  1. т.е. этот asr имеет функционал nat, но применить его нет возможности?
  2. да, сабы пробовали первым делом, но в ASR есть ограничения ASR(config)#interface TenGigabitEthernet0/1.4 ASR(config-subif)#ip address 10.7.2.1 255.255.254.0 IP address config under this interface is not supported on ASR901 ASR(config-subif)# Этот затык трафика похож на какое-то специальное ограничение, типа лицензионное или что-то подобное. Лицензия на nat, такое вообще бывает? наши вот ASR#sh lic Index 1 Feature: AdvancedMetroIPAccess Period left: Life time License Type: Permanent License State: Active, In Use License Count: Non-Counted License Priority: Medium Index 2 Feature: IPBase Period left: Life time License Type: Permanent License State: Active, Not in Use License Count: Non-Counted License Priority: Medium Index 3 Feature: Gige4portflexi Index 4 Feature: 10gigUpgrade Index 5 Feature: 1588BC
  3. на нем написано cisco ASR901 series router nat-трансляции же идут, но только с внутреннего vlan. такое ощущение, что bridge как-то должны быть настроены знаете что заметили), когда добавлям или убираем дефолтный маршрут ASR(config)#ip route 0.0.0.0 0.0.0.0 Vlan2 ASR(config)#no ip route 0.0.0.0 0.0.0.0 Vlan2 ASR(config)#ip route 0.0.0.0 0.0.0.0 Vlan2 один icmp-пакет с ноутбука успершо проходит в сеть 192.168.1.0, а потом опять все глохнет.
  4.

  5. Друзья подскажите пожалуйста, вопрос вроде простой, но непонятно как сделать. Пытаемся сделать обычный нат. 192.168.1.1 <==> ASR 901(10.7.2.1) <==> C2960(10.7.2.4) <==> Ноут(10.7.2.11) - Есть ASR 901 у него GigabitEthernet0/4 смотрит во внешнюю сеть и TenGigabitEthernet0/1 к C2960. - Подняли нат но трафик от абонента на коммутаторе и с самого 2960 в него не попадает, хотя все vlans поднялись и все друг-друга видят. ASR#p 10.7.2.4 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.7.2.4, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms ASR#p 10.7.2.11 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.7.2.11, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms - С2960 тоже видит всех кроме внешней сети С2960#ping 10.7.2.1 source vlan 4 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.7.2.1, timeout is 2 seconds: Packet sent with a source address of 10.7.2.4 !!!!!

Success rate is 0 percent (0/5) - Сам роутер со своего интерфейса внешнюю сеть видит, а трафик который приходит с коммутатора в нат не попадает. ASR#ping 192.168.1.1 source vlan4 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds: Packet sent with a source address of 10.7.2.1 !!!!!
