Classful(?) префиксы в http://noc.ix.net.ua/ua-list.txt
by Oleg Cherevko 11 Oct '08

11 Oct '08

Привет коллегам! Вот есть такой многим известный список префиксов UA-IX: http://noc.ix.net.ua/ua-list.txt В этом списке примерно треть префиксов не содержит явного указания длины netmask'и. Довольно очевидно, что неявно подразумевается, что они "/24". А вот почему так получается? Т.е. из-за чего одни префиксы имеют явные netmask'и, а другие нет? Кто-то где-то (Cisco?) работает с префиксами как с classful (а не classless)? (На всякий случай: я не предлагаю что-то менять, меня интересует только узнать причину появления таких префиксов в этом списке.) -- Olwi

Использование L2TP на 7600 ...
by Yury Yaroshevsky 11 Oct '08

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.

Уважаемые, а кто-то использует муксы от Люцент-Алькатель? Как правильно называется тип медного коннектора на E3/DS3 -картах их имени? Там не стандартный BNC, а что-то другое. -- Kind Regards, Alexander Shikoff AMS1-UANIC

FrameRelay over E1 на Juniper
by Alexander Shikoff 03 Oct '08

03 Oct '08

Добрый день! Стоит задача перенести FrameRelay, идущий поверх E1, с Cisco на Juniper. На Cisco поток приходил через E1 модем, в Juniper переключаю напрямую в E1 порт. На Cisco было: interface Serial0/0 bandwidth 2048 ip address x.x.x.x 255.255.255.252 ip access-group FW-IN in ip access-group FW-OUT out encapsulation frame-relay ip route-cache flow no fair-queue frame-relay interface-dlci 101 frame-relay lmi-type ansi На Juniper: > show configuration interfaces e1-1/0/0 encapsulation frame-relay; lmi { lmi-type ansi; } e1-options { framing unframed; } unit 0 { dlci 101; family inet { address x.x.x.x/30; } } Проблема в следющем: PVC поднимается, но трафик не едет: > show interfaces e1-1/0/0.0 Logical interface e1-1/0/0.0 (Index 68) (SNMP ifIndex 39) Flags: Point-To-Point SNMP-Traps Encapsulation: FR-NLPID Input packets : 0 Output packets: 289 [...] DLCI 101 Flags: Active, DCE-Configured Total down time: 00:31:59 sec, Last down: 00:19:58 ago Input packets : 0 ^^^^^^^^^^^^^^^^^ Output packets: 289 Удаленная сторона утверждает, что в мою сторону от них трафик уходит. Подскажите что не так? Спасибо. -- Kind Regards, Alexander Shikoff AMS1-UANIC

postfix redirect
by Gregory Edigarov 02 Oct '08

02 Oct '08

Всем привет, Вопрос на засыпку: предположим есть ящик user(a)domain1.com, на данный ящик приходит письмо от otheruser(a)otherdom.com и это письмо необходимо перенаправить на user2(a)dom2.com REDIRECT в access map не подходит в силу того, что otheruser(a)otherdom.com может слать и на другие ящики и вообще в другие домены, которые так-же обслуживает данный сервер. то-есть нужна возможность каким-то образом задать триплет: from to redirect_destination что-то такое в постфиксе есть? если нет - как извратиться без procmail и .forward? -- With best regards, Gregory Edigarov

будущее - за ATM, во как :-)
by Vladimir Litovka 02 Oct '08

02 Oct '08

Привет, коллеги ездили на какую-то "yet another" конференцию, и там выступал какой-то чел с кафедры связи института железнодорожников с большой речью, основной тезис которой - IP умирает, светлое будущее - за ATM, на пути к которому промежуточной стадией является Frame Relay. Пипец какой-то... откуда такие динозавры беруццо? -- /doka

Получение статистики с service instance на Ethernet порту ...
by Yury Yaroshevsky 01 Oct '08

Добрый вечер. Есть L2 канал, организованные на 7600 при помощи: interface GigabitEthernet3/0/5 [skip] service instance 1 ethernet encapsulation dot1q 1097 service-policy input pm-limit-in-1024K interface GigabitEthernet3/0/6 [skip] service instance 1 ethernet encapsulation dot1q 1099 service-policy input pm-limit-in-1024K connect TEST GigabitEthernet3/0/5 1 GigabitEthernet3/0/6 1 Возникла необходимость снимать статистику с service instance на GE порту. Как это сделать по SNMP? Что почитать?
