Приветствую, господа)

 

Имеем Juniper, который получает несколько каналов по msdp+pim от источника.

Имеем cisco, у которой есть линк c juniper'ом.

 

Задача отдать IPTV с juniper на cisco и с cisco абонам.

Делаю так:

Juniper:

interfaces {
   xe-0/0/0 {
       unit 1950 {
           description IPTV_DOWNLINK;
           vlan-id 1950;
           family inet {
               address 172.16.24.125/30;
           }
       }
   }
   lo0 {
       unit 0 {
           family inet {
               address 127.0.0.1/32;
               address 10.1.1.1/24;
           }
       }
   }
}
routing-options {
   multicast {
       ssm-groups 239.32.4.0/24;
       asm-override-ssm;
       forwarding-cache {
           timeout 60;
       }
   }
}
protocols {
   igmp {
       interface xe-0/0/0.1950 {
           version 2;
       }
       interface ae0.1132 {
           version 2;
       }
   }
   msdp {
       peer xxx.zzz.195.190 {
           local-address xxx.zzz.195.189;
       }
   }
   pim {
       rp {
           local {
               address 10.1.1.1;
               priority 5;
               hold-time 200;
               group-ranges {
                   239.32.4.0/24;
               }
               override;
           }
       }
       interface fxp0.0 {
           disable;
       }
       interface xe-0/0/0.1950 {
           mode sparse;
           version 2;
       }
       interface ae0.1132 {
           mode sparse;
           version 2;
       }
       interface lo0.0 {
           mode sparse;
           version 2;
       }
   }
}

 

Cisco:

ip multicast-routing 
ip multicast multipath
ip pim rp-address 10.1.1.1 IPTVDS override
!
interface Vlan1950
ip address 172.16.24.126 255.255.255.252
ip pim sparse-mode
end
!
interface Vlan10
ip address 10.20.30.1 255.255.255.0
ip pim sparse-mode
end
#show ip access-lists IPTVDS            
Standard IP access list IPTVDS
   10 permit 239.32.4.0, wildcard bits 0.0.0.255 (3627 matches)

 

Проблема собственно в чем. У абонента включенного в 10ый влан IPTV работает 10 минут, потом 10 минут не работает. Не могу понять в чем проблема. Подскажите куда рыть.

Свитч не при чем. Есть другой поток который приходит на циску по pim. И у абонента другой поток работает.

Да и напрямую с циски ситуация аналогичная, то есть, то нет. Причем настройки ни на циске ни на джуне не меняются.

Когда есть поток на циске видим следующее:

#show ip mroute 239.32.4.3
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
      L - Local, P - Pruned, R - RP-bit set, F - Register flag,

      U - URD, I - Received Source Specific Host Report,

      Y - Joined MDT-data group, y - Sending to MDT-data group
      V - RD & Vector, v - Vector

 Incoming interface: Null0, RPF nbr 0.0.0.0, Mroute
 Outgoing interface list:
   Vlan10, Forward/Sparse, 00:02:26/00:02:30

 

И когда потока нет:

#show ip mroute 239.32.4.3
IP Multicast Routing Table
Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected,
      L - Local, P - Pruned, R - RP-bit set, F - Register flag,

      X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement,
      U - URD, I - Received Source Specific Host Report,
      Z - Multicast Tunnel, z - MDT-data group sender,
      Y - Joined MDT-data group, y - Sending to MDT-data group

 Outgoing interface list:
   Vlan10, Forward/Sparse, 00:40:04/00:02:22, H

 

И еще. Когда есть поток, то на джунипере нагрузка цпу поднимается примерно на 10-15%

Так. Есть новые подробности.

Прокинул просто влан с джунипера к абоненту и отдал мультик просто про igmp. Ситуация аналогичная. Поток то есть, то его нет. Циска тут уже не при чем. Это либо поставщик, либо какие-то настройки на джуне.

Осталось понять только какие и почему растет нагрузке на цпу на 15-20%, когда появляется поток.

Юнипер знает маршруты до источников мультикаста? Загрузка может из-за этого быть. Аналог ip mroute в циске.

Однако, когда я мониторю, то поднятие нагрузки на цпу не совпадает с этими сообщениями.

Сменили vlan и интерфейсную пару - все заработало.

 

Теперь есть еще вопрос.

Есть еще один поток, который я получаю по mbgp+msdp. Подскажите как мне его принять и раздать дальше по pim'у? )
