Да я поднял L3 на порту источника, теперь конфиг имеет вид: ip multicast-routing dist interface vlan 1 /влан получателя ip addr 176.56.22.22 ip pim passive interface G1/0/10 / источник no switchport ip addr 172.16.100.1 ip pim dense-mode Поставил режим dense так как рекомендуют именно его если как у меня всего один мультикаст роутер, однако все равно не работает...

Может вирус какой то в сети делающий запросы всех подряд групп? Хотя зачем? Хочется добавить, что если я с тестовой машины запрашиваю данную группу, то в выводе команды sh ip igmp gr показывает меня в качестве репортера, но через некоторое время снова тот адрес...

Да читал я тот блог, более того с автором переписывался, пока ничем не помогло, про PIM написал же, что не посредственно для интерфейсов команда не доступна, для вланов ТОЛЬКО passive mode и с прописыванием оно ничего не менятся. Едиснтвенное где можно писать sparse, dence, sparse-dence это loopback он у меня в качестве RP сейчас...

Неужели никто не может помочь? =)

Доброго времени суток всем, нуждаюсь в помощи по настройке вещания на оборудовании из сабжа... Собственно в качестве источника стоит EMR, из него в Catalyst 3750x, из него в DLink 1210-28 и далее в сеть... На данном этапе настроено вещание лишь одного ТВ канала, для пробы, сеть и порт источника в разных вланах, далее прописано: ip igmp snooping vlan 1 mrouter interface Gi1/0/10 ip igmp snooping vlan 10 ip igmp profile 10 permit range 224.10.10.10 224.10.10.10 и на интерфейсе Gi1/0/5 - он смотрит на DLink ! interface GigabitEthernet1/0/10 switchport access vlan 10 switchport mode access snmp trap mac-notification change added snmp trap mac-notification change removed spanning-tree port-priority 0 ip igmp filter 10 vlan 1 это сеть, vlan 10 и Gi1/0/10 это соответственно источник, 224.10.10.10 группа которую для теста вещаю. Pim не включал, так как пока не понимаю как он работает на данном девайсе, тут доступен лишь режим ip pim passive... Собственно на тестовой машинке картинка есть, нареканий пока что нет, есть несколько вопросов: 1. В целом интересует почему резко возрастает нагрузка на цпу как только включаю snooping на первом влане, при чем нагрузка скачет наверное каждые 2 секунды, то резко падает, то резко подлетает вверх c3750x#sh proc cpu s CPU utilization for five seconds: 45%/1%; one minute: 58%; five minutes: 62% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 301 8725443 3063054 2848 27.20% 40.18% 43.54% 0 IGMPSN 172 17440487 27600636 631 4.48% 3.87% 3.74% 0 Hulc LED Process 125 32473926 54238746 598 3.68% 2.78% 2.64% 0 hpm main process 219 7093743 39492161 179 1.75% 1.69% 1.70% 0 IP Input 85 1383455 3709795 372 0.47% 0.15% 0.14% 0 RedEarth I2C dri 86 3217423 3195688 1006 0.31% 0.28% 0.32% 0 RedEarth Tx Mana 129 1920164 1113314 1724 0.31% 0.25% 0.26% 0 hpm counter proc 325 486176 34644523 14 0.15% 0.04% 0.00% 0 MMON MENG 352 22446 206027 108 0.15% 0.13% 0.08% 0 PIM Process 178 96535 112422 858 0.15% 0.91% 1.06% 0 IGMP Input Часто нагрузка составляет 80%. Это нормальное поведение для igmp snooping ? 2. Второе что интересует это откуда берутся эти записи: c3750x#sh ip igmp snooping group Vlan Group Type Version Port List ----------------------------------------------------------------------- 1 224.0.1.24 igmp v2 Gi1/0/7 1 224.0.1.60 igmp v2 Gi1/0/7 1 224.0.2.60 igmp v2 Gi1/0/7 1 224.10.10.10 igmp v2 Gi1/0/5 1 226.100.10.15 igmp v2 Gi1/0/7 1 226.100.10.29 igmp v2 Gi1/0/7 1 226.100.10.31 igmp v2 Gi1/0/7 1 226.100.10.49 igmp v2 Gi1/0/7 1 226.100.10.56 igmp v2 Gi1/0/7 1 226.100.10.69 igmp v2 Gi1/0/7 1 233.89.188.1 igmp v2 Gi1/0/6, Gi1/0/8, Gi1/0/9 1 239.0.0.250 igmp v2 Gi1/0/8 1 239.192.152.143 igmp v2 Gi1/0/6, Gi1/0/7, Gi1/0/8 1 239.254.1.2 igmp v2 Gi1/0/9 1 239.255.67.250 igmp v2 Gi1/0/6, Gi1/0/7 1 239.255.255.100 igmp v1,v2 Gi1/0/6, Gi1/0/7, Gi1/0/8, Gi1/0/9 1 239.255.255.177 igmp v2 Gi1/0/7 1 239.255.255.246 igmp v2 Gi1/0/7 1 239.255.255.250 igmp v2 Gi1/0/6, Gi1/0/7, Gi1/0/8, Gi1/0/9 1 239.255.255.253 igmp v2 Gi1/0/7 1 239.255.255.254 igmp v2 Gi1/0/7 c3750x#sh ip igmp mem Flags: A - aggregate, T - tracked L - Local, S - static, V - virtual, R - Reported through v3 I - v3lite, U - Urd, M - SSM (S,G) channel 1,2,3 - The version of IGMP, the group is in Channel/Group-Flags: / - Filtering entry (Exclude mode (S,G), Include mode (G)) Reporter: <mac-or-ip-address> - last reporter if group is not explicitly tracked <n>/<m> - <n> reporter in include mode, <m> reporter in exclude Channel/Group Reporter Uptime Exp.

Как управлять потоком в таких условиях и почему коммутатор не воспринимает данный поток как мультикастовый? c3750x#sh ip multicast int vlan 10 Vlan10 is up, line protocol is up Internet address is 2.2.2.2/24 Multicast routing: enabled Multicast switching: fast Multicast packets in/out: 0/0 Multicast TTL threshold: 0 Multicast Tagswitching: disabled c3750x#sh ip traff IP statistics: Rcvd: 42044197 total, 2284946 local destination 0 format errors, 1722248 checksum errors, 0 bad hop count 427 unknown protocol, 38037022 not a gateway 0 security failures, 0 bad options, 3109719 with options Opts: 0 end, 0 nop, 0 basic security, 0 loose source route 0 timestamp, 0 extended security, 0 record route 0 stream ID, 0 strict source route, 3109719 alert, 0 cipso, 0 ump 0 other Frags: 0 reassembled, 0 timeouts, 0 couldn't reassemble 0 fragmented, 0 couldn't fragment Bcast: 1973326 received, 2 sent Mcast: 280568 received, 2457 sent Sent: 33636 generated, 0 forwarded Drop: 14 encapsulation failed, 0 unresolved, 0 no adjacency 0 no route, 0 unicast RPF, 0 forced drop 0 options denied, 0 source IP address zero ICMP statistics: Rcvd: 0 format errors, 0 checksum errors, 0 redirects, 5 unreachable 23 echo, 0 echo reply, 0 mask requests, 0 mask replies, 0 quench 0 parameter, 0 timestamp, 0 info request, 0 other 0 irdp solicitations, 0 irdp advertisements Sent: 0 redirects, 4 unreachable, 5 echo, 23 echo reply 0 mask requests, 0 mask replies, 0 quench, 0 timestamp 0 info reply, 0 time exceeded, 0 parameter problem 0 irdp solicitations, 0 irdp advertisements TCP statistics: Rcvd: 31017 total, 0 checksum errors, 0 no port Sent: 31136 total EIGRP-IPv4 statistics: Rcvd: 0 total Sent: 0 total PIMv2 statistics: Sent/Received Total: 0/0, 0 checksum errors, 0 format errors Registers: 0/0 (0 non-rp, 0 non-sm-group), Register Stops: 0/0, Hellos: 0/0 Join/Prunes: 0/0, Asserts: 0/0, grafts: 0/0 Bootstraps: 0/0, Candidate_RP_Advertisements: 0/0 Queue drops: 0 State-Refresh: 0/0 IGMP statistics: Sent/Received Total: 2457/280568, Format errors: 0/0, Checksum errors: 0/0 Host Queries: 2457/0, Host Reports: 0/268009, Host Leaves: 0/6556 DVMRP: 0/0, PIM: 0/0 Queue drops: 0 UDP statistics: Rcvd: 1972906 total, 0 checksum errors, 1705762 no port Sent: 17 total, 0 forwarded broadcasts OSPF statistics: Last clearing of OSPF traffic counters never Rcvd: 0 total, 0 checksum errors 0 hello, 0 database desc, 0 link state req 0 link state updates, 0 link state acks Sent: 0 total 0 hello, 0 database desc, 0 link state req 0 link state updates, 0 link state acks ARP statistics: Rcvd: 10337749 requests, 671 replies, 0 reverse, 0 other Sent: 85 requests, 478 replies (0 proxy), 0 reverse Drop due to input queue full: 0 CheckSumm Error и Alert постоянно растут, почему тоже не знаю. Приму любую помощь в понимании происходящего и в понимании того как этим потоком управлять. Заранее благодарен.
