ahojte, mam problem s routovanim multicastu cez mikrotiky
Sender -- (subnet I) --> Router A -- (subnet II) --> Router B -- (subnet III) --> Receiver
Sender:
linux streamer getstream pusta stream na UDP 224.0.1.20:1234
ip 10.0.2.2/24
route -n
Destination Gateway Genmask Flags Metric Ref Use Iface
224.0.1.20 10.0.2.1 255.255.255.255 UGH 0 0 0 eth0
10.0.1.0 10.0.2.1 255.255.255.0 UG 0 0 0 eth0
10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
#####configuration script for router A
###
/ip address
add address=10.0.2.1/24 interface=ether1
add address=10.0.0.2/24 interface=ether2
/ip route
ip route add dst-address=10.0.1.0/24 gateway=10.0.0.1
/routing pim interface
add
/routing pim rp
add address=10.0.0.2
#####configuration script for router B
###
/ip address
add address=10.0.1.1/24 interface=ether1
add address=10.0.0.1/24 interface=ether2
/ip route
ip route add dst-address=10.0.2.0/24 gateway=10.0.0.2
/routing pim interface
add interface=ether1
add interface=ether2
/routing pim rp
add address=10.0.0.2
na strane klienta je linux s vlc, a neprehrava udp 224.0.1.20:1234... ked pustim stream cez unicast tak bezproblemov slape, takze routovacie pravidla aj ipcku su istotne OK... bol by niekto taky mily a poradil mi kde mam hladat chybu a od coho sa mam odpichnut? dakujem |

tcpdump je tvoj kamarát
Forcni mu IGMPv2, lebo defaultne asi posiela IGMPv3. Robí sa to takto
Code: › echo 2 > /proc/sys/net/ipv4/conf/eth0/force_igmp_version
Prípadne si vypni rp_filter |
