Ano ja som ho mal v zivej prevadzk na PIM-SM spolu s SSM a zaroutovany aj cely internet a zapnute BGP4 v ipv4 aj ipv6.
Myslim ze neni absolutne ziadny problem si s alternetivom dohodnut mescanu testovacku...a skusit a sam uvidis. |

Od nasadenia dvoch dcn3950 mam neskutocne problemy s iptv. Obe switche posielaju igmp query zo source ip 0.0.0.0 a obraz seka, akebo sa zastavy kym neprepnem kanal.
Skusal som uz vypnut igmp querier ale bud som to vypinal zle alebo nepomohlo
no ip igmp snooping vlan 1 l2-general-qurier
Problemom je samozrejme aj to, ze nemam vytvorenu vlanu pre multicasty, ale ajtak, taketo problemy som pred nasadenim dcn switchov nemal...
Neviete mi poradit ako by som to vedel vyriesit? |

| obavam sa ze jedine riesenie je vymenit svice ... ja som s nimi prisiel o 2 roky zivota a velmi dolezitu poziciu na trhu s iptv, a uz mi to nestoji za to ich znova testovat |

A ja ich veselo nasadzujem miesto edgecore 3528m afunguju excelentne....
Otazka znie preco?
Klavesnica vs stolicka?
Yeager este pripomeniem ze vsetko jazdis vo vlan 1 teda switche vkonfe by default. |

| moja rec, tiez nemame s edgecore ziadne problemy. a zaroven konstatujem, ze ak su switche v default, teda ze vo vlane 1 je manazment aj data aj multicast, tak by som sa problemom vobec necudoval... na takychto metro sietach multicast patri do osobitnej vlany a manazment urcite tiez |

jasne ze hej len v vylepsenej podobe bez nutnych sprstosti ako konfigurovat mvr zaznamy...kratka ukazka
ip igmp snooping
ip igmp snooping vlan 90
vlan 90
name MCASTY
multicast-vlan
multicast-vlan association 295
toto tu znaci ze vlana 90 je multicastova a ze je povolene dorucit mcasty do vlany 295 ked klient poziada.Takze ked STB nasupes do vlany 295 nebude v nej nijaka prevadzka , predpoklada sa iba DHCP server pre STB.
Samozrejme mozes si tam dat viacero zaznamov len pre konkretne porty dalsie vlany atd.
Je pritom na rozdiel od edgecore ci port je alebo nie v hybrid mode (inak MVR nepojde alebo mu bude jebat)
Kludne vsetky porty od userov daj ako access a multicast pojde tam kde mu to dovolis. |

a preco vlastne MVR ? ak to budem cislovat tak ako ty, tak u nas vlan90 je iba v ciscu a medzi ciscami na backbone, a vlan295 je v ciscu aj edgecoroch. DHCP tam robi cisco a aj routing multicastu medzi vlan90 a vlan295 robi cisco. edgecore sa stara iba o to ze na ktorych oprtoch je vlan295 zapnuta a aby nad nou robil IGMP. |

| No lebo v prvom rade som ho nechcel mylit este viac, ani u nas neni vlan 90 zdroj mcastov ale uplne ina vlana. do 90 ky hu dostavame sprostym routingom pim-sm, ale to nebrani mat samotne stb este dalsej vlane. preco mvr/multicast vlan? no preto ze je to celkom efektivny sposob ako dorucit mcast userom priamo iba na jeho acces porte s kompcom moznosti ako co preco kolko moze a nemoze pozerat. nastavit urcity profil, obmedzenia bez toho abysom mal na porte milion roznych acces listov, querier ochran a podobnych veci. ono rozhodit mcastove routovanie neni zas az taky problem ked je klient chuj/zakerak. treba si kuknut mvr co secko sa da s nim zriesit by default a je to... |
