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:

Смущает следующее:
1) Несовпадение Tunnel id (см. выше)
2) 2811 считает туннель поднятым, в отличии 7600.
После включения debug l2tp event вижу следующее:
