0 Total peer authentication failures 0 Current no session pak queue check 0 of 5 Retransmit time distribution: 0 0 1 0 1 0 0 0 13 Control message authentication is disabled Это состояние на 2811 : b.b.b.b#show l2tun tunnel all L2TP Tunnel Information Total tunnels 1 sessions 1 Tunnel id 48161 is up, remote id is 2803, 1 active sessions ^^^^^ ^^^^ Locally initiated tunnel Tunnel state is established, time since change 00:01:45 ^^^^^^^^^^^ Tunnel transport is IP (L2TP) (115) Remote tunnel name is a.a.a.a Internet Address a.a.a.a., port 0 Local tunnel name is b.b.b.b Internet Address b.b.b.b, port 0 L2TP class for tunnel is l2tp_default_class Counters, taking last clear into account: 0 packets sent, 0 received 0 bytes sent, 0 received Last clearing of counters never Counters, ignoring last clear: 0 packets sent, 0 received 0 bytes sent, 0 received Control Ns 3, Nr 1 Local RWS 1024 (default), Remote RWS 1024 (max) Control channel Congestion Control is enabled Congestion Window size, Cwnd 1 Slow Start threshold, Ssthresh 2 Mode of operation is Slow Start Retransmission time 8, max 8 seconds Unsent queuesize 0, max 0 Resend queuesize 2, max 2 Total resends 30, ZLB ACKs sent 14 Total peer authentication failures 0 Current no session pak queue check 0 of 5 Retransmit time distribution: 0 0 1 0 1 0 0 0 13 Control message authentication is disabled Смущает следующее: 1) Несовпадение Tunnel id (см. выше) 2) 2811 считает туннель поднятым, в отличии 7600.
